Find key technical answers regarding dimensions, specifications, and replacement options for this model.
In its sealed configuration (Open Type), CHG Bearing pre-charges NU29/500 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.
To match diverse operational dynamics, CHG Bearing supplies NU29/500 with multiple cage configurations: high-strength pressed steel ribbon cages for standard duty, solid machined brass cages (M/CA) for heavy vibration and shock loads, or lightweight glass-fiber reinforced polyamide cages (TN9/TVP) for high acceleration and ultra-low noise.
Engineered according to international ISO boundary plans, CHG Bearing supplies NU29/500 with a precision bore diameter (d) of 500 mm, an outside diameter (D) of 670 mm, and a nominal ring width (B) of 100 mm. This configuration yields an effective cross-sectional wall thickness of 85.0 mm and an envelope ratio (D/d) of 1.34, delivering compact rigidity for OEM machinery housings.
As standard production, CHG Bearing subjects NU29/500 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.
