Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Absolutely. The CHG Bearing 47.4*68.12 Tapered Rollers is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 47.4*68.12, FAG 47.4*68.12, NSK 47.4*68.12. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for 47.4*68.12, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
The Open Type engineered for 47.4*68.12 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.
Beyond standard alloy steel, CHG Bearing can customize the 47.4*68.12 Tapered Rollers using AISI 440C stainless steel, black oxide coating, zinc-nickel plating, or hybrid ceramic (Si3N4) balls for applications involving chemical exposure, marine salt fog, or galvanic current hazards.
