NN 3017 KTN9/SPVS019 130 mm 85 mm 34 mm Frequently Asked Questions about NN 3017 KTN9/SPVS019 Super-Precision Cylindrical Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
When fitting NN 3017 KTN9/SPVS019 over a 85 mm shaft, CHG Bearing strictly recommends uniform induction heating (controlled between 90°C and 110°C) or precision hydraulic press sleeves. Under no circumstances should direct impact blows be struck against the rings or cage, as shock loads cause brinelling indents and premature spalling.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for NN 3017 KTN9/SPVS019, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
To ensure optimum performance of CHG Bearing NN 3017 KTN9/SPVS019 Super-Precision Cylindrical Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 85 mm bore. For the 130 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Every production batch of CHG Bearing NN 3017 KTN9/SPVS019 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.
