Link-Belt PT3U2E pillow blocks are two-bolt mounted bearing units that fasten to a flat base and carry a rotating shaft. They suit power transmission and conveying duty where the support has to stay rigid and alignment has to be straightforward. MR Industrial Accessories LLC supplies this line, and the part number sets the shaft size.
The code breaks down into segments. PT stands for the pillow block type. The 3 covers the housing design. U means the unit comes with an inserted bearing. The 2 places it in the 200 dimensional series. E identifies the sealing type, and N identifies how the inner ring locks. In PT3U2E20N and PT3U2E32N, the digits 20 and 32 give nominal shaft diameters in millimeters, so the same housing family covers a range of shaft sizes.
Typical duty includes belt and roller conveyors, mixers, mills, bucket elevators and packaging lines. Plants running this type of equipment deal with dust, humidity or frequent washdowns, and the 200 series sits in the medium-duty part of the mounted bearing range, which fits moderate loads and the speeds normally found in standard power transmission drives.
Selecting the right unit comes down to three things: shaft diameter, whether the load is radial, axial or combined, and the environment around the bearing. The E seal handles dust and splashes. Where high-pressure washdown is routine, look at extra protection. Mounting calls for a flat, rigid base with the holes lined up and bolts tightened evenly. Regrease on the duty cycle, and set internal clearance when the inner ring is locked with the N system.
For a replacement, do not match on part number alone. Check the base dimensions, the height to the shaft center and the shaft diameter. A series from another manufacturer can differ in sealing or locking even when the numeric designation looks the same. Send the full part number and the main dimensions, and the team can point you to a compatible option.
