Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies NN 3006 KTN/VQ497 with a precision bore diameter (d) of 30 mm, an outside diameter (D) of 55 mm, and a nominal ring width (B) of 19 mm. This configuration yields an effective cross-sectional wall thickness of 12.5 mm and an envelope ratio (D/d) of 1.83, delivering compact rigidity for OEM machinery housings.
Built for demanding industrial environments, the NN 3006 KTN/VQ497 Super-Precision 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.
In its sealed configuration (Open Type), CHG Bearing pre-charges NN 3006 KTN/VQ497 with premium wide-temperature lithium-complex or polyurea grease, calibrated to a 30%–35% cavity volume ratio. For open-type variants, synthetic PAO or refined mineral lubricating oils with appropriate EP (Extreme Pressure) additives should be circulated.
Every production batch of CHG Bearing NN 3006 KTN/VQ497 Super-Precision 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.
