Description
SKF PHE UJMB50 belongs to coupling, part of our Power transmission range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for PHE UJMB50 and any equivalents.
The SKF PHE UJMB is a jaw-style coupling that uses a polyurethane elastic insert to connect two shafts. It transfers torque while damping vibration and accommodating angular, radial, and axial misalignment. You will find it on pumps, fans, mixers, compressors, and conveyors in food processing, chemical, petrochemical, paper, and water treatment plants. MR Industrial Accessories supplies this coupling line as part of its power transmission range and can help you identify the right size or an equivalent.
Reading the code: PHE UJMB is the SKF family name for jaw couplings. The number that follows—such as PHE UJMB16 or PHE UJMB63—sets the size and correlates with the maximum shaft diameter and torque capacity. Larger numbers mean bigger hubs and higher torque. Suffixes within the series can point to different elastomer materials or hub styles. Always confirm the full part number when you request a quote.
Where they fit: these couplings handle misalignment that perfect shaft alignment cannot eliminate, so they suit centrifugal pumps, screw compressors, fans, mixers, agitators, screw conveyors, and belt conveyors. The polyurethane element resists oils, greases, and many solvents, but check chemical compatibility if aggressive substances are present.
Selecting a size: gather the equipment's nominal and maximum torque, the shaft diameters, the rotation speed, and the operating environment. Match those values to the coupling size that covers the application. No lubrication is required, which keeps maintenance simple. Periodically inspect the elastomer for wear and verify that the screws remain tight.
Replacing an existing coupling: jaw couplings from different brands can often interchange if the key dimensions match—outer diameter, overall length, shaft diameter, and the distance between hub centers. However, jaw profiles and elastomer compounds may vary slightly between manufacturers. Compare actual measurements rather than relying solely on the part number. MR Industrial Accessories can suggest a suitable equivalent.

Frequently asked questions
- What does PHE UJMB indicate on an SKF coupling?
- PHE UJMB is SKF's designation for jaw couplings. The following number indicates the size, which relates to the maximum shaft diameter and torque capacity. Each size covers a range of applications.
- Does this coupling require lubrication?
- No. The polyurethane elastic element runs dry. Maintenance consists of checking the elastomer condition and the screw tightness periodically.
- How do I select the correct PHE UJMB size?
- Consider the nominal and maximum torque of the equipment, the shaft diameters, and the rotation speed. With those data, choose the size that meets the requirements. Contact us by WhatsApp or email for help with selection.
