The NSK UKC series is a cartridge bearing unit that combines a cast iron housing with a tapered-bore insert bearing, mounted on a shaft using an adapter sleeve. It provides support where a rotating shaft needs alignment and sealing, commonly in transmission, conveying and process equipment. MR Industrial Accessories supplies this line and quotes by part number through WhatsApp or email, with help finding equivalents when needed.
The part number breaks down into clear segments. UKC indicates the cartridge unit with a tapered-bore insert; the digits that follow correspond to the housing and bearing size; and the D1 suffix identifies the sealing and lubrication variant. Available sizes in this series run from UKC205D1 through UKC212D1, including UKC205D1, UKC206D1, UKC207D1, UKC208D1 and so on. The adapter sleeve is ordered separately under the H series: H2305X, H2306X, H2307X, H2308X, H2309X, H2310X, H2311X and H2312X match each unit size. For a complete order, provide both the unit part number and the sleeve part number.
Typical applications include belt conveyors, elevators, packaging lines, mixers, blowers and process equipment where shafts are supported on walls or frames. The cartridge housing mounts directly to a wall or flange and centers the shaft without the need to machine a full housing, which simplifies maintenance on equipment with multiple support points. You will find these units in food processing, meat plants, mills, ceramics, aggregate operations, irrigation systems and agricultural machinery.
Selection starts with the shaft diameter and the corresponding H sleeve. Because the insert is tapered, it is secured with the sleeve and a lock nut, and the axial fit determines internal clearance. Check the sealing version against the environment: dust, water or frequent washdowns call for the appropriate protection. During assembly, align the housing with the shaft and the rest of the line, lubricate according to the insert type, and tighten the nut without forcing it. Misalignment or over-tightening reduces bearing life.
UKC units are interchangeable across brands by part number and size. The series designation and size number are the starting point, and the H sleeve is ordered separately. When replacing a unit from another brand, compare shaft diameter, fixing type and sealing before confirming an equivalent. If you have the old part or the equipment part number, send that information and we will identify the compatible unit.
MR Industrial Accessories supplies the NSK line and quotes the UKC unit with its H sleeve via WhatsApp or email. Send the complete part number, the shaft size or a photo of the part, and we will respond promptly with a quote. We also carry housings, bearings and mounting accessories to complete the replacement in a single inquiry.

Frequently asked questions
- What does UKC mean in a bearing unit with insert?
- UKC identifies the cartridge unit with a tapered-bore insert bearing. The number that follows indicates the size, and the D1 suffix corresponds to the sealing and lubrication version. The adapter sleeve is ordered separately under the H series.
- How do I choose the H sleeve for a UKC unit?
- Choose the sleeve by shaft diameter and unit size: each UKC matches an H sleeve of the same size, such as H2305X for UKC205D1 or H2312X for UKC212D1. Send the unit part number and shaft size and we will quote the assembly.
- Can a UKC unit from another brand be replaced?
- Yes. Interchangeability is defined by the series, size and fixing type. Compare shaft diameter, sealing and sleeve before confirming an equivalent. If you send the original part number, we will indicate the compatible unit and quote it.
