462/630 920 mm 630 mm Frequently Asked Questions about 462/630 Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To ensure optimum performance of CHG Bearing 462/630 Double Row Tapered Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 630 mm bore. For the 920 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 462/630 with a precision bore diameter (d) of 630 mm, an outside diameter (D) of 920 mm, and a nominal ring width (B) of 212 mm. This configuration yields an effective cross-sectional wall thickness of 145.0 mm and an envelope ratio (D/d) of 1.46, delivering compact rigidity for OEM machinery housings.
Yes, 100% of 462/630 Double Row Tapered Roller Bearings leaving CHG Bearing production lines are subjected to multi-frequency Anderometer sound testing. All units satisfy baseline Z1V1 levels, with dedicated quiet-running electric motor quality (EMQ) lots certified to Z2V2 and Z3V3 standards for silent machinery integration.
Each 462/630 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 (630 mm bore side) ensures perfect planar contact without edge binding.
