Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Quality starts with raw material selection: CHG Bearing crafts 021.50.2240 inner and outer rings from high-purity High-Quality Chrome Steel (GCr15/100Cr6). Our raw billets undergo vacuum degassing and secondary ESR (electroslag remelting) processes to drastically eliminate non-metallic sulfide and oxide inclusions, elevating subsurface contact fatigue resistance.
Engineered according to international ISO boundary plans, CHG Bearing supplies 021.50.2240 with a precision bore diameter (d) of 2025 mm, an outside diameter (D) of 2455 mm, and a nominal ring width (B) of 190 mm. This configuration yields an effective cross-sectional wall thickness of 215.0 mm and an envelope ratio (D/d) of 1.21, delivering compact rigidity for OEM machinery housings.
Absolutely. The CHG Bearing 021.50.2240 Double-Row Ball Slewing Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 021.50.2240, FAG 021.50.2240, NSK 021.50.2240. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
As standard production, CHG Bearing subjects 021.50.2240 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.
