When a shaft needs support and the housing splits open for mounting without tearing down the assembly, an insert bearing in the UCS series is a common choice. MR Industrial Accessories LLC supplies this line for transmission and conveying equipment from its Miami base, serving customers across the United States and in several Latin American countries.
Reading the UCS code helps you order the right replacement. The letters UCS point to an insert with a spherical outer ring and set screw locking. The number after the letters gives the shaft diameter, in inches or millimeters depending on the variant. A suffix such as D1 tells you the seal type and internal tolerances. For instance, UCS213-208D1 is an insert for a 1.1/4" shaft with D1 sealing, while UCS213D1 is the metric version for 65 mm.
These inserts show up in belt conveyors, bucket elevators, mixers, mills and process equipment in food, chemical and aggregate plants. They handle humid or dusty conditions well. Because the split plummer block housing opens, you can swap the insert without pulling the shaft, which cuts downtime.
To select a UCS insert, confirm the shaft diameter, the locking method (set screws or eccentric) and the sealing you need. D1 generally means nitrile seals with an extra lip that holds grease in and keeps contaminants out. During mounting, clean the housing seat, align the shaft and tighten the set screws with a torque wrench. Use general-purpose lithium grease and check axial clearance before startup. Poor alignment speeds up seal wear.
NSK UCS inserts interchange with other brands that follow the same split plummer block housing standard, provided the shaft diameter, inner ring width and locking hole positions match. For a quote, send the complete code of the original part or the shaft and housing measurements. MR can suggest a suitable equivalent without compromising how the equipment runs.

Frequently asked questions
- What does the D1 suffix mean on a UCS insert bearing?
- D1 identifies the seal type, typically nitrile lips that retain grease and block dust or water. Keep the same suffix when replacing the part to maintain the original protection.
- How do I choose the right UCS insert bearing for my shaft?
- You need the shaft diameter, locking type and sealing. Provide the complete code of the old part or the shaft and split plummer block housing measurements. With that, MR can quote the exact reference and advise on mounting.
- Are NSK UCS inserts compatible with other brands?
- They interchange with inserts from other brands that comply with the same split plummer block housing standard, as long as the shaft diameter, width and hole locations match. If you have a code from another brand, MR can tell you the compatible equivalent.
