The NSK UKFS unit is a four-bolt flange housing supplied with a UK-series insert bearing that mounts on the shaft through an adapter sleeve. It bolts to a flat face so the shaft sits at a right angle to that surface, which keeps anchoring and service work straightforward. You will see it on low and medium speed drives where the shaft needs firm support.

Reading the code helps when you order. UK points to the insert bearing used with an adapter sleeve, F to the flange housing, and S to the four-bolt pattern. The digits that follow give the bearing and housing size. D1 marks the insert design, and the HA code after the semicolon identifies the adapter sleeve.

Typical duties include conveyors, belt systems, elevators, mixers, fans and process lines that run continuously. Dusty or damp plants in food processing, cement, chemicals and agriculture are common places to find them. Pumping equipment and packaging lines also use this mounting style.

Selection starts with shaft diameter, radial and axial load, and the conditions on site. The insert seal keeps dust and moisture out; in harsh environments, extra protection is worth considering. The adapter sleeve lets you fix the bearing on a shaft without a shoulder and set internal clearance. Check housing alignment and shaft perpendicularity during installation, keep lubrication up to date and re-tighten periodically. The four-bolt flange spreads the load across the mounting face.

NSK UKFS units can replace other brands' four-bolt flange housings with insert bearing and sleeve when the main dimensions and fixing method line up. Compare shaft diameter, hole spacing and center height before swapping. If a code from another brand does not match, the team can point you to the compatible option.
