For rotating shaft support where a stable front mount is needed, the NSK UKF flange housing with insert bearing offers a 4-bolt, cast iron solution. It pairs an insert bearing with a flanged housing, keeping installation simple and alignment straightforward. This makes it a practical choice for low to medium speed drives that require few components to secure the shaft. MR Industrial Accessories supplies this line for a range of industrial applications.
The UKF code denotes a series of 4-bolt flange housings. In part numbers such as UKF208D1, UKF209D1 and UKF213D1, the first two digits signal the insert bearing series—series 2 for light shafts, series 3 for heavier shafts—while the final digit gives the shaft diameter per the coding system. The D1 suffix identifies a specific insert construction variant. For complete assemblies with the insert already installed, the HS code is used, as in HS2308X, HS2309X or HS2313X.
Typical applications include conveyors, belts, elevators, mixers, fans and agricultural machinery. They also appear in food processing, cement production, aggregate handling and maintenance shops. The 4-bolt flange mounts directly to sheet metal or steel structures with bolts, which simplifies replacement and shortens downtime. Pumping equipment and packaging lines that need stable front mounting also rely on these units.
Selection depends on shaft diameter, load type (radial, axial or combined) and operating environment. In dusty, wet or vapor-heavy settings, choose an insert with appropriate sealing. Make sure the flange seats correctly and tighten bolts evenly to prevent distortion. Lubrication typically comes pre-applied from the factory; during service, replenish it according to the duty cycle. Proper alignment between housings is critical to avoid straining the bearing.
UKF housings are interchangeable across brands that follow the same dimensional nomenclature. If a customer provides a code from another manufacturer, the equivalent can be identified by shaft dimensions and flange type. Series 2 and 3 generally cover the most common diameters, while suffixes denote sealing or locking variations per the code. To confirm interchangeability, compare shaft diameter, hole spacing and center height. MR Industrial Accessories can help you find the exact code.

- How do I choose the right UKF housing for my shaft?
- Measure the shaft diameter and the distance between flange holes. Consider load type and environmental conditions to select the sealing. If unsure, send us the code or size on WhatsApp and we will quote the exact reference.
- Are NSK UKF housings interchangeable with other brands?
- In general, UKF units follow dimensional standards that allow interchangeability between brands. To confirm, compare shaft diameter, hole spacing and center height. If you have another brand's code, we will indicate the compatible equivalent.
