LINK-BELT PLY N series pillow blocks are mounted units that combine an insert bearing with a cast iron housing designed to be bolted to a flat base. They are used to support rotating shafts in conveyors, fans, mixers and other equipment where rigid support and simple alignment are required. MR Accesorios Industriales supplies this line as an official brand, with alternatives for every application.
The PLY designation identifies the family of pillow blocks with insert bearing. The number that follows —319, 323, 327, 331, 335, 339, 343 or 347— indicates the housing size and the shaft diameter each unit accepts. The final letter N distinguishes the construction variant within the series. With those three data points you can locate the exact reference you need and check the size that matches your shaft.
These pillow blocks are chosen in food and beverage plants, water treatment plants, cement plants, sugar mills and agro-industrial facilities. They also appear in belt conveyors, bucket elevators, exhaust fans and agitators. In the Argentine market they are found in production lines that require robust support and easy replacement, with the advantage that the insert bearing can be replaced without disassembling the entire assembly.
To select the correct pillow block, consider the shaft diameter, the radial and axial load it will support, and the type of sealing required by the environment. In dusty or humid areas, a tighter seal is advisable; in high-temperature applications, check the lubrication and internal clearance. Mounting must be done on a machined and aligned base to avoid stress on the bearing and extend its service life.
LINK-BELT PLY N series pillow blocks are interchangeable with other brands offering equivalent dimensions, provided the shaft diameter, bolt hole spacing and center height match. When requesting a quote, it is best to indicate the complete reference or the main dimensions so we can offer you the compatible alternative. MR Accesorios Industriales advises you so the replacement is direct and without modifications to the equipment.

With more than 80 years in the industry, at MR Accesorios Industriales we know the needs of Argentine industry and support you in the selection.

- Are they compatible with pillow blocks from other brands?
- Yes, in general they are interchangeable with other brands that use the same shaft dimensions, bolt hole spacing and center height. When requesting a quote, indicate the reference or the main dimensions so we can offer you the alternative that best fits.
