46T846219 620 mm 420 mm Frequently Asked Questions about 46T846219 Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each 46T846219 produced in CHG Bearing manufacturing facilities features accurately profiled corner chamfers complying with DIN 5412 / ISO standard corner radii. When designing mating shafts and housing shoulders, machining an undercut or fillet radius strictly within the inner ring clearance limit (420 mm bore side) ensures perfect planar contact without edge binding.
As standard production, CHG Bearing subjects 46T846219 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies 46T846219 with a precision bore diameter (d) of 420 mm, an outside diameter (D) of 620 mm, and a nominal ring width (B) of 190 mm. This configuration yields an effective cross-sectional wall thickness of 100.0 mm and an envelope ratio (D/d) of 1.48, delivering compact rigidity for OEM machinery housings.
To safeguard CHG Bearing 46T846219 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (420 mm x 620 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
