For maintenance teams working with housed bearing units, the NTN UCX insert is a ball bearing that features an extended inner ring. It fits into split plummer block housings, take-up frames and pillow blocks, and set screws hold it on the shaft. This design lets you align and remove the bearing without tearing down the machine, which makes it a practical choice for transmission equipment that runs on nominal shaft diameters and needs a replaceable insert with decent protection against dust and moisture.

Reading a UCX part number is straightforward once you know the pattern. The letters UCX mark the insert family with extended inner ring and set screw locking. The digits that follow tell you the shaft size, either in inches or the metric equivalent. Take A-UCXO5-013D1M or A-UCXO7-105D1M: the middle number block gives the shaft dimension, while the suffix at the end covers sealing, tolerance and locking variations. If you are unsure, send us the shaft diameter and the housing type and we will match the right number.

You will find these inserts in conveyors, belts, elevators, mixers, mills, pumps and fans. They suit shafts turning at moderate speeds and carrying combined radial and axial loads. The UCX line covers many sizes and is frequently requested for replacement in equipment that operates many hours per day.

Selection comes down to a few key details: shaft diameter and tolerance, housing style (pillow block, flange or take-up), load, and operating speed. Sealing matters a lot. In dusty or wet areas, choose reinforced protection. During mounting, clean the seat, verify alignment and tighten the set screws onto the shaft with the correct wrench. Follow the duty cycle for lubrication and check axial clearance before start-up.

UCX inserts interchange between brands that share the same nomenclature and standardized dimensions. A compatible insert from another maker can work as long as the shaft diameter, inner ring width, locking method and sealing match. Send us the old part number or the shaft and housing dimensions, and we will point you to the compatible option.
