LINK-BELT PT3U pillow block housings are mounted units with an insert bearing, designed to support rotating shafts in applications where the load is mainly radial and a fixed base with two mounting holes is required. They are used in transmission, conveying and process equipment, and allow the bearing to be aligned and protected in environments with dust, moisture or vibration. MR Accesorios Industriales sells this line.

The PT3U designation is read in parts: PT indicates a pillow block housing with insert bearing, 3 defines the housing type and U indicates that the insert is a single-row bearing with set screws for shaft locking. The final number corresponds to the nominal shaft diameter in inches according to the series indicated by the code. The final letter N identifies a construction variant of the housing. With this data, either the complete unit or the replacement insert can be selected.

These housings are used in belt conveyors, bucket elevators, mixers, mills, screens and process equipment in food, chemical and aggregate plants. In Argentina they are common in the oilseed, meatpacking and cement industries, where the environment demands a robust housing and sealing that retains lubrication. They are also used in fans, pumps and gear reducers that need simple support that is easy to mount on steel or concrete structures.

To choose correctly, check the shaft diameter, the radial load and the load direction. Check the condition of the seal: the lips must be clean and free of cuts to prevent contaminants from entering. During mounting, rest the housing on a flat, rigid surface, align the shaft with the equipment and tighten the insert set screws with the corresponding wrench. Lubricate according to the recommended grease type and check axial and radial clearance before start-up.

As for equivalents, pillow block mounted units with a single-row insert and set screw locking are interchangeable between different brands as long as the base dimensions, the center height and the shaft diameter match. To replace a LINK-BELT with another brand, compare those three values and the seal type. If you need an alternative, at MR Accesorios Industriales we will indicate the option compatible with your size.

If you cannot find the exact variant, write to us with the shaft diameter and the working conditions: we will quote the unit or the insert that best suits your application.
