Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Built for demanding industrial environments, the 131.30.3150.12K 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 131.30.3150.12K 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.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for 131.30.3150.12K. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
To extend the trouble-free lifespan of CHG Bearing 131.30.3150.12K, preventive maintenance routines should monitor operating housing temperature (normally maintaining below 70°C) and conduct regular vibration FFT analysis to identify early raceway micro-pitting before unexpected line halts occur.
