Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies HKG045CP4 with a precision bore diameter (d) of 114.3 mm, an outside diameter (D) of 165.1 mm, and a nominal ring width (B) of 25.4 mm. This configuration yields an effective cross-sectional wall thickness of 25.4 mm and an envelope ratio (D/d) of 1.44, delivering compact rigidity for OEM machinery housings.
Sourcing HKG045CP4 directly from CHG Bearing eliminates intermediate brokerage markups while granting you factory-direct engineering backup, rigorous ISO-certified quality assurance, competitive volume wholesale pricing, and dependable supply chain stability for Thin Section Deep Groove Ball Bearings.
Standard batches of CHG Bearing HKG045CP4 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.
The CHG Bearing HKG045CP4 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.
