NU30/530R 780 mm 530 mm 185 mm 589 mm Frequently Asked Questions about NU30/530R Single Row Cylindrical Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Built for demanding industrial environments, the NU30/530R Single Row Cylindrical Roller Bearings by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
Engineered according to international ISO boundary plans, CHG Bearing supplies NU30/530R with a precision bore diameter (d) of 530 mm, an outside diameter (D) of 780 mm, and a nominal ring width (B) of 185 mm. This configuration yields an effective cross-sectional wall thickness of 125.0 mm and an envelope ratio (D/d) of 1.47, delivering compact rigidity for OEM machinery housings.
For international ocean and air freight, CHG Bearing packs NU30/530R with industrial VCI anti-corrosion barrier wrapping, sealed polybags, individual cartons, and fumigated ocean-worthy wooden crates. This multi-layer barrier guarantees rust-free storage for a minimum shelf life of 24 to 36 months.
The Open Type engineered for NU30/530R 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.
