608 8*22*7mm Deep Groove Ball Bearing 608-2RS Black Rubber Sealed Bearings Fit for Skateboard 3D Printer Wheel Roller Skates

608 8*22*7mm Deep Groove Ball Bearing 608-2RS Black Rubber Sealed Bearings Fit for Skateboard 3D Printer Wheel Roller Skates

Product description
This 608-2RS miniature ball bearing is made of chrome steel and has rubber seals. It has an 8 mm inside diameter, a 22 mm outside diameter, and a 7 mm depth. The bearing has deep groove geometry for supporting both radial and axial loads and high speeds. The races are made of chrome steel for durability and resistance to deformity under heavy loads. Rubber seals on both sides of the bearing help retain lubricant and exclude contaminants. The static load rating is 141 kgf and the dynamic load rating is 336 kgf. The maximum speed with oil lubrication is 40,000 revolutions per minute (rpm). This deep groove ball bearing is used in applications such as skateboards and rollerblades, among others.

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.
