Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Every production batch of CHG Bearing 27FC19120/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.
To match diverse operational dynamics, CHG Bearing supplies 27FC19120/P5 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies 27FC19120/P5 with a precision bore diameter (d) of 135 mm, an outside diameter (D) of 188 mm, and a nominal ring width (B) of 121 mm. This configuration yields an effective cross-sectional wall thickness of 26.5 mm and an envelope ratio (D/d) of 1.39, delivering compact rigidity for OEM machinery housings.
Standard batches of CHG Bearing 27FC19120/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.
