The NTN Y-bearing flange unit is a flange unit that combines an insert bearing with a cast iron or stamped steel housing. It is used to support rotating shafts in equipment where quick mounting and simple alignment are required, such as conveyor belts, fans or mixers. MR Accesorios Industriales sells this line with the backing of a leading brand, and advises you on choosing the right configuration for your application.

The designation of this series is read in blocks: FD indicates the flange unit with a disc, followed by a number that indicates the size of the insert bearing, as in FD209TTRMN/3AS or FD211TTRMN/3AS. The letters TTRMN identify the insert type and its sealing features, while /3AS refers to a specific design variant. Knowing these suffixes lets you order the exact spare part or the complete unit without confusion.

These units are used in the food, chemical, textile and transport industries in Argentina. They are found in belt conveyors, bucket elevators, agitators, blowers and machine tools. Their flange design makes mounting on sheet metal or structures easy, and the insert with set screws allows the shaft to be fastened quickly. MR Accesorios Industriales quotes the part number you need to keep your equipment running.

To select the correct unit, take into account the shaft diameter, the type of load and the environmental conditions. The insert's sealing defines the protection against dust and moisture: choose a design with a suitable seal if there are frequent washdowns. Factory lubrication can be supplemented with periodic greasing depending on the duty cycle. Check the alignment between the housing and the shaft to avoid additional stresses and extend the bearing's service life.

Flange units with insert bearings are interchangeable between brands if the critical dimensions match: shaft diameter, hole spacing and disc diameter. When replacing a unit, compare these values with the original part or consult our technical team. In many cases, the original manufacturer's designation guides the equivalence, but it is always advisable to validate the dimensions before mounting.

You can also send us a photo of the part or the shaft and housing dimensions. At MR Accesorios Industriales we reply promptly with the quote and the technical information you need.
