The NSK UKFS is a four-bolt flange mounted unit that pairs a cast iron housing with a Y-bearing insert. Bolted to a flat surface, it supports a rotating shaft while the insert's spherical seat lets the bearing align itself inside the housing. This makes it a practical choice for conveying, mixing and power transmission equipment where mounting needs to stay simple but the support has to be rigid.
Reading the code tells you what you are ordering. UKFS points to the square four-bolt flange housing with a UK series insert. The digits that follow, such as 308, 309 or 313 in UKFS308D1, UKFS309D1 and UKFS313D1, step up with shaft diameter. The D1 suffix covers sealing or insert design variants. An HS reference, for instance HS2308X or HS2309X, identifies the adapter sleeve that locks the bearing onto the shaft. Ordering the housing, insert and sleeve correctly starts with these three elements.
Typical duty includes belt and roller conveyors, mixers, mills, screens and other process equipment, plus road machinery, aggregate plants and ventilation systems. Because the shaft does not pass through the unit, it works well as a front support where a firm fixing point is required. The four bolts spread the load into sheet metal or steel frames, and the insert absorbs small amounts of shaft misalignment on its own.
Selection comes down to shaft diameter, the nature of the load and where the unit will sit. The insert seal determines how well dust and moisture are kept out, so a dirtier environment calls for tighter sealing. Internal clearance and the lubricant must suit the running speed and temperature. At installation, seat the flange flat and tighten the bolts evenly to avoid distorting the housing; alignment with the shaft is handled by the spherical seat clearance.
Interchange is possible with units from other manufacturers that share the same flange nomenclature and shaft diameter. Flange dimensions, hole spacing and shaft size are the figures that decide whether a substitute will fit. Send the part number from the equipment, or the shaft and flange dimensions, and the team will identify the compatible alternative and the matching HS adapter sleeve and mounting accessories.

Frequently asked questions
- What does UKFS mean on an NSK flange unit?
- It denotes a square four-bolt flange housing fitted with a UK series insert bearing. The number after the letters gives the insert size, D1 marks sealing or design variants, and the accompanying HS code refers to the adapter sleeve.
- What information do I need to select a UKFS unit?
- Shaft diameter plus flange dimensions, meaning hole spacing and bolt size. Load type and the working environment also affect the choice. With those details the correct unit or replacement insert can be quoted.
- Can a UKFS unit replace a housing from another brand?
- If shaft diameter and flange dimensions line up, yes. Those dimensions define interchangeability. Send an unidentified part or another brand's number and the compatible equivalent can be confirmed.
