Description
NTN UELT317-307D1W3 belongs to take-up 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 UELT317-307D1W3 and any equivalents.
A take-up bearing unit from NTN in the UELT2 and UELT3 series pairs an insert bearing with a cast iron housing. It carries transmission shafts and takes up misalignment on industrial equipment. Maintenance teams use these units where belt or chain tension has to be adjusted as part of normal operation.
Reading the code helps when you order a replacement. UEL points to the insert bearing with set screws, T to the take-up housing, and the digit after it (2 or 3) sets the section. The suffixes D1 and W3 cover sealing and locking options, with D1 generally the higher-protection seal and W3 a screw locking type. So UELT204-012D1W3 is an insert for a 3/4" shaft in a take-up housing, while UELT205D1W3 fits a 25 mm metric shaft.
You will find these units on conveyors, bucket elevators, mills, mixers and process lines in food, chemical and cement plants, plus agricultural machinery and material handling equipment. The take-up design lets you adjust belt or chain tension, which suits flexible transmission systems.
Selection comes down to three things: shaft diameter, locking method (set screws or taper) and the sealing the environment calls for. During installation, line the housing up with the shaft and tighten the locking screws to the recommended torque. Keep the housing perpendicular to the shaft so axial loads do not build up, and stay on top of lubrication and D1 or W3 sealing where dust or moisture is present.
NTN Y-bearings with insert bearing interchange with other brands built to the bearing unit standard. Give us another brand's part number and we can match it to the NTN equivalent. The UELT2 and UELT3 series spans a broad range of metric and inch shaft sizes. Confirm the critical housing dimensions before you replace a unit.
For a quote, send the complete part number, or the shaft dimensions together with the housing type, over WhatsApp or email. We help you settle on the right variant and can suggest equivalents when the original reference is unclear.

Frequently asked questions
- How do I work out the correct part number for a UELT housing?
- The number carries the shaft size (204 for 20 mm or 3/4", for instance), the housing type (T for take-up) and the D1 and W3 suffixes for sealing and locking. Send the full part number or the dimensions and we will quote the exact reference.
- How does a UELT housing differ from a UCP?
- UELT is a take-up housing with insert bearing, built so belt or chain tension can be adjusted. UCP is a fixed pillow block housing. The inserts are similar, but the two mount and function differently. Tell us about your application and we will point you the right way.
- Can NTN housings be swapped with other brands?
- Insert bearing units follow dimensional standards, so interchange between brands is possible. If you have another brand's part number, we can identify the NTN equivalent and quote the right option.
