LINK-BELT Z series pillow blocks are mounted units that combine an insert bearing with a pillow block housing, ready to be fixed to the structure and support rotating shafts. They are used when the shaft must rest on a flat base, with simple alignment and built-in lubrication. MR Accesorios Industriales sells this line as an official brand and advises you to choose the right unit according to shaft diameter and load type.

The Z series designation is read with the shaft number first and the letter Z at the end: for example, 21214Z corresponds to a pillow block for a 2 1/4 inch shaft, and 21215Z for 2 3/16 inches. The Z suffix identifies the construction variant within the pillow block family. In the series codes, the initial digits indicate the unit type and nominal shaft diameter; the final number, the housing configuration. To correctly interpret each reference, send us the complete code and we will tell you the equivalent.

These pillow blocks are used in belt conveyors, bucket elevators, mixers, mills, centrifugal pumps and process equipment in food, chemical and aggregate plants. In Argentina they are common in the oilseed industry, in milling plants and in packaging lines, where a robust and easy-to-maintain support is needed. They are also used in industrial fans and in low and medium speed transmission shafts. Their pillow block housing allows mounting on metal structures or concrete bases with four bolts.

To select the pillow block, take into account the shaft diameter, the radial and axial load it must withstand, and the environmental conditions. Verify that the base is flat and rigid to avoid deformations that affect internal clearance. Lubrication must be as indicated by the manufacturer and renewed according to the duty cycle. If the equipment operates with dust or humidity, choose the variant with adequate sealing. Alignment between pillow blocks is key: angular or parallel misalignment accelerates wear of the bearing and housing.

LINK-BELT Z series pillow blocks are interchangeable with other brands of mounted pillow blocks that follow the same basic dimensions and the same shaft diameter.
