The NTN Y-bearing with insert bearing is a flanged unit that pairs an insert bearing with a metal housing. It mounts quickly on shafts and fastens with bolts, making it a practical choice for guiding and supporting rotating shafts where alignment needs to stay simple. MR Industrial Accessories supplies this line and can help you confirm the right reference for your equipment.
Reading the code helps you pinpoint the unit you need. The first letters identify the unit type, the digits that follow indicate the shaft diameter, and the suffixes cover sealing, fastening or material options. Take FD209TTRJN/3AS: it is a flanged unit for a 45 mm shaft with reinforced sealing and a defined configuration within the BCA® FLANGED DISC UNIT SERIES.
These units appear in conveyors, belts, elevators, mills, mixers and process equipment across food, chemical, cement and material handling operations. Their flanged design simplifies installation on metal structures and allows fast replacement when maintenance windows are tight.
Selection comes down to shaft diameter, load type, rotation speed and the surrounding environment. Match the sealing to dust, water or chemical exposure, and keep lubrication and alignment in check to support service life. The flange needs a flat, firm mounting surface to prevent deformation and vibration.
Y-bearing units with insert bearings can be interchanged between brands when the critical dimensions line up: shaft diameter, hole spacing, outer diameter and width. During replacement, confirm that tolerances and sealing type also match. If you are working from another brand's part number, we can help you find the equivalent.

Frequently asked questions
- What does the designation FD209TTRJN/3AS indicate?
- The initial letters indicate the flanged unit type, the numbers indicate the shaft diameter, and the suffixes indicate sealing and fastening variants. In this case, it corresponds to a unit for a 45 mm shaft with reinforced sealing. With the complete part number we can quote the exact reference.
- How do I choose the right sealing for my application?
- The sealing depends on the environment: for dust and dirt, choose single-lip seals; for water or frequent washdowns, double seals or seals with additional protection. If chemical agents are present, ask us about special materials. The correct selection helps prevent contamination and supports bearing life.
- Can I replace a unit from another brand with this NTN one?
- Yes, if the critical dimensions match: shaft diameter, hole spacing, outer diameter and width. Also verify the sealing type and tolerances. If you send us the part number of the original unit, we will indicate the NTN equivalent that best fits.
