4 Bolt Flanged Bearings

Bearings Housed & Flanged Bearings

Browse our comprehensive range of 4 bolt flanged bearings, designed for demanding industrial and agricultural applications. These complete bearing units feature a pre-drilled cast iron housing with four mounting holes, a grease nipple for easy maintenance, and include a high-quality bearing insert with dual grub screws for secure shaft mounting. Available in bore sizes from 12mm up to 140mm, our selection includes trusted brands like FK, Dunlop, FS, FSB, and RHP. The modular design allows for cost-effective maintenance as the bearing insert can be replaced separately when worn.

Whether you need standard UCF or heavy-duty UCFX series bearings, our extensive stock ensures quick delivery from our UK warehouse.
