YBGCr15 Chrome Steel Balls For Ball Transfer Units 5.5562MM 12MM 22.22MM

Characteristics

Low alloy hardened chromium steel balls, they show excellent hardness, wear resistance,

very good surface finishing and dimensional stability.

Applications

Precision bearings, automotive components (brakes, steering, line shaft), ball transfer units,

linear ball bearings, bike and motor-bike components, appliances, quick couplings,

machine tool, lock mechanisms, conveyor belts, skates, ball pens, pumps, castors,

measurement instruments, valves, recirculating balls.

Utilized in browning, polishing and milling machineries.
