NNU4096K/W33P5 700 mm 480 mm 533 mm 218 mm Frequently Asked Questions about NNU4096K/W33P5 Double Row Cylindrical Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To match diverse operational dynamics, CHG Bearing supplies NNU4096K/W33P5 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 NNU4096K/W33P5 with a precision bore diameter (d) of 480 mm, an outside diameter (D) of 700 mm, and a nominal ring width (B) of 218 mm. This configuration yields an effective cross-sectional wall thickness of 110.0 mm and an envelope ratio (D/d) of 1.46, delivering compact rigidity for OEM machinery housings.
To ensure optimum performance of CHG Bearing NNU4096K/W33P5 Double Row Cylindrical Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 480 mm bore. For the 700 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Quality starts with raw material selection: CHG Bearing crafts NNU4096K/W33P5 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.
