453/530 870 mm 530 mm Frequently Asked Questions about 453/530 Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies 453/530 with a precision bore diameter (d) of 530 mm, an outside diameter (D) of 870 mm, and a nominal ring width (B) of 272 mm. This configuration yields an effective cross-sectional wall thickness of 170.0 mm and an envelope ratio (D/d) of 1.64, delivering compact rigidity for OEM machinery housings.
Model 453/530 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 530 mm) and steep thermal gradients between inner and outer rings.
The Open Type engineered for 453/530 by CHG Bearing utilizes precision non-contact metal shields or reinforced NBR/FKM contact lip seals. This barrier prevents particulate ingress, washdown fluids, and abrasive dust from reaching the raceways while eliminating grease leakage under centrifugal forces.
To ensure optimum performance of CHG Bearing 453/530 Double Row Tapered Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 530 mm bore. For the 870 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
