EE982051/982901D 736.6 mm 520.7 mm Frequently Asked Questions about EE982051/982901D Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Absolutely. The CHG Bearing EE982051/982901D Double Row Tapered Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF EE982051/982901D, FAG EE982051/982901D, NSK EE982051/982901D. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
When fitting EE982051/982901D over a 520.7 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.
Quality starts with raw material selection: CHG Bearing crafts EE982051/982901D 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.
As standard production, CHG Bearing subjects EE982051/982901D to precision bainite or martensite quenching, offering dimensional stability up to 120°C (248°F). For high-heat processing equipment, CHG Bearing also supplies custom S0 (150°C), S1 (200°C), or S2 (250°C) stabilization heat treatments upon request to prevent residual austenite transformation.
