NU260 540 mm 300 mm 85 mm 364 mm Frequently Asked Questions about NU260 Single Row Cylindrical Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Built for demanding industrial environments, the NU260 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.
For international ocean and air freight, CHG Bearing packs NU260 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies NU260 with a precision bore diameter (d) of 300 mm, an outside diameter (D) of 540 mm, and a nominal ring width (B) of 85 mm. This configuration yields an effective cross-sectional wall thickness of 120.0 mm and an envelope ratio (D/d) of 1.8, delivering compact rigidity for OEM machinery housings.
Quality starts with raw material selection: CHG Bearing crafts NU260 inner and outer rings from high-purity High-Quality Chrome Steel (GCr15/100Cr6). Our raw billets undergo vacuum degassing and secondary ESR (electroslag remelting) processes to drastically eliminate non-metallic sulfide and oxide inclusions, elevating subsurface contact fatigue resistance.
