The eco-friendly series of spherical roller bearings with diamond-shaped flanges features an eccentric ring locking mechanism. Manufactured using environmentally friendly materials and clean production processes, they contain no harmful residues and meet the stringent hygiene and environmental requirements of the food, pharmaceutical and light industrial sectors. The compact design of the diamond-shaped flange housing makes it suitable for mounting on equipment end faces where space is limited, ensuring simple installation and secure positioning. The eccentric ring provides reliable locking and facilitates easy disassembly and assembly, effectively preventing loosening during operation. The bearings offer excellent self-aligning performance, compensating for installation and alignment errors. They operate smoothly with low noise and a long service life, and are widely used in transmission components requiring high cleanliness and operational stability, such as automated conveyors, food processing machinery and environmental protection equipment.
