HM237545/HM237510D 288.925 mm 177.8 mm 142.875 mm Frequently Asked Questions about HM237545/HM237510D Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
As standard production, CHG Bearing subjects HM237545/HM237510D to precision bainite or martensite quenching, offering dimensional stability up to 120°C (248°F). For high-heat processing equipment, CHG Bearing also supplies custom S0 (150°C), S1 (200°C), or S2 (250°C) stabilization heat treatments upon request to prevent residual austenite transformation.
Every production batch of CHG Bearing HM237545/HM237510D Double Row Tapered Roller Bearings comes with complete traceability. Upon shipment, CHG Bearing can provide EN 10204 3.1 Material Test Reports (MTR), Certificates of Conformity (CoC), spectral chemical composition analysis, and dimensional inspection sheets.
Model HM237545/HM237510D is manufactured by CHG Bearing in standard Normal clearance (CN) for ambient temperature transmission, and C3 or C4 clearance for heavy duty applications. C3 clearance compensates for radial shrinkage caused by tight shaft press-fits (bore 177.8 mm) and steep thermal gradients between inner and outer rings.
To safeguard CHG Bearing HM237545/HM237510D against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (177.8 mm x 288.925 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
