The NSK UK series is a ball insert bearing that mounts on an adapter sleeve. Its inner ring is extended and machined with a 1:12 taper, and the D1 suffix indicates both that taper and the sleeve slot. This arrangement suits split housings and shafts where fitting and removal need to be straightforward, and it lets maintenance staff set radial clearance through the sleeve rather than by pressing the bearing.

Reading the code helps you order the right combination. UK205D1 is a 25 mm tapered bore insert matched to an HE2305 adapter sleeve; UK305D1 shares that 25 mm bore but uses series 3 outer dimensions. The HE sleeve is ordered on its own and sets the shaft size, so HE2305 fits a 20 mm shaft. Confirm the full part number before ordering so the insert, sleeve and housing line up.

Typical duty includes belt conveyors, bucket elevators, mixers, mills and process lines in food, chemical and cement operations. The self-aligning action and sealing suit dusty areas and moderate humidity, and agricultural equipment such as seeders and combine harvesters often relies on this design when the shaft is long and the housing must be split.

When selecting, look at shaft diameter, whether the housing is split or solid, and the working environment. The standard seal is a double lip with a nitrile radial shaft seal for dust and splashes; frequent washdowns may call for a special seal. Fit the bearing on the adapter sleeve, tighten with the lock nut, align the housing and apply lithium grease beforehand. Tightening the sleeve sets radial clearance automatically.

Interchange is possible with other brands that use the same dimensional standard, including SKF, FAG and NTN, provided bore, outer dimensions and locking method agree. The HE sleeve is also a standard item sold separately. For a replacement, send the original part number or the shaft and housing dimensions and we will identify the matching reference.

To request a quote, message us on WhatsApp with the complete part number, for example UK205D1 together with its HE2305 sleeve, or with the shaft and housing dimensions. We will reply promptly and help you confirm the correct combination. If the series or suffix is unclear, a photo of the part is enough for us to assist with identification.
