71952 ACDGA/P4AL 360 mm 260 mm 46 mm Frequently Asked Questions about 71952 ACDGA/P4AL Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies 71952 ACDGA/P4AL with a precision bore diameter (d) of 260 mm, an outside diameter (D) of 360 mm, and a nominal ring width (B) of 46 mm. This configuration yields an effective cross-sectional wall thickness of 50.0 mm and an envelope ratio (D/d) of 1.38, delivering compact rigidity for OEM machinery housings.
To safeguard CHG Bearing 71952 ACDGA/P4AL against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (260 mm x 360 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
The Open Type engineered for 71952 ACDGA/P4AL by CHG Bearing utilizes precision non-contact metal shields or reinforced NBR/FKM contact lip seals. This barrier prevents particulate ingress, washdown fluids, and abrasive dust from reaching the raceways while eliminating grease leakage under centrifugal forces.
Standard batches of CHG Bearing 71952 ACDGA/P4AL conform strictly to ISO Class Normal (ABEC-1). For high-precision machine tool spindles, gearboxes, or robotics requiring tighter runouts, CHG Bearing can provide custom batches graded to ISO Class 6 (P6/ABEC-3) or ISO Class 5 (P5/ABEC-5) with 100% micrometer verification.
