45T615020D-1 500 mm 305 mm Frequently Asked Questions about 45T615020D-1 Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
When fitting 45T615020D-1 over a 305 mm shaft, CHG Bearing strictly recommends uniform induction heating (controlled between 90°C and 110°C) or precision hydraulic press sleeves. Under no circumstances should direct impact blows be struck against the rings or cage, as shock loads cause brinelling indents and premature spalling.
As standard production, CHG Bearing subjects 45T615020D-1 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.
Each 45T615020D-1 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 (305 mm bore side) ensures perfect planar contact without edge binding.
Engineered according to international ISO boundary plans, CHG Bearing supplies 45T615020D-1 with a precision bore diameter (d) of 305 mm, an outside diameter (D) of 500 mm, and a nominal ring width (B) of 200 mm. This configuration yields an effective cross-sectional wall thickness of 97.5 mm and an envelope ratio (D/d) of 1.64, delivering compact rigidity for OEM machinery housings.
