020.50.2240 2455 mm 2025 mm 190 mm 2091 mm 2389 mm Frequently Asked Questions about 020.50.2240 Double-Row Ball Slewing Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Model 020.50.2240 is manufactured by CHG Bearing in standard Normal clearance (CN) for ambient temperature transmission, and C3 or C4 clearance for heavy duty applications. C3 clearance compensates for radial shrinkage caused by tight shaft press-fits (bore 2025 mm) and steep thermal gradients between inner and outer rings.
Quality starts with raw material selection: CHG Bearing crafts 020.50.2240 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.
Beyond standard alloy steel, CHG Bearing can customize the 020.50.2240 Double-Row Ball Slewing Bearings using AISI 440C stainless steel, black oxide coating, zinc-nickel plating, or hybrid ceramic (Si3N4) balls for applications involving chemical exposure, marine salt fog, or galvanic current hazards.
Engineered according to international ISO boundary plans, CHG Bearing supplies 020.50.2240 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.
