Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Built for demanding industrial environments, the 36.9*46.18 Tapered Rollers by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
Absolutely. The CHG Bearing 36.9*46.18 Tapered Rollers is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 36.9*46.18, FAG 36.9*46.18, NSK 36.9*46.18. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
To ensure optimum performance of CHG Bearing 36.9*46.18 Tapered Rollers under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the mm bore. For the 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 36.9*46.18 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.
