32948X 320 mm 239.8 mm 51 mm Frequently Asked Questions about 32948X Single Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The Open Type engineered for 32948X by CHG Bearing utilizes precision non-contact metal shields or reinforced NBR/FKM contact lip seals. This barrier prevents particulate ingress, washdown fluids, and abrasive dust from reaching the raceways while eliminating grease leakage under centrifugal forces.
When fitting 32948X over a 239.8 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.
Absolutely. The CHG Bearing 32948X Single Row Tapered Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 32948X, FAG 32948X, NSK 32948X. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
As standard production, CHG Bearing subjects 32948X 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.
