Roller Bearings Provide Many Benefits Over Ball Bearings

hybrid ceramic bearing



Consumers are Finding their Bearings at VXB Ball Bearings

Choosing from all of the different types of bearings that are available, it is hard to figure out which kind is actually the best when designing any type of machinery.  Some people like the roller bearings better, but others like the ball bearings better for their projects.

The roller bearings may be able to provide some benefits over the ball bearings when they are using them in industrial uses.  This is because a roller bearing does not create as much friction.  With the reduced friction, it could give the company a big savings on their electricity bill.

These will also reduce the fire hazard, do not require lubrication and are overall cleaner to use that other types.  VXB Ball Bearings has many different opportunities for different kinds of bearings, including the roller bearings.  They have a lot of sizes also. 

The company spokesman added, “We know how hard it can be to find the right size of bearing in the style that is necessary.  We have many different options for all of our customers.  Roller bearings, ball bearings and more can be found with a click of the mouse.”

Every piece of machinery uses a different type of motor and will do something different.  This means that it has to be able to hold up when it is being worked at its hardest.  Not all machines are going to be ran at their full capacity, but if someone wants to do this, they need to know that it is possible.
The faster that it runs, the harder it will be on many of the machines though.  These are something that is going to be very important for industries.  They may increase the speeds and make sure that they have the parts on hand in case something happens.

VXB Ball Bearings will not limit the number of bearings that can be purchased at one time.  This is something that machines need and every company has a different number of machines.  They feel that there is no reason why they cannot be prepared if something breaks either.

Roller bearings can hold up to a lot of situations though.  They are also easily replaced when they need to be replaced.  The sizes and styles are going to be determining the cost and what they are going to get used for.  There are many possibilities in the industrial world when people are using bearings.

About Us:  Getting the right kind and size of bearings is not always an easy task.  When something breaks, it cannot be started back up if the bearings gave out.  This is a very important part of the operation in many industries and for personal equipment.  VXB Ball Bearings has millions of different kinds and sizes of bearings to choose from.  Their customers can order directly through their website 24 hours a day, seven days per week.  They ship all over the world to many customers.  They carry bearings from only the top quality brands.  Check out their huge selection of bearings at http://www.vxb.com.

The FIRST Robotics


vxb.com is a Proud Sponor

The FIRST Robotics Competition is an international high school robotics competition organized by FIRST (For Inspiration and Recognition of Science and Technology). Each year, teams of high school students compete to build robots weighing up to 120 pounds (not including battery and bumpers) that can complete a game that changes yearly. While teams are given a standard set of parts, they are also allowed a budget and encouraged to buy or make specialized parts as long as they conform to FIRST safety rules. Game details are given at the beginning of January and the teams are allowed six weeks to construct a competitive robot, that can operate autonomously as well as when guided by wireless controls, to accomplish the game's tasks.

          Every year, a different game is played. However, many of the game rules have not changed. Teams are randomly assigned in groups of 3 people, which are paired into qualification matches, where they earn 'qualifying points', the calculation of which changes each year. The game changes every year, but for the most part, they involve some autonomous (computer controlled) robot operation for 10–15 seconds at the beginning of a match, followed by a much longer period (usually 2 minutes) of remote control. The FIRST Robotics Competition involves teams of mentors (corporate employees, teachers, or college students) and high school students who collaborate to design and build the robot. The game is designed by FIRST and changes from year to year. This game is announced at a nationally simulcast kickoff event in January. VXB.com is a proud sponsor of a team in the First Robotics Competition. We encourage the participants as they may be responsible for some significant technological advances in years to come.

Linear Shafts vs Axles

By  http://www.vxb.com/


What is the difference between a linear motion shaft and a pin shaft? The answer is: The Tolerance. 

            A linear motion rail is designed to have linear bearings move across the shaft. These rails are usually designed with a tolerance of -15 to -20 microns; enough undersized to accommodate the tolerance of the bearing and allowing it to glide smoothly up and down the shaft. Examples of these shafts are 3D printer machines, manufacturing plant machines, molding machines, etc.

            A pin/axle shaft has a tolerance of +10 to +20 microns. A bearing would need to get press fit onto this shaft to fit snug. You can find these sorts of shafts/pins in pretty much most common applications such as roller skates, skateboards, ceiling fans, fans, etc.

Shaft is desired to transfer the motion (rotary), from one member to another, where as the axle is used to support the bearing in rotary motion.  For example, if you were to use a linear shaft as an axle, you would find that the bearing would fit loosely around the shaft. The bearing therefore it would be unstable and may cause problems in the application. On the other hand, if an axle shaft were to be used as a linear shaft, you will find that the linear bearings would not glide up and down. The bearings would get stuck. We often get calls from customers with this problem. It is important to distinguish what type of shaft you need according to your application. For any questions, call us, we are happy to help.

Ball Bearings Heat and Clearance


Ball and Roller bearings unmounted have internal clearance. This clearance is an actual air gap. As bearings are mounted and pressed onto shafts some of the air gap is removed. As bearings operate the shaft is normally hotter than the housing causing a thermal unbalance which results in more clearance removal.
 
There are 3 key points to consider when purchasing a bearing:
 
1. Clearance of the bearing- When heat is involved, the tolerance of the bearing will determine the amount of space the bearing has to expand. You will typically find bearings with C0 clearance. The next larger clearance is a C3, C4, and then C5. Each clearance allows a certain amount of space between the ball bearing and outer race.
 
2. The material of the bearing: Under too much heat, chrome steel and stainless steel will rust. This limits the amount of heat the metal can take. Your standard chrome steel can handle up to 250ºF. If a bearing exceeds the heat temperature rating, it will fail. Stainless steel can handle more heat. The metal in high temperature bearings is heat treated to be able to withstand higher temperatures.
 
3. Cage: You will notice that all of the high temperature bearings have no cage (full compliment). This is due to the fact that the bearings expand under heat. If a bearing is encased in a cage, once heated, the bearing will break the cage causing the bearing to fail.

The Needle Roller Bearings Different Types

http://www.vxb.com/page/bearings/CTGY/NEEDEL_ROLLER

Machined type: The machined type of needle roller bearing can carry the most weight out of the 3 types. This bearing is manufactured from a
Machined Type Needle Roller Bearings are bearings with a low sectional height and large load ratings. The outer ring has high rigidity and can easily be used even for light alloy housings. These bearings are available in metric series and inch series, both of which have the caged type and the full complement type. It is possible to select a suitable bearing for use under various conditions such as heavy loads and high-speed or low-speed rotations. In addition, there are bearings with and without an inner ring. As the type without inner ring uses a shaft as the raceway surface, a compact design is possible

Drawn type: Drawn cup roller clutches are designed to transmit torque between the shaft and housing in one direction and allow free overrun in the opposite direction. These designs utilize the same small radial section as drawn cup needle roller bearings. The units are compact, lightweight and operate directly on a hardened shaft. These bearings are manufactured from pressed steel molds.  Proper mounting is easily accomplished with a simple press fit in the housing. Clutches and clutch and bearing assemblies are offered both in inch and metric nominal series. The Metric sizes for these bearings start with “HK” and the inch series starts with “SC” on our website.

Cage roller: The caged roller bearings are great for low profile designs in applications. This design is basic and takes up less space than a machined roller bearing. Needle roller and cage assemblies are ready-to-mount, self-contained bearing components. They are an excellent choice for applications that require a very rigid bearing arrangement as well as a high load carrying capacity. If the shaft and housing bore can serve as raceways, needle roller and cage assemblies require minimal radial space. The part number for this bearing starts with a K on our website.

Most Frequent Causes of Bearing Failures


Most Frequent Causes of Bearing Failures
 
Did this bearing really fail again!? Here are a few reasons for bearing failure to consider when experiencing difficulty with your bearing:
1.     Inadequate Lubrication: 54% of bearing failures are due to the lack or excess of lubrication in the bearing. The bearing should have 20% to 30% lubrication.
2.     Improper Sealing: If you bearing is susceptible to contaminants, make sure it is sealed to protect it.
3.     Overload or Excessive Speed
4.     Damage from surrounding parts
5.     Improper mounting or mishandling
6.     Manufacturing defects.

Rusting and corrosion is oxidation of the steel


Rusting and corrosion is oxidation of the steel. by www.vxb.com This can cause pits on the surface of the rings and rolling elements causing the bearing to cease. What causes corrosion? Well, there are a few causes of corrosion: Ingress of water, condensation of moisture in the air, poor packaging/storage conditions, and handling the bearing with bare hands. To prevent rusting one must ensure proper storage and proper sealing mechanism. These measures will prevent corrosion during long periods of mom-operation.

Would you like a cone or cup?


Would you like a cone or cup? This bearing comes with both! This single-row tapered roller bearings has the capacity to carry radial and axial load in one direction simultaneously (cone + cup). The sliding motion between the inner ring and flange and the roller end is the primary heat generation source. They have optimized the design of this critical area to reduce heat build up. The featured 30219 bearing is a metric standard taper bearings and measures 95mm x 170mm x 34.5mm and is made of chrome steel. http://www.vxb.com/page/bearings/PROD/Kit7101
