LINK-BELT PA housings in the 300 series are pillow block mounted bearing units built to carry rotating shafts on industrial machinery. They sit on a flat base, bolt down to the structure, and enclose the bearing while shielding it from contaminants. Typical installations include conveyors, mixers, pumps and fans. MR Industrial Accessories supplies this line and can help you match the right code to your shaft and load.

Reading the designation is straightforward: the letters PA come first, then a three-digit number. Within the 300 series there are multiple sizes, and those digits tell you the housing size together with the shaft diameter it fits. Smaller options in the range include PA319 and PA323, while PA339, PA343 and PA344 sit at the larger end. Because the full code pins down one specific part, having it on hand lets you order the exact housing or a suitable equivalent without guesswork.

In US plants and workshops, these units turn up on belt and chain conveyors, bucket elevators, mixers, agitators, centrifugal pumps and fans, as well as milling equipment, screens and food processing machinery. As pillow block designs, they make mounting onto steel frames or concrete pads simpler and let you line up the shaft within controlled tolerances. When a rugged support that is easy to service is needed in a plant running continuously, this type of unit is a frequent choice.

Choosing the right housing comes down to a few inputs: shaft diameter, the radial and axial loads involved, and the conditions where it will operate. Sealing deserves attention, since dusty, wet or frequently washed-down areas usually call for extra protection. Use the lubricant specified for the housed bearing, and mount on a base that is rigid and properly aligned so the assembly is not subjected to parasitic stresses. On equipment with vibration, check bolt tightness and internal clearance periodically. Careful installation pays off in the service life of the whole assembly.

LINK-BELT PA series housings have counterparts in other mounted bearing ranges, including lines from SKF, NSK, Timken and Dodge, though each maker applies its own nomenclature. Swapping one for another is not a direct fit: mounting dimensions, shaft diameter and load capacity all need to be compared first. MR Industrial Accessories can point you to the compatible alternative when you are replacing an existing unit. Send us the PA code stamped on the housing, or simply the shaft size, and we will quote the option that suits your equipment.

MR Industrial Accessories carries the LINK-BELT line. If the code you need does not appear, message us on WhatsApp with the model or size and we will quote it promptly. We can also advise on mounting, lubrication and related spare parts to keep your equipment running.
