980811NT Forklift Mast Roller Bearing – 55×119.2×34 mm, Heavy Duty Chrome Steel

The 980811NT Forklift Mast Roller Bearing is a specialized, high-capacity bearing engineered to manage the intense radial loads generated by heavy lifting equipment. Measuring 55 mm (ID) × 119.2 mm (OD) × 34 mm (Width) and forged from premium Chrome Steel, it fixes and reduces the friction coefficient of load-bearing components along the forklift's mast. Equipped with heavy-duty rubber seals (2RS) to protect against industrial dust and debris, this bearing significantly extends the service life and operational smoothness of 5-10 ton forklifts. We offer OEM/ODM services, competitive wholesale pricing, and reliable global fulfillment.
