Frequently Asked Questions about 71813 ACDGA/HCP4 Super-precision Angular Contact Ball Bearings

Find key technical answers regarding dimensions, specifications, and replacement options for this model.

To safeguard CHG Bearing 71813 ACDGA/HCP4 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (65 mm x 85 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
As standard production, CHG Bearing subjects 71813 ACDGA/HCP4 to precision bainite or martensite quenching, offering dimensional stability up to 120°C (248°F). For high-heat processing equipment, CHG Bearing also supplies custom S0 (150°C), S1 (200°C), or S2 (250°C) stabilization heat treatments upon request to prevent residual austenite transformation.
Each 71813 ACDGA/HCP4 produced in CHG Bearing manufacturing facilities features accurately profiled corner chamfers complying with DIN 5412 / ISO standard corner radii. When designing mating shafts and housing shoulders, machining an undercut or fillet radius strictly within the inner ring clearance limit (65 mm bore side) ensures perfect planar contact without edge binding.
Absolutely.
