NU20/500E/P5 720 mm 500 mm 128 mm 553 mm Frequently Asked Questions about NU20/500E/P5 Single Row Cylindrical Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Model NU20/500E/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 500 mm) and steep thermal gradients between inner and outer rings.
Standard batches of CHG Bearing NU20/500E/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.
Sourcing NU20/500E/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.
Yes, 100% of NU20/500E/P5 Single Row Cylindrical Roller Bearings leaving CHG Bearing production lines are subjected to multi-frequency Anderometer sound testing. All units satisfy baseline Z1V1 levels, with dedicated quiet-running electric motor quality (EMQ) lots certified to Z2V2 and Z3V3 standards for silent machinery integration.
