619/950 1250 mm 950 mm 132 mm Frequently Asked Questions about 619/950 Deep Groove Ball Bearings（618 / 619 SERIES）
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To safeguard CHG Bearing 619/950 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (950 mm x 1250 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Absolutely. The CHG Bearing 619/950 Deep Groove Ball Bearings（618 / 619 SERIES） is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 619/950, FAG 619/950, NSK 619/950. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Each 619/950 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 (950 mm bore side) ensures perfect planar contact without edge binding.
As standard production, CHG Bearing subjects 619/950 to precision bainite or martensite quenching, offering dimensional stability up to 120°C (248°F). For high-heat processing equipment, CHG Bearing also supplies custom S0 (150°C), S1 (200°C), or S2 (250°C) stabilization heat treatments upon request to prevent residual austenite transformation.
