This 4-bolt flange mounted unit pairs a cast iron housing with an NSK insert bearing, which can be spherical roller or ball depending on the series. It supports rotating shafts where front mounting and self-alignment are needed. MR Industrial Accessories LLC supplies this line to industrial plants across the United States and in several Latin American countries.
In the UKF code, the letters denote the 4-bolt flange housing and the following number gives the insert bearing size. Take UKF217D1;HA2317X and UKF218D1;HA2318X: the D1 suffix marks the insert bearing variant, while HA2317X and HA2318X are adapter sleeves for tapered shafts. Shaft sizes in this series run from 20 mm to 100 mm, with different sealing and fixing options to suit the application.
Typical installations include belt conveyors, bucket elevators, mixers, mills and process equipment in food, chemical, cement and mining operations. The flange simplifies mounting onto sheet metal or structural profiles, which is why these units also appear in industrial fans and large centrifugal pumps.
Selection depends on shaft diameter, radial and axial load, and site conditions. Match the seal to the level of dust, water or washdown. During mounting, the flange must sit flat and bolts should be tightened in a cross pattern; shaft alignment is handled through the insert bearing's internal radial clearance. Use high-quality lithium grease for lubrication and inspect the seal at every maintenance interval.
UKF units interchange with other brands that follow the 4-bolt flange standard, but housing dimensions and insert type can differ. When replacing, verify shaft diameter, hole spacing and insert fixing method. If a part number from another brand does not cross directly, MR Industrial Accessories LLC can identify a compatible alternative with the same mounting dimensions.

Frequently asked questions
- What does UKF indicate in a housing with bearing?
- UKF is a 4-bolt flange housing for an insert bearing. The number after it gives the insert size, the D1 suffix identifies the bearing variant, and the HA code in some models refers to the adapter sleeve for tapered shaft.
- How do I select the right seal?
- Consider the environment: a standard seal works for dry dust, while washdowns or humidity call for a higher-tightness seal. If chemicals are present, ask about special materials. MR will advise based on the contaminant and cleaning frequency.
- Can I replace another brand's unit with a UKF NSK?
- Yes, provided the shaft diameter, flange hole spacing and insert fixing type match. UKF units follow a common dimensional standard, but confirm these details before mounting. If unsure, send the original part number and we will identify the equivalent.
