Product Description
Data Sheet

Inch Series Double Row Tapered Roller Bearings | Built for Extreme Load & High-Temperature Industrial Applications

Engineered for metallurgical equipment, port machinery, and heavy-duty OEM systems requiring 200~350°C heat resistance, P0/P6/P5/P4-grade precision, and 30%+ higher load capacity than standard bearings.

When your machinery operates under extreme stress—whether from 300-ton loads in steel mills or relentless shock impacts in port cranes—Inch Series Double Row Tapered Roller Bearings deliver unmatched durability. Designed with double-row tapered rollers and optimized raceways, these bearings distribute heavy radial and axial loads evenly, reducing wear and extending equipment lifespan.
