S71916 ACEGA/P4A 110 mm 80 mm 16 mm Frequently Asked Questions about S71916 ACEGA/P4A Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The CHG Bearing S71916 ACEGA/P4A 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.
To safeguard CHG Bearing S71916 ACEGA/P4A against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (80 mm x 110 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Absolutely. The CHG Bearing S71916 ACEGA/P4A Super-precision Angular Contact Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF S71916 ACEGA/P4A, FAG S71916 ACEGA/P4A, NSK S71916 ACEGA/P4A.
