Find key technical answers regarding dimensions, specifications, and replacement options for this model.
As standard production, CHG Bearing subjects N1920/P5 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.
The CHG Bearing N1920/P5 is rated for limiting speeds up to standard rated RPM under forced oil-mist or circulating oil lubrication regimes. When lubricated with factory-filled synthetic high-speed grease, safe continuous velocity is maintained at approximately 75% to 85% of the maximum nominal limit, preventing thermal runaway.
Every production batch of CHG Bearing N1920/P5 Single 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 N1920/P5 with a precision bore diameter (d) of 100 mm, an outside diameter (D) of 140 mm, and a nominal ring width (B) of 20 mm. This configuration yields an effective cross-sectional wall thickness of 20.0 mm and an envelope ratio (D/d) of 1.4, delivering compact rigidity for OEM machinery housings.
