HKD045CP0 139.7 mm 114.3 mm 12.7 mm Frequently Asked Questions about HKD045CP0 Thin Section Deep Groove Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
When fitting HKD045CP0 over a 114.3 mm shaft, CHG Bearing strictly recommends uniform induction heating (controlled between 90°C and 110°C) or precision hydraulic press sleeves. Under no circumstances should direct impact blows be struck against the rings or cage, as shock loads cause brinelling indents and premature spalling.
Standard batches of CHG Bearing HKD045CP0 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.
Built for demanding industrial environments, the HKD045CP0 Thin Section Deep Groove Ball Bearings by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
To safeguard CHG Bearing HKD045CP0 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (114.3 mm x 139.7 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
