Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Absolutely. The CHG Bearing 719/500 Angular Contact Ball Bearings（718 / 719 SERIES） is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 719/500, FAG 719/500, NSK 719/500. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for 719/500, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
Each 719/500 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 (500 mm bore side) ensures perfect planar contact without edge binding.
To safeguard CHG Bearing 719/500 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (500 mm x 670 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
