Model Number: XYB-15.875-19.05-22.225-25.4 Brand Name: XYB or OEM Key Specifications/Special Features: More than 20 years manufacturing experience serve you better productions and services.Not only can a professional steel ball manufacturer be chosen.The working flow of steel balls:Heading: In the first step, heading machines cut wire into short lengths and form it into sphericalshapesbetween dies.
Deflashing:
The flash line, a ridge left by the forming dies, is removed as balls roll between heavy,castiron plates.
Soft Grinding:
Similar todeflashing, except that a grinding stone is used to improve precision.
Heat-treating:
Carbon steel balls are next carburized and hardened. Heat treatment impartsthe desiredhardness and case depth.
Descaling:
This step removes the residues and by-products from the heat-treating process.
Hard Grinding:
Slow, meticulous grinding assures proper sizing andsphericity, withtolerances as close as ±.0001".
Lapping:
Several proprietary lapping processes can bring balls to the requirementsof ISO 3290 Grade10 - 48.
Finishing:
Proprietary chemical and mechanical processes give the balls their finalmicro-smoothedfinish, for increased wear resistance and product longevity.


Applications:

Precision bearings, automotive components (brakes, steering, line shaft), bicycle, agitators, appliances, sliders, quick couplings, machine tool, lock mechanisms, conveyor belts, skates, pens, pumps, castors, measurement instruments, valves
