NTN UC215 insert bearing dimensions
The NTN UC215 is a self-aligning insert bearing with a 75 mm bore, 130 mm outer diameter and 34 mm width, supplied new for maintenance and repair tasks. It fits standard UC-series housings and supports rotating shafts in conveyors, agricultural equipment and general industrial machinery.
UC-series housing compatibility limits
The bearing matches the UC215 envelope, so it only fits housings machined to the same 130 mm outside diameter and 34 mm width; wider or narrower pillow blocks will not accept it. Load ratings and speed limits follow the UC215 catalogue values, so applications exceeding those figures require a different bearing series.
Installation notes and common issues
Press the bearing onto the shaft using a sleeve that contacts the inner ring only; hammer blows on the outer ring or housing will brinell the raceways. Tighten the set screws to the manufacturer’s torque value and re-check after the first run-in period, as loose screws are the most frequent cause of premature failure. Builders needing a different bore size or a sealed-for-life unit cannot use this insert.

Questions about this item
Which NTN UC215 insert bearing size should I choose for a 75 mm shaft?
The NTN UC215 is built for a 75 mm shaft, with a 130 mm outer diameter and 34 mm width, so it fits that exact shaft size.
What does the 34 mm width mean once the bearing is installed in a machine?
The 34 mm width determines the axial space the bearing occupies on the shaft and the load-carrying surface inside the housing.
What mounting standard does the UC215 follow and what does it cap in practice?
The UC215 uses a set-screw locking collar on a cylindrical bore, limiting shaft tolerance to a standard clearance fit for electric motor and conveyor applications.
