Find key technical answers regarding dimensions, specifications, and replacement options for this model.
As standard production, CHG Bearing subjects 021.40.1400 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies 021.40.1400 with a precision bore diameter (d) of 1224 mm, an outside diameter (D) of 1576 mm, and a nominal ring width (B) of 160 mm. This configuration yields an effective cross-sectional wall thickness of 176.0 mm and an envelope ratio (D/d) of 1.29, delivering compact rigidity for OEM machinery housings.
Standard batches of CHG Bearing 021.40.1400 conform strictly to ISO Class Normal (ABEC-1). For high-precision machine tool spindles, gearboxes, or robotics requiring tighter runouts, CHG Bearing can provide custom batches graded to ISO Class 6 (P6/ABEC-3) or ISO Class 5 (P5/ABEC-5) with 100% micrometer verification.
Model 021.40.1400 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 1224 mm) and steep thermal gradients between inner and outer rings.
