45T6156A 560 mm 305.069 mm Frequently Asked Questions about 45T6156A Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each 45T6156A 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 (305.069 mm bore side) ensures perfect planar contact without edge binding.
To ensure optimum performance of CHG Bearing 45T6156A Double Row Tapered Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 305.069 mm bore. For the 560 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Engineered according to international ISO boundary plans, CHG Bearing supplies 45T6156A with a precision bore diameter (d) of 305.069 mm, an outside diameter (D) of 560 mm, and a nominal ring width (B) of 200 mm. This configuration yields an effective cross-sectional wall thickness of 127.5 mm and an envelope ratio (D/d) of 1.84, delivering compact rigidity for OEM machinery housings.
Model 45T6156A 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 305.069 mm) and steep thermal gradients between inner and outer rings.
