A UKF flange unit pairs a cast iron housing with an NSK insert bearing, giving you a 4-bolt mounting point for rotating shafts in power transmission. Depending on the series, the insert is a ball or a spherical roller type. The design suits positions where shaft alignment and sealing have to be kept under control.
Reading the code is the first step. UKF tells you it is a flange housing with an insert bearing, and the figure after it is the shaft size taken from the series table, in millimeters or inches. A D1 suffix points to a sealing or internal design variant. So UKF206D1 and UKF207D1 take 30 mm and 35 mm shafts, while the 300 series runs from UKF306D1 with an HS2306 insert up to UKF310D1 with an HS2310 insert. Quoting the full code keeps the dimensions interchangeable.
Typical duty covers conveyors, mixers, pumps, fans and farm equipment, where four bolts let you fasten the unit to sheet metal or a frame. Processing plants handling food, cement and aggregates use them often, as do irrigation systems and seeders. The insert absorbs small misalignments and combined loads, which helps the shaft run longer and cuts downtime.
Selection comes down to three things: shaft diameter, whether the load is radial, axial or combined, and the surroundings. Dust, moisture or regular washdown call for heavier sealing. Bolt the unit to a flat, rigid surface, tighten the bolts in a cross pattern and never strike the insert. Grease from the factory is normally enough; on severe duty, inspect the seals and relubricate to suit the cycle.
NSK UKF units share the same flange and shaft diameter nomenclature as other brands, so they can be swapped dimensionally. On a replacement, compare hole spacing, flange diameter and whether the insert is ball or roller. Shaft size plus housing shape usually identifies the equivalent. MR Industrial Accessories can help you match one to your application.

Frequently asked questions
- What does UKF mean in a housing with insert bearing?
- It identifies a 4-bolt flange mounted unit with an insert bearing. U stands for unit, K for the insert type and F for the square flange. The number after it sets the shaft diameter from the series table.
- How do I choose between a UKF housing and another type of housing?
- Pick UKF when the unit bolts to a flat surface with four bolts and you want some self-aligning capability. A pillow block housing can be simpler for a horizontal shaft under mainly radial load. Space and environmental conditions also decide it.
- Are NSK UKF housings interchangeable with other brands?
- UKF units follow dimensional standards, so brands using the same nomenclature can be interchanged. Check hole spacing, flange diameter and insert type. If in doubt, send the code by WhatsApp or email and we will point out the equivalent.
