GQZ NU308ECP Single Row Cylindrical Roller Bearing 40mm Bore Enhanced EC Design Solid Brass Cage Industrial Rolling Bearing

The NU308ECP single row cylindrical roller bearing features separable construction. The outer ring has no ribs, allowing axial displacement between inner and outer rings. Adopting EC optimized internal structure and solid machined brass cage, the bearing delivers excellent heavy radial load performance and stable operation.

It is commonly installed in gearboxes, heavy conveyors and engineering machinery subjected to substantial radial loads.
