Bearing units are a pre-assembled selection of ready to mount plummer blocks, 2 & 4 bolt flanged and take-up units, cost-effective and consist of a bearing and cast-iron housing with either grub screw shaft locking or an eccentric shaft locking collar. Bearing units have a self-aligning feature due to their spherical outer diameters within the bearing housing which allows for misalignment. Food quality stainless steel are also available.
