LINK-BELT PA housings, series 300, are pillow block mounted bearing units used to support rotating shafts in industrial equipment. They are mounted on a flat base and fastened with bolts, and their design allows housing the bearing and sealing it against contamination. They are used in conveyors, mixers, pumps and fans, among other applications. At MR Accesorios Industriales we sell them and advise you on choosing the correct code according to your shaft and load.

The designation of these housings is read as PA followed by three digits. The 300 series covers several sizes, and the numbers indicate the housing size and the shaft diameter that each unit accepts. For example, PA319 and PA323 correspond to smaller sizes in the series, while PA339, PA343 and PA344 cover larger sizes. The complete code identifies the part unambiguously: with that data you can order the exact housing or its equivalent.

In Argentine industry, these housings appear in belt and chain conveyors, bucket elevators, mixers, agitators, centrifugal pumps and fans. They are also found in milling equipment, screens and machines for the food industry. Being pillow block units, they simplify mounting on metal structures or concrete bases, and allow aligning the shaft with controlled tolerances. They are a common solution when a robust and easy-to-maintain support is needed in continuous production plants.

To select the correct housing, take into account the shaft diameter, the radial and axial load it must support, and the environmental conditions. Sealing is key: in environments with dust, water or frequent washdowns, additional protection is advisable. Lubrication must be the one indicated for the housed bearing, and mounting requires a rigid and aligned base to avoid parasitic stresses. If the equipment works with vibrations, check the bolt tightness and internal clearance. Careful mounting extends the service life of the assembly.

LINK-BELT PA series housings have equivalents with other mounted bearing lines from manufacturers such as SKF, NSK, Timken or Dodge, although each brand uses its own nomenclature. Interchangeability is not automatic: mounting dimensions, shaft diameter and load capacity must be compared. At MR Accesorios Industriales we indicate the compatible alternative if you need to replace an existing unit. Send us the PA code on the housing or the shaft size and we will quote the option that best suits your equipment.
