This NTN 4-bolt flange bearing unit pairs a cast iron housing with a self-aligning insert bearing, giving you a compact mounted assembly for supporting rotating shafts on flat surfaces. Four bolts hold the flange in place, which makes installation straightforward on frames, panels and structural steel. It is a practical choice for power transmission on industrial equipment where space is limited and alignment is not perfect.
The UELF code identifies the 4-bolt flange housing series. The digits that follow tell you the size: UELF204-012D1W3 fits a 12 mm shaft, and UELF205-100D1W3 fits a 1 inch shaft. The D1 suffix refers to the insert type, while W3 indicates a sealing variant. When a hyphen appears, as in UELF206-101D1W3, the number after it gives the exact shaft size in inches or millimeters. Reading the code this way helps you order the right unit the first time.
You will find these units on conveyors, belts, elevators, mixers, mills and other process equipment. The 4-bolt flange simplifies mounting on sheet metal or structural frames, which is why they show up in food, cement, mining and agro-industrial plants, as well as in pumping equipment and road machinery. The self-aligning insert absorbs small misalignments and keeps maintenance simple.
To select the correct housing, confirm the shaft diameter and the fastening arrangement you need. The W3 seal is intended for dusty or damp conditions with particles in the air. The insert arrives pre-lubricated, but in demanding applications you should check lubrication on a regular schedule. During mounting, seat the flange properly and tighten the bolts evenly to prevent distortion. Keeping the shaft aligned with the bearing is essential for long service life.
NTN housings interchange with other brands that use the same dimensional nomenclature. If you have a code from another manufacturer, we can identify the equivalent. We can also quote a replacement if you provide the shaft dimensions and the distance between the flange holes. Interchangeability depends on standardized dimensions, not on the code alone.
To request a quote for a 4-bolt flange housing with insert bearing, send us the UELF code or your shaft dimensions on WhatsApp or by email. Our team replies promptly and can suggest equivalents or help you choose the right variant for your application.

Frequently asked questions
- What does the suffix D1W3 mean in a UELF housing?
- The D1 suffix identifies the insert type with its sealing and fastening characteristics. W3 indicates a reinforced sealing variant for environments with dust or moisture. Together they define the insert bearing configuration.
- How do I choose the UELF housing for my shaft?
- You need the shaft diameter and the type of fastening. The UELF code includes the size: for example, UELF205 is for a 25 mm shaft. If your shaft is in inches, the code shows it with a hyphen and three digits. Send us that data and we will quote you.
- Are NTN housings compatible with other brands?
- Yes, NTN housings follow standardized dimensions, so they are interchangeable with other brands that respect the same flange and shaft dimensions. If you send us the code from another brand, we can tell you the NTN equivalent.
