LINK-BELT PU Series 300 pillow blocks are mounted units that pair an insert bearing with a cast iron housing to support rotating shafts on a flat base. They are used when the shaft runs parallel to the mounting surface and you need rigid support with self-alignment. MR Industrial Accessories LLC supplies this line for transmission and conveying equipment in plants across the United States and several Latin American countries.

The PU prefix identifies a Series 300 pillow block. The number that follows—PU314, PU315, PU316, PU318, PU319, PU320, PU322 or PU323, for example—tells you the size and load capacity of the insert. A higher number means a larger shaft diameter and a more robust housing.

You will find these units on belt conveyors, bucket elevators, mixers, mills, screens and packaging lines. The cast iron housing handles dust, moisture and moderate radial loads. The insert's sealing keeps lubricant in and contaminants out, which helps extend service life in demanding environments.

To select a pillow block, start with the shaft diameter and the radial load it will carry. Check that the base is flat and rigid and that the holes line up with the mounting frame. During installation, align the shaft with the pillow block and tighten the fastening bolts evenly. The insert usually arrives pre-lubricated; in service, inspect the sealing and relubricate according to the duty cycle. The bearing's internal clearance compensates for slight misalignment, but it does not replace proper leveling.

Series 300 pillow blocks interchange between brands by shaft number and base configuration. You can replace one with another of the same diameter and capacity as long as the hole spacing and center height match. MR Industrial Accessories LLC can point you to a compatible alternative within the LINK-BELT line or other brands we supply.
