Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To safeguard CHG Bearing 024.30.900 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (758 mm x 1042 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
As standard production, CHG Bearing subjects 024.30.900 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.
The Open Type engineered for 024.30.900 by CHG Bearing utilizes precision non-contact metal shields or reinforced NBR/FKM contact lip seals. This barrier prevents particulate ingress, washdown fluids, and abrasive dust from reaching the raceways while eliminating grease leakage under centrifugal forces.
Absolutely. The CHG Bearing 024.30.900 Double-Row Ball Slewing Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 024.30.900, FAG 024.30.900, NSK 024.30.900. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
