Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Beyond standard alloy steel, CHG Bearing can customize the NU1928/P5 Single Row Cylindrical Roller Bearings using AISI 440C stainless steel, black oxide coating, zinc-nickel plating, or hybrid ceramic (Si3N4) balls for applications involving chemical exposure, marine salt fog, or galvanic current hazards.
Engineered according to international ISO boundary plans, CHG Bearing supplies NU1928/P5 with a precision bore diameter (d) of 140 mm, an outside diameter (D) of 190 mm, and a nominal ring width (B) of 24 mm. This configuration yields an effective cross-sectional wall thickness of 25.0 mm and an envelope ratio (D/d) of 1.36, delivering compact rigidity for OEM machinery housings.
The CHG Bearing NU1928/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.
Following standard ISO 281 fatigue calculation guidelines, the nominal rating life (L10) of CHG Bearing NU1928/P5 correlates its dynamic capacity (standard dynamic) with equivalent dynamic loads. In controlled industrial settings with proper contamination-free filtration, field data confirms continuous operational longevity exceeding 20,000 to 50,000 service hours.
