Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Model NU3030 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 150 mm) and steep thermal gradients between inner and outer rings.
Standard batches of CHG Bearing NU3030 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.
The Open Type engineered for NU3030 by CHG Bearing utilizes precision non-contact metal shields or reinforced NBR/FKM contact lip seals. This barrier prevents particulate ingress, washdown fluids, and abrasive dust from reaching the raceways while eliminating grease leakage under centrifugal forces.
Engineered according to international ISO boundary plans, CHG Bearing supplies NU3030 with a precision bore diameter (d) of 150 mm, an outside diameter (D) of 225 mm, and a nominal ring width (B) of 56 mm. This configuration yields an effective cross-sectional wall thickness of 37.5 mm and an envelope ratio (D/d) of 1.5, delivering compact rigidity for OEM machinery housings.
