719/530 710 mm 530 mm 82 mm Frequently Asked Questions about 719/530 Angular Contact Ball Bearings（718 / 719 SERIES）
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies 719/530 with a precision bore diameter (d) of 530 mm, an outside diameter (D) of 710 mm, and a nominal ring width (B) of 82 mm. This configuration yields an effective cross-sectional wall thickness of 90.0 mm and an envelope ratio (D/d) of 1.34, delivering compact rigidity for OEM machinery housings.
Absolutely. The CHG Bearing 719/530 Angular Contact Ball Bearings（718 / 719 SERIES） is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 719/530, FAG 719/530, NSK 719/530. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Each 719/530 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 (530 mm bore side) ensures perfect planar contact without edge binding.
To ensure optimum performance of CHG Bearing 719/530 Angular Contact Ball Bearings（718 / 719 SERIES） under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 530 mm bore. For the 710 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
