Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies 130.50.3150.12K1 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.
Quality starts with raw material selection: CHG Bearing crafts 130.50.3150.12K1 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.
To match diverse operational dynamics, CHG Bearing supplies 130.50.3150.12K1 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.
As standard production, CHG Bearing subjects 130.50.3150.12K1 to precision bainite or martensite quenching, offering dimensional stability up to 120°C (248°F). For high-heat processing equipment, CHG Bearing also supplies custom S0 (150°C), S1 (200°C), or S2 (250°C) stabilization heat treatments upon request to prevent residual austenite transformation.
