Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for NN 3036 K/SPW33VS019, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
Every production batch of CHG Bearing NN 3036 K/SPW33VS019 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies NN 3036 K/SPW33VS019 with a precision bore diameter (d) of 180 mm, an outside diameter (D) of 280 mm, and a nominal ring width (B) of 74 mm. This configuration yields an effective cross-sectional wall thickness of 50.0 mm and an envelope ratio (D/d) of 1.56, delivering compact rigidity for OEM machinery housings.
Quality starts with raw material selection: CHG Bearing crafts NN 3036 K/SPW33VS019 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.
