Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To match diverse operational dynamics, CHG Bearing supplies NU1956/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.
Sourcing NU1956/P5 directly from CHG Bearing eliminates intermediate brokerage markups while granting you factory-direct engineering backup, rigorous ISO-certified quality assurance, competitive volume wholesale pricing, and dependable supply chain stability for Single Row Cylindrical Roller Bearings.
Engineered according to international ISO boundary plans, CHG Bearing supplies NU1956/P5 with a precision bore diameter (d) of 280 mm, an outside diameter (D) of 380 mm, and a nominal ring width (B) of 46 mm. This configuration yields an effective cross-sectional wall thickness of 50.0 mm and an envelope ratio (D/d) of 1.36, delivering compact rigidity for OEM machinery housings.
Model NU1956/P5 is manufactured by CHG Bearing in standard Normal clearance (CN) for ambient temperature transmission, and C3 or C4 clearance for heavy duty applications. C3 clearance compensates for radial shrinkage caused by tight shaft press-fits (bore 280 mm) and steep thermal gradients between inner and outer rings.
