Find key technical answers regarding dimensions, specifications, and replacement options for this model.
In its sealed configuration (Open Type), CHG Bearing pre-charges 46T30221JR/133 with premium wide-temperature lithium-complex or polyurea grease, calibrated to a 30%–35% cavity volume ratio. For open-type variants, synthetic PAO or refined mineral lubricating oils with appropriate EP (Extreme Pressure) additives should be circulated.
Engineered according to international ISO boundary plans, CHG Bearing supplies 46T30221JR/133 with a precision bore diameter (d) of 105 mm, an outside diameter (D) of 225 mm, and a nominal ring width (B) of 170 mm. This configuration yields an effective cross-sectional wall thickness of 60.0 mm and an envelope ratio (D/d) of 2.14, delivering compact rigidity for OEM machinery housings.
As standard production, CHG Bearing subjects 46T30221JR/133 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.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for 46T30221JR/133. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
