Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for 718/530, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
Built for demanding industrial environments, the 718/530 Angular Contact Ball Bearings（718 / 719 SERIES） by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
Each 718/530 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.
Every production batch of CHG Bearing 718/530 Angular Contact Ball Bearings（718 / 719 SERIES） comes with complete traceability. Upon shipment, CHG Bearing can provide EN 10204 3.1 Material Test Reports (MTR), Certificates of Conformity (CoC), spectral chemical composition analysis, and dimensional inspection sheets.
