996000/99100 254 mm 152.4 mm Frequently Asked Questions about 996000/99100 Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies 996000/99100 with a precision bore diameter (d) of 152.4 mm, an outside diameter (D) of 254 mm, and a nominal ring width (B) of 133.35 mm. This configuration yields an effective cross-sectional wall thickness of 50.8 mm and an envelope ratio (D/d) of 1.67, delivering compact rigidity for OEM machinery housings.
Quality starts with raw material selection: CHG Bearing crafts 996000/99100 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.
To ensure optimum performance of CHG Bearing 996000/99100 Double Row Tapered Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 152.4 mm bore. For the 254 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Following standard ISO 281 fatigue calculation guidelines, the nominal rating life (L10) of CHG Bearing 996000/99100 correlates its dynamic capacity (standard dynamic) with equivalent dynamic loads. In controlled industrial settings with proper contamination-free filtration, field data confirms continuous operational longevity exceeding 20,000 to 50,000 service hours.
