Link-Belt PU3K series pillow blocks are mounted bearing units designed to secure rotating shafts to a flat base. They are used in power transmission equipment where rigid support and stable alignment are required. Their robust construction makes them suitable for demanding industrial applications with moderate radial and axial loads. MR Accesorios Industriales supplies this line as an official brand, with more than 80 years of experience in the field.
The PU3K designation identifies a pillow block of the 300 series. The number following the letters indicates the size: for example, PU3K27, PU3K31 and PU3K35 correspond to different shaft capacities. The PU prefix indicates the housing type, the K refers to the mounting configuration and the initial 3 places it in the series. These codes allow you to select the right unit according to shaft diameter and load conditions.
In Argentine industry, these pillow blocks are used in conveyors, mills, mixers, pumps and fans. They also appear in mining, cement, food and water treatment equipment. Their pillow block design facilitates mounting on steel structures or concrete bases, and allows for some initial misalignment. They are common in plants where simple maintenance and quick replacement are required.
To choose correctly, take into account the shaft diameter, radial and axial load, and environmental conditions. Check the sealing: pillow blocks may incorporate seals that protect against dust and moisture. Lubrication must be adequate and mounting must ensure precise alignment to avoid parasitic stresses. Follow the manufacturer's recommendations for tightening and fastening.
Link-Belt PU3K series pillow blocks are interchangeable with other brands offering mounted bearing units of equivalent dimensions.
