The UKFL housing with NSK insert bearing is a four-bolt flanged mounted unit that pairs a cast iron housing with a UK series insert bearing. It secures to the shaft using an adapter sleeve, which facilitates adjustment and allows it to carry moderate radial and axial loads. Typical use is in transmission, conveying and process equipment that needs firm support and straightforward mounting.

The UKFL code identifies a flanged unit with a UK series insert bearing. UK denotes the bearing with taper sleeve, FL the four-bolt square flange, and the number that follows—209, 210, 211, 213, 215, 216, 309, 310—gives the shaft diameter the unit fits. The D1 suffix refers to the insert design, and the HA code that accompanies it identifies the adapter sleeve used to complete the shaft mounting.

These units appear in belt conveyors, elevators, mixers, fans, pumps and agricultural or food machinery. The four-bolt flange simplifies anchoring to steel structures or masonry, while the adapter sleeve allows mounting on shafts without machined shoulders—useful in existing equipment or repairs where the shaft is already in service.

When selecting the unit, consider shaft diameter, load type and environmental conditions. The insert seal determines protection against dust and moisture; choose the appropriate design for outdoor duty or frequent washdowns. Tighten the HA sleeve with a precision nut, and check flange alignment and axial clearance before start-up. Lubricate the insert through the built-in grease fitting at the interval the manufacturer indicates for the speed and operating temperature.

UKFL units from different brands share standardized flange dimensions and shaft diameters, so they are often interchangeable. When replacing an existing unit, compare hole spacing, flange diameter and sleeve type. To identify a part without a code, the main dimensions and a photo are sufficient. MR Industrial Accessories LLC quotes the exact code or size you need and can suggest equivalents or help choose a variant for your equipment.
