The bearings are structurally engineered to be capable of supporting great axial, radial, and moment forces. Whereas, LRQ series consists of a single row of four point contact ball bearings. HULR series consists of two rows of contact ball bearings. Mast rollers are available in two fitting series, HULR and LRQ. It is an extremely important component of the mast as it enables the vertical movement of the fork carriers, while maintaining its structural rigidity. The mast rollers transforms the forces and moments that derive from the fork carrier, into the mast and into the frame. The mast is located at the frontal part of a forklift and its purpose is to raise and lower loads. Forklift Mast Rollers are generally found running between the inner masts and four lift mast rollers run between the outer and the inner masts.
