The FD211TTRKAN/3AS is a flanged disc unit from the NTN BCA flanged disc unit series. It pairs an insert bearing with a housing that bolts flat to a frame, so a rotating shaft can be supported and aligned with minimal setup work. Maintenance and purchasing teams specify this style of unit for power transmission duties in agricultural, industrial and transport machinery.

Reading a code like FD211TTRKAN/3AS tells you most of what the unit is. The leading letters place it in the disc flange family, the figure in the middle sets the shaft size, and the trailing characters cover seal design and insert details. Because every position in the code carries meaning, the reliable way to confirm a unit is to check it against the full NTN nomenclature rather than guess from the shaft size alone.

Flange mounting is what makes these units practical on site. The housing bolts directly to a structure or frame, which keeps shaft alignment simple and makes replacement a straightforward job when a bearing reaches the end of its service. Typical duties include conveyors, mills, mixers, ventilation equipment and the rotating assemblies found on seeders and harvesters, as well as process lines where the shaft needs firm support and protection from dust and moisture.

Selection comes down to three things: shaft diameter, the nature of the load, and where the unit has to work. The sealing arrangement on the insert determines how well the bearing stands up to contaminants, and codes with contact seals suit dusty or damp locations. Use the lubricant the manufacturer specifies, verify internal clearance before the unit goes on the shaft, and line up the flange with the shaft so the bearing is not carrying avoidable stress.

Interchange between brands is not something to assume. Two units can share a shaft diameter yet differ in sealing, locking method or housing material, so a part number from one maker does not automatically match another. When replacing an existing unit, the complete number from the original part, or the shaft and housing dimensions, gives the surest identification. We quote the NTN number you provide or a compatible alternative.

Send the part number stamped on the unit, or the model you are looking for, by WhatsApp or email and we will come back to you promptly with the matching unit and mounting guidance. If the designation is unclear, a photo of the nameplate or housing is usually enough for us to identify it.
