S71915 CD/P4ADT 105 mm 75 mm 32 mm Frequently Asked Questions about S71915 CD/P4ADT Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The CHG Bearing S71915 CD/P4ADT is rated for limiting speeds up to standard rated RPM under forced oil-mist or circulating oil lubrication regimes. When lubricated with factory-filled synthetic high-speed grease, safe continuous velocity is maintained at approximately 75% to 85% of the maximum nominal limit, preventing thermal runaway.
As standard production, CHG Bearing subjects S71915 CD/P4ADT 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.
Model S71915 CD/P4ADT is manufactured by CHG Bearing in standard Normal clearance (CN) for ambient temperature transmission, and C3 or C4 clearance for heavy duty applications. C3 clearance compensates for radial shrinkage caused by tight shaft press-fits (bore 75 mm) and steep thermal gradients between inner and outer rings.
To safeguard CHG Bearing S71915 CD/P4ADT against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (75 mm x 105 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
