This NSK unit pairs a cast iron 4-bolt flange housing with a spherical roller insert bearing, making it a front-mounting solution for rotating shafts that see moderate radial and axial load. It bolts to metal structures or masonry with the shaft running perpendicular to the mounting face, and it installs and aligns quickly on industrial drives.
The UKFS prefix points to a 4-bolt flange housing supplied together with its insert bearing. The digits after it give the shaft size: UKFS311D1 fits a 55 mm shaft, and HE2311XY is the matching insert bearing. D1 and XY cover sealing and insert variants, so reading the code correctly is what lets you order the exact replacement.
You will find these units on conveyors, mixers, mills, pumps and industrial fans, including food, cement, chemical and aggregate processing operations. The four-bolt flange fixes to steelwork or masonry, and with the right seal choice the unit handles dusty and humid conditions.
Selection comes down to shaft diameter, radial and axial load, and where the unit will sit. Match the insert seal to dust, water or chemical exposure. When mounting, align the flange and tighten bolts in a cross pattern so the housing is not distorted, then lubricate per the insert type and verify axial clearance. Good alignment and lubrication are what keep the bearing running.
NSK UKFS housings interchange with units from other makers when the flange standard and shaft diameter line up. Match on dimensions and load capacity rather than the code alone, and confirm measurements before you replace. Send us another brand's code and we will quote it and point out the compatible option.

Frequently asked questions
- What does UKFS311D1 tell me?
- UKFS means a 4-bolt flange housing with insert bearing. The 311 gives the shaft size, 55 mm. D1 is a sealing variant, and HE2311XY is the insert bearing that goes with it. Send that code and we can quote the exact unit.
- How do I pick the sealing?
- It depends on where the unit runs. Dry dust may only need a standard seal, while humidity or washdown calls for a reinforced one. If chemicals are present, ask about special materials. The right seal keeps contamination out of the bearing.
- Can this NSK unit replace another brand's housing?
- Yes, when flange dimensions, shaft diameter and load capacity match. Interchange is based on standardized measurements. Send the original code and we will quote the compatible NSK unit.
