The NSK UELFLU series 4-bolt flange Y-bearing unit is a ready-to-mount assembly that pairs a cast iron flange housing with an insert bearing. The housing has four mounting holes for fastening to flat surfaces, and the insert bearing is secured to the shaft with set screws. This design supports rotating shafts where a firm, rigid mounting and straightforward alignment are needed.

The UELFLU part number breaks down into meaningful segments: UEL identifies the insert bearing with set screws and a wider inner width, FL denotes the 4-bolt flange housing, and U specifies the mounting configuration. The digits that follow indicate the shaft diameter. Suffixes provide additional detail: D1 indicates a polyamide cage, and W3 indicates metric set screw thread.

These units are commonly found in belt conveyors, packaging lines, flour mills, feed plants, and irrigation equipment. They are also used in meatpacking operations, maneuvering yards, and agricultural machinery, where mounting on sheet metal or structural profiles demands a rigid flange and a bearing that accommodates slight misalignment. The UELFLU series covers shaft diameters from 20 mm to 50 mm, with inch variants available for direct replacement.

When selecting a unit, consider the shaft diameter, load type, and environmental conditions. The insert bearing's seal protects against dust and moisture; in frequent washdown areas, verify the seal type is suitable. Internal clearance and lubrication are set at the factory, but proper mounting requires the flange to rest on a flat surface and the four bolts to be tightened evenly. Tighten the set screws onto the shaft with the correct wrench, without hammering.

Cross-references between brands are common for 4-bolt flange units with a UEL insert, as many follow the same dimensional standard. If you have a part number from another manufacturer, we can cross-reference it and quote the equivalent NSK option. Interchangeability depends on shaft diameter, hole spacing, and center height, so confirm these dimensions before replacing.
