The NSK UELUP series pillow block with insert bearing is a mounted unit ready to be fixed to a horizontal surface. It integrates an insert bearing with set screws and a cast iron housing that allows mounting the shaft without machining additional supports. It is used in equipment where a rotating shaft needs to be supported with simple alignment and permanent lubrication. MR Accesorios Industriales sells this line for industrial applications in Buenos Aires, Argentina.

The UELUP designation reads in parts: UEL indicates the insert bearing with set screws and sealing, UP corresponds to the two-hole pillow block housing. The following numbers define the shaft diameter: for example, UELUP204D1W3 is for a 20 mm shaft, while UELUP204-012D1W3 identifies the same size in inches (3/4"). The suffix D1 refers to standard lubrication and sealing, and W3 to metric thread in the housing. The examples UELUP205-013D1W3 and UELUP205-100D1W3 show 5/8" and 1" variants for the same body.

These pillow blocks are used in belt conveyors, packaging belts, mixers, fans and transmission lines in food, chemical and materials plants. In Argentina they are common in milling equipment, screens and bucket elevators, where the environment may be dusty or moderately humid. Their pillow block mounting facilitates installation on stringers or flat bases, and the insert bearing allows replacement without disassembling the complete housing.

To select the pillow block, verify the shaft diameter and the type of fixing: models with set screws are tightened with an Allen key onto the shaft, while variants with taper bushing require a lock nut. Check the sealing: the UELUP series includes seals that protect against dust and splashes. During mounting, align the housing holes with the base and tighten the fixing bolts evenly. Lubricate according to the service conditions and verify that the shaft turns without effort before starting up.

NSK UELUP units can be interchanged with other brands that follow the same standard for pillow block housings and insert bearings with set screws. Metric and inch sizes maintain dimensional compatibility between manufacturers, although seals and lubricant type may vary. If you need to replace an existing unit, compare the shaft diameter, the distance between holes and the center height. With that data, MR Accesorios Industriales will quote the equivalent reference.

We can also advise you if the pillow block is mounted on equipment with specific radial or axial load.
