Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To safeguard CHG Bearing NU252 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (260 mm x 480 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Sourcing NU252 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.
Model NU252 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 260 mm) and steep thermal gradients between inner and outer rings.
For international ocean and air freight, CHG Bearing packs NU252 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.
