N338/P5 400 mm 190 mm 345 mm 78 mm Frequently Asked Questions about N338/P5 Single Row Cylindrical Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Beyond standard alloy steel, CHG Bearing can customize the N338/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.
To match diverse operational dynamics, CHG Bearing supplies N338/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.
Standard batches of CHG Bearing N338/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.
Engineered according to international ISO boundary plans, CHG Bearing supplies N338/P5 with a precision bore diameter (d) of 190 mm, an outside diameter (D) of 400 mm, and a nominal ring width (B) of 78 mm. This configuration yields an effective cross-sectional wall thickness of 105.0 mm and an envelope ratio (D/d) of 2.11, delivering compact rigidity for OEM machinery housings.
