General vs Type-X
These 2 types of bearings feature different radial play (distance between the balls and the inner raceways) and lubrication. A zero slop ball bearing might not be the type you need for your r/c vehicle.
General ball bearings are good for all purposes with low maintenance. This is the type of bearings you want to use in your backyard bashers. They work extremely well with high precision parts such as aluminum uprights, 2nd speed spur gear.
Type-X ball bearings are specially made for your racing machines with dedicated radial play and lubrication. They are very low friction and can withstand unprecision found in composite/plastic parts. Some of them are light oiled and require frequent maintenance.
Shield Types
Metal shields work well on clean surfaces and within sealed gearboxes such as electric touring car. They are zero friction but require high maintenance.
Rubber shields are ideal for dirt & endurance. They seal better but not in full contact with the inner ring. A smaller gap keeps lubrication within while keeps dirt away. They are easy to take off for maintenance.
Open type ball bearings are usually forced to be manufactured this way because of thickness of the bearing itself. It can only be used within sealed gearboxes.
Engine Ball Bearings
Custom made for r/c engines with dedicated tolerance, radial play and parts. They are made to be used under high temperature.
Thrust Ball Bearings
Specially made for differentials and push type clutches. Size of balls, number of balls and pressure plates are different from those you can get in bearing stores.
Ceramic Balls
Made of solid silicone nitride (Si3N4), not coated nor anodized, grade 5. They are very lightweight and much much harder than any know steel. Low friction and long lasting. These are also the type of balls used in our ceramic hybrid ball bearings.
What does ABEC Mean?
The ABEC scale is a system used throughout the manufacturing industry for rating the manufacturing tolerances of precision bearings, developed by the Annular Bearing Engineering Committee (ABEC) of the American Bearing Manufacturers Association (ABMA). Bearings are rated using an odd number between 1 and 9. The higher the number, the greater the manufactured precision of the bearing. Bearings manufactured within tighter tolerance ranges provide greater accuracy of shaft rotation and contribute to higher speed capability. However, the ABEC rating does not specify many other critical factors, such as smoothness of the rolling contact surfaces, ball precision, and material quality.
There are no required materials to meet the ABEC specifications required to be rated on the scale, but the bearings must be made to a certain accuracy and precision. Bearings not conforming to at least ABEC 1 are not precision bearings. ABEC and ISO precision gradings are used for bearings throughout the industry.
The scale is designed to allow a user to make an informed decision about the type of bearing they are purchasing. High rated bearings are intended for precision applications like aircraft instruments or surgical equipment. Lower grades are intended for the vast majority of applications such as vehicles, mechanical hobbies, skates, fishing reels and industrial machinery. High ABEC rated bearings allow optimal performance of critical applications requiring very high RPM and smooth operation. High ABEC rated bearings do not make equipment go faster however they allow high precision equipment to operate at their optimum speed and efficiency.
What is Ceramic Hybrid?
Ceramic "Hybrid" Ball Bearings mean the rolling elements, or balls, are ceramic, but the inner and outer rings are still conventional steels. Basicly it means regular ball bearings with silicone nitride, (Si3N4) ceramic balls. Ceramic ball bearings combine the advantages of super smooth, lightweight and durability. Ceramic balls are much more lightweight than conventional balls, dramatically results in reduced centrifugal force on the ball bearing rings, and their superior thermal properties prevent damaging heat buildup at the interface between the balls and the bearings races. Ceramic balls also offer superior resistance to deformation under load keeping them rolling smoothly.
