1. 500 Piece Assorted Loose Bicycle Bearing Balls 1/8", 5/32", 3/16" 7/32" & 1/4"
Feature
Each size is individually packaged and labeled (see photos)Precision grade G25 balls
100 balls each of the following sizes: 1/8", 5/32", 3/16" 7/32" & 1/4"
AISI 52100 chromium steel
Description
The finest quality chrome steel produced in accordance with the highest industry standards. These high precision G25 ball bearings are hot forged from bar stock. Modern furnaces with precisely controlled atmospheres and temperatures are used for heat treating to assure uniform hardness and proper microstructure for each stainless steel ball. Throughout the manufacturing process, statistical process control assures tolerance accuracy, fine surface finish and consistent high quality. Chrome steel balls offer the precise geometry and fine surface finish that makes them especially useful for bicycles, casters, drawer slides, door locks and many other applications.2.

Feature
Single-row bearing for supporting radial loadsShields 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
Description
This 608ZZ bearing is a double shielded miniature ball bearing measuring 8x22x7. This single-row bearing is built to support radial loads and has a revolutions per minute (RPM) limit of 34,000 with greased lubrication. It is made from carbon steel for durability and resistance to deformity under heavy loads. This bearing is shielded on both sides to keep lubricant in and contaminants out. The 608ZZ bearing is suitable for use in such applications as skateboards, inline skates, and scooters and comes in a pack of eight.
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.
