Sackorange 608 ZZ Skateboard Bearings, Double Shielded,8x22x7 Miniature Ball Bearings Pack of 20)

 Ean: 0730060656304   |    PartNumber: CS-sack-038   |   Asin: B07216D1SZ

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. These bearings come in a pack of 20.
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.

Package included:20 x 608zz

Features

  • Single-row bearing for supporting radial loads
  • Shields on both sides of the bearing to keep lubricant in and contaminants out
  • Carbon steel for durability and resistance to deformity under heavy loads
  • 34,000 rpm limit with grease lubrication
  • Dimensions suitable for use in such applications as skateboards, inline skates, and scooters
