Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Every production batch of CHG Bearing 76FC52290/P5 Four-Row Cylindrical Roller Bearings comes with complete traceability. Upon shipment, CHG Bearing can provide EN 10204 3.1 Material Test Reports (MTR), Certificates of Conformity (CoC), spectral chemical composition analysis, and dimensional inspection sheets.
Engineered according to international ISO boundary plans, CHG Bearing supplies 76FC52290/P5 with a precision bore diameter (d) of 380 mm, an outside diameter (D) of 520 mm, and a nominal ring width (B) of 290 mm. This configuration yields an effective cross-sectional wall thickness of 70.0 mm and an envelope ratio (D/d) of 1.37, delivering compact rigidity for OEM machinery housings.
Quality starts with raw material selection: CHG Bearing crafts 76FC52290/P5 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.
Standard batches of CHG Bearing 76FC52290/P5 conform strictly to ISO Class Normal (ABEC-1). For high-precision machine tool spindles, gearboxes, or robotics requiring tighter runouts, CHG Bearing can provide custom batches graded to ISO Class 6 (P6/ABEC-3) or ISO Class 5 (P5/ABEC-5) with 100% micrometer verification.
