UKF211+H2311 Square Flange Bearing Unit 50mm Four Bolt Flanged Taper Bore Insert Bearing With H2311 Adapter Sleeve

• UKF211+H2311 is a complete four-bolt square flanged mounted bearing unit, composed of UK211 tapered bore insert bearing, F211 cast iron flange housing and H2311 adapter sleeve. Different from set screw locking bearings, this unit adopts sleeve locking structure, which enables tool-free installation on smooth shafts without damaging the shaft surface. Equipped with double-lip rubber seals and self-aligning function, it effectively compensates minor shaft misalignment, ensuring stable, low-noise and long-lasting operation for various industrial transmission equipment.
