Uxcell Precision Balls 33mm Solid Chrome Steel G25 for Ball Bearing Wheel

Descriptions:1.These high precision ball bearings are hot forged from bar stock. Great for applications where there will be extreme rotation.2.Modern furnaces with precisely controlled atmospheres and temperatures are used for heat treating to assure uniform hardness and proper microstructure for each steel ball.3.Ball hardness is controlled within the 60-63 HRC range as measured on parallel flat surfaces. The steel balls come lightly lubricated to keep their perfect polish.4.Bearing balls are used for semi-precision bearings, casters, locks, and drawer slides.5.Other applications for steel bearing balls include bicycles, casters, drawer slides, door locks.Specifications:Precision Grade: G25Hardness(HRC): 60-63Material: High Carbon Chromium Bearing Steel (GCr15)Package Contents:1 x Bearing Ball
