LINK-BELT PT3U pillow block housings are mounted units that combine a housing with an insert bearing. They are built to carry rotating shafts where the load is mostly radial and the mounting surface is flat with two bolt holes. Typical uses include transmission, conveying and process equipment, and the design allows alignment and protection of the bearing in dusty, damp or vibrating conditions. MR Industrial Accessories supplies this line.

Reading the PT3U code helps you select the right unit. PT tells you it is a pillow block housing with an insert bearing. The 3 sets the housing type, and U means the insert is a single-row bearing locked to the shaft with set screws. The number that follows gives the nominal shaft diameter in inches, following the series indicated by the code. A final N, when present, denotes a construction variant of the housing. With these details you can order either the complete unit or just the replacement insert.

These housings appear in belt conveyors, bucket elevators, mixers, mills, screens and process equipment in food, chemical and aggregate plants. They also serve fans, pumps and gear reducers that need simple support and straightforward mounting on steel or concrete structures.

Selection depends on shaft diameter, radial load and load direction. Inspect the seal lips for cuts or dirt that could let contaminants in. When mounting, set the housing on a flat, rigid surface, align the shaft with the equipment and tighten the insert set screws with the correct wrench. Apply the recommended grease and check axial and radial clearance before start-up.

Equivalent mounted units with a single-row insert and set screw locking can be interchanged between brands if the base dimensions, center height and shaft diameter match. To replace a LINK-BELT unit with another brand, compare those three values and the seal type. If you need an alternative, we can point you to the compatible size.
