Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies 131.50.3150.12K1 with a precision bore diameter (d) of 2868 mm, an outside diameter (D) of 3432 mm, and a nominal ring width (B) of 270 mm. This configuration yields an effective cross-sectional wall thickness of 282.0 mm and an envelope ratio (D/d) of 1.2, delivering compact rigidity for OEM machinery housings.
Sourcing 131.50.3150.12K1 directly from CHG Bearing eliminates intermediate brokerage markups while granting you factory-direct engineering backup, rigorous ISO-certified quality assurance, competitive volume wholesale pricing, and dependable supply chain stability for Three-row Cylindrical Roller Slewing Bearings.
Built for demanding industrial environments, the 131.50.3150.12K1 Three-row Cylindrical Roller Slewing Bearings 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.
Quality starts with raw material selection: CHG Bearing crafts 131.50.3150.12K1 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.
