DHK07.0143P5 488.95 mm 355.6 mm 317.5 mm Frequently Asked Questions about DHK07.0143P5 Four-Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
As standard production, CHG Bearing subjects DHK07.0143P5 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.
Quality starts with raw material selection: CHG Bearing crafts DHK07.0143P5 inner and outer rings from high-purity High-Quality Chrome Steel (GCr15/100Cr6). Our raw billets undergo vacuum degassing and secondary ESR (electroslag remelting) processes to drastically eliminate non-metallic sulfide and oxide inclusions, elevating subsurface contact fatigue resistance.
Engineered according to international ISO boundary plans, CHG Bearing supplies DHK07.0143P5 with a precision bore diameter (d) of 355.6 mm, an outside diameter (D) of 488.95 mm, and a nominal ring width (B) of 317.5 mm. This configuration yields an effective cross-sectional wall thickness of 66.7 mm and an envelope ratio (D/d) of 1.37, delivering compact rigidity for OEM machinery housings.
To safeguard CHG Bearing DHK07.0143P5 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (355.6 mm x 488.95 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
