Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Model 133.35.2956.03K2 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 2751 mm) and steep thermal gradients between inner and outer rings.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for 133.35.2956.03K2. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
Engineered according to international ISO boundary plans, CHG Bearing supplies 133.35.2956.03K2 with a precision bore diameter (d) of 2751 mm, an outside diameter (D) of 3215 mm, and a nominal ring width (B) of 200 mm. This configuration yields an effective cross-sectional wall thickness of 232.0 mm and an envelope ratio (D/d) of 1.17, delivering compact rigidity for OEM machinery housings.
As standard production, CHG Bearing subjects 133.35.2956.03K2 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.
