NA82576/82932D 236.538 mm 146.05 mm Frequently Asked Questions about NA82576/82932D Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To ensure optimum performance of CHG Bearing NA82576/82932D Double Row Tapered Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 146.05 mm bore. For the 236.538 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Quality starts with raw material selection: CHG Bearing crafts NA82576/82932D 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.
Every production batch of CHG Bearing NA82576/82932D Double Row Tapered 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.
Absolutely. The CHG Bearing NA82576/82932D Double Row Tapered Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF NA82576/82932D, FAG NA82576/82932D, NSK NA82576/82932D. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
