The NSK UKPX line pairs a cast pillow block housing with a spherical insert bearing, giving you a ready way to support a rotating shaft on a fixed frame while absorbing small amounts of misalignment. It suits industrial power transmission work where space is tight and the mounting surface is not perfect.
Reading the code tells you most of what you need. UKPX names the housing series; in UKPX08D1, UKPX09D1 and UKPX13D1 the digits after UKPX give the shaft size in inches, and D1 marks an insert variant. The HS numbers shown alongside them (HS2308X, HS2309X, HS2313X) are the adapter sleeves, where the first pair of digits sets the sleeve type and the second pair the shaft size.
You will see these units on conveyors, belts, elevators, mixers, mills and other process lines, as well as in road machinery and material handling equipment. Their split-style mounting makes them straightforward to bolt onto steel or concrete, and the spherical insert keeps them working when the shaft is not perfectly true.
Selection comes down to shaft diameter, the radial and axial loads involved, and where the unit has to live. The insert seal is what keeps dust and moisture out, so match the seal to the conditions. Align the housing with the shaft, tighten the mounting bolts, lubricate on schedule and set the internal clearance correctly; the spherical insert then handles minor angular error on its own.
NSK UKPX units can be swapped for other brands built to the same Y-bearing housing standard, but the fit is not automatic. Compare shaft diameter, hole spacing, height to center and locking method before committing, and check tolerances as well. If you send us the part number or the size you need, we will confirm the reference and point you to a compatible alternative where one exists.

Frequently asked questions
- How do I read an NSK UKPX part number?
- UKPX is the pillow block housing series. The number that follows is the shaft diameter in inches, and a D1 suffix denotes an insert variant. The matching HS adapter sleeves carry the sleeve type in their first two digits and the shaft size in the next two.
- What should I check before choosing a unit?
- Work from the shaft diameter, the radial and axial loads, and the operating environment. Confirm the seal type and the locking method. If anything is unclear, send your equipment details and we will help you narrow it down.
- Can an NSK UKPX unit replace a housing from another brand?
- Often yes, provided the main dimensions and insert type line up. Check shaft diameter, hole spacing, height to center and locking style. We can help you identify the equivalent that fits your machine.
