Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Every production batch of CHG Bearing N068 Single Row Cylindrical Roller Bearings comes with complete traceability. Upon shipment, CHG Bearing can provide EN 10204 3.1 Material Test Reports (MTR), Certificates of Conformity (CoC), spectral chemical composition analysis, and dimensional inspection sheets.
Engineered according to international ISO boundary plans, CHG Bearing supplies N068 with a precision bore diameter (d) of 340 mm, an outside diameter (D) of 520 mm, and a nominal ring width (B) of 57 mm. This configuration yields an effective cross-sectional wall thickness of 90.0 mm and an envelope ratio (D/d) of 1.53, delivering compact rigidity for OEM machinery housings.
Built for demanding industrial environments, the N068 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.
Model N068 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 340 mm) and steep thermal gradients between inner and outer rings.
