Specification AgeRangeDescription : Adult BatteriesRequired : 1 Brand : Onwon BulletPoint1 : Carbon steel for durability and resistance to deformity under heavy loads. Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. BulletPoint10 : 90-Day satifaction guarnetee BulletPoint2 : Shields on both sides of the bearing for protection from dirt, rocks, dust, to lengthen the life of the bearing and maintain precision BulletPoint3 : Max rpm 34000 with grease. Pre-lubricated with grease, less friction, requires minimal maintenance BulletPoint4 : High precision high speed bearings used with Skateboards, Longboards, Inline Skates, Rollerblades, Electric Skateboards, and many other rolling applications BulletPoint5 : PRODUCT WARRANTY: If you receive defective Bearings or missing Bearing set, please CONTACT US for free replacement.

This 608ZZ shielded 8x22x7 miniature ball bearing is a single-row bearing for supporting radial loads. The bearing is made of carbon steel for durability and resistance to deformity under heavy loads, and is shielded to keep lubricant in and contaminants out.
it has a revolutions per minute (RPM) limit of 34,000 with grease lubrication. The dimensions of this bearing make it suitable for use in skateboards, inline skates, and scooters, 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.
