This NSK mounted unit pairs a cast iron pillow block housing with an insert bearing that mounts on a tapered adapter sleeve. The design allows the bearing to grip the shaft without any seat machining, which keeps installation straightforward and helps absorb minor misalignment in service.

The UKP code identifies a two-bolt pillow block housing with insert bearing, and the number that follows tells you the shaft size. UKP217D1 and UKP317D1 both take an 85 mm shaft, while UKP218D1 and UKP318D1 take a 90 mm shaft. The D1 suffix marks a variant of the insert construction. When an adapter sleeve is specified, it appears as HA2317X or HA2318X, matching the housing to a shaft with commercial tolerance.

These units are common in food processing, textiles, cement and transport operations. You will find them on belt conveyors, mixers, fans, pumps and packaging lines. The gray cast iron housing handles moderate radial and axial loads, and the insert's double-lip seal helps keep dust and moisture out. Because the unit is self-aligning, small mounting errors are tolerated and assembly on metal structures is simpler.

Selection depends on shaft diameter, the radial and axial loads involved, and the working environment. The tapered adapter sleeve calls for a shaft within the correct tolerance and proper tightening of the lock nut. Inserts arrive pre-lubricated, but in harsh conditions it pays to inspect the seal and relubricate if a grease fitting is present. Line up the mounting holes with the structure to avoid unnecessary stress on the bearing.

NSK UKP units follow standardized dimensions and can be cross-referenced with other brands using the same nomenclature. If you have a part number from a different supplier, an equivalent with the same shaft size and hole pattern can be identified. Send the complete housing part number, such as UKP217D1;HA2317X, or the shaft dimensions and hole spacing, and the team will confirm the correct unit for your equipment.
