Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To safeguard CHG Bearing 618/500P4 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (500 mm x 620 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Standard batches of CHG Bearing 618/500P4 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies 618/500P4 with a precision bore diameter (d) of 500 mm, an outside diameter (D) of 620 mm, and a nominal ring width (B) of 56 mm. This configuration yields an effective cross-sectional wall thickness of 60.0 mm and an envelope ratio (D/d) of 1.24, delivering compact rigidity for OEM machinery housings.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for 618/500P4. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
