Pack of 100 Skateboard/Inline Skate Bearing Nylon Cage Sealed Ball Bearings VXB Brand with Green Rubber Seals

This 608-2RS ball bearing is made of chrome steel and is double sealed. It has an 8 mm inside diameter, a 22 mm outside diameter, and a 7 mm depth. This single-row ball bearing has deep groove geometry for applications that require high speeds and support both radial and axial loads. This bearing is made of chrome steel for durability and resistance to deformity under heavy loads. It has Normal radial internal clearance for applications that do not involve thermal expansion or atypical precision. This ball bearing conforms to ABEC 1 precision standard for performance within a narrow range of variation. Rubber seals on both sides of the bearing keep the lubricant in and contaminants out. A nylon cage spaces the balls for even load distribution and prevents contact to reduce friction, vibration, and noise. This deep groove ball bearing is suitable for use in applications such as inline skates and skateboards.

Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. All rolling bearings are open, shielded, or sealed. Sealed bearings are lubricated with oil or grease in the bearing factory, while open and shielded bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use. The shield protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.
