The UKP pillow block is a mounted pillow block bearing unit: it combines a cast iron housing with a tapered bore insert bearing, secured to the shaft by an adapter sleeve. It is used to support drive shafts in equipment requiring a robust, self-aligning and easy-to-mount unit. MR Accesorios Industriales sells this NSK line in Buenos Aires, Argentina, and quotes it via WhatsApp with the complete part number.

The UKP designation reads in blocks: UK indicates the tapered bore insert bearing with adapter sleeve, P the split pillow block housing with two mounting holes, and the number that follows gives the size of the assembly. In the series examples, combinations such as UKP211D1 and UKP311D1 appear, where the suffix D1 identifies the insert design variant. The adapter sleeve is designated separately, with the HE series, for example HE2311XY: the X corresponds to the shaft diameter in inches and the Y to the sleeve thread. To request a quote, send us the complete part number of the pillow block and the adapter sleeve.

These units are found in belt conveyors, bucket elevators, mixers, mills, packaging lines and process lines in food, chemical and aggregate plants. In Argentina they also appear in material handling equipment, blowers, centrifugal pumps and agricultural machinery. The pillow block housing allows mounting the shaft on a flat base and absorbing slight misalignments, which is useful when the frame is not perfectly rigid or when the shaft operates under deflection. It is a simple mounting solution for long shafts with multiple supports.

To select the unit properly, first define the shaft diameter and the corresponding HE adapter sleeve type. Check that the pillow block housing rests on a flat, machined surface, and that the two mounting bolts are properly tightened without deforming the base. The tapered insert is secured to the shaft by tightening the sleeve nut with the appropriate wrench, until the internal clearance is correct. The insert lubrication comes from the factory; in service, follow the machine's greasing schedule. If the equipment operates with dust or water, evaluate the insert sealing and the housing type.

Pillow block units are available from several brands and each manufacturer uses its own nomenclature for the insert, the housing and the adapter sleeve. Interchangeability is resolved by comparing shaft diameter, center height, distance between mounting holes and adapter sleeve type, not just the part number. When a customer brings an unidentified part or a part number from another brand, at MR Accesorios Industriales we cross-reference it and indicate the equivalent reference. If you need a variant you don't see, write to us via WhatsApp with the part number or model.

To finalize the quote, send us via WhatsApp the pillow block part number and the adapter sleeve part number, or directly the shaft size and the distance between the base mounting holes. With that data we quote the NSK unit that corresponds to your equipment and get back to you shortly. We can also advise you on mounting the tapered insert and adjusting the adapter sleeve so the unit runs aligned and with the expected service life.
