The NSK UELUP pillow block with insert bearing is a ready-to-mount unit that supports a rotating shaft on a horizontal surface. It combines a cast iron housing with an insert bearing that includes set screws and seals, so no additional machining of supports is required. This design suits equipment that needs simple alignment and permanent lubrication.

The code breaks down into functional parts. UEL identifies the insert bearing with set screws and sealing, while UP denotes the two-hole pillow block housing. The numbers that follow indicate the shaft diameter: for instance, UELUP204D1W3 fits a 20 mm shaft, and UELUP204-012D1W3 covers the same size in inches (3/4"). The D1 suffix refers to standard lubrication and sealing, and W3 indicates metric thread in the housing. Other examples include UELUP205-013D1W3 for 5/8" and UELUP205-100D1W3 for 1", both sharing the same body.

Typical applications include belt conveyors, packaging lines, mixers, fans, and transmission lines in food, chemical, and materials processing plants. In dusty or moderately humid environments, these units are common on milling equipment, screens, and bucket elevators. The pillow block mounting simplifies installation on stringers or flat bases, and the insert bearing can be replaced without dismantling the entire housing.

When selecting a unit, check the shaft diameter and the fixing method: set screw models are tightened with an Allen key, while taper bushing variants require a lock nut. Review the sealing as well—the UELUP series includes seals that guard against dust and splashes. During mounting, align the housing holes with the base and tighten the bolts evenly. Lubricate according to the service conditions and confirm the shaft turns freely before start-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, though seals and lubricant type may differ. To replace an existing unit, compare the shaft diameter, the distance between holes, and the center height. With those details, MR can quote the equivalent reference.

If you have the code of the unit you need, send it via WhatsApp or email and we will quote it promptly. We can also advise you if the pillow block operates under specific radial or axial loads. MR supplies the NSK UELUP series and other bearing housing lines to customers across the United States and in several Latin American countries.
