Description
NTN UCPX-3M belongs to pillow block bearing, part of our Bearing housings range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for UCPX-3M and any equivalents.
A UCPX pillow block from NTN pairs a cast iron housing with an insert bearing that locks to the shaft by set screws. It gives conveyors, agitators, fans and similar machines a self-aligning support that tolerates slight misalignment. We supply this line and help you match the right unit to your shaft and application.
Reading the code: UCPX is a pillow block unit with an insert bearing. The X marks the higher-capacity series within the mounted units range. Numeric suffixes such as UCPX-1M, UCPX-2M and UCPX-3M cover different shaft sizes and capacities, while the trailing M points to sealing or locking variants that differ by manufacturer. For exact dimensions and capacities per size, check the tables in the NTN Bearing Units A-21000 catalog.
These units appear in belt conveyors, bucket elevators, mixers, mills, centrifugal pumps, food and beverage processing equipment, industrial fans, textile machines and bottling lines. The pillow block shape mounts on a flat surface, and the insert bearing's self-aligning action absorbs small misalignments. We supply plants and workshops across the United States and in several Latin American countries.
Selection starts with shaft diameter, radial and axial loads, and the operating environment. The insert bearing's seal keeps out dust and moisture; where humidity is high or washdowns are frequent, extra protection is worth considering. Use the lubricant the manufacturer specifies and renew it according to the duty cycle. At mounting, verify alignment between pillow block and shaft, then tighten the set screws so the inner ring cannot slip. Getting installation right is what keeps the unit running.
On interchangeability: NTN UCPX pillow blocks can be replaced by units from other makers that use the same international nomenclature. Even so, shaft diameter, mounting hole spacing and center height may differ from one maker to another. Before substituting an existing pillow block, compare the actual measurements or ask our technical team. We help you find the unit that fits your equipment.
To get a quote, send the code or your shaft measurements by WhatsApp or email. If you have a code from another brand or an unidentified part, we reply promptly and point you to a compatible equivalent. We can also help you choose the right configuration.

Frequently asked questions
- What does UCPX mean on a pillow block?
- UCPX identifies a pillow block with insert bearing in the UCPX series. U stands for mounted unit, C for pillow block, P for insert bearing, and X for a higher-capacity series. The numbers and letters that follow, as in UCPX-1M, set the size and sealing variant.
- How do I pick the right UCPX pillow block for my shaft?
- Start with the shaft diameter and the radial and axial loads. Then look at the environment: dust, moisture or washdowns call for reinforced sealing. With those details, we can quote the exact code.
- Can NTN UCPX pillow blocks be swapped with other brands?
- They can be interchangeable when the nomenclature and critical dimensions match, such as shaft diameter and hole spacing. Small differences between makers are possible. If you bring a code from another brand or an unidentified part, we point you to the compatible equivalent.
