The NTN SEST tensioner housing is a mounted unit that combines an insert bearing with a tensioner housing. It is used to maintain correct tension in transmission chains and belts, and to guide their path. Its design allows direct mounting on shafts and fastening in different positions. MR Accesorios Industriales sells this line as part of its range of bearing housings, with technical advice to choose the right unit.
The SEST designation identifies NTN tensioner housings. The number that follows indicates the size: SEST201, SEST202, SEST203 and SEST204 correspond to increasing sizes. Suffixes with a hyphen, as in SEST204-12 or SEST205-16, indicate variants of shaft diameter or fastening. To correctly interpret each code, refer to the dimension table in the NTN catalogue or ask us with the full code.
These housings are used in conveyors, belts, elevators, agricultural machinery and industrial equipment where chains or belts need to be tensioned. In Argentina, they are common in the food, cement, mining and processing industries. Their function is to absorb tension variations and extend the life of the transmission.
To select the housing, check the shaft diameter, the chain or belt pitch and the type of fastening. The insert bearing usually comes pre-lubricated and with seals that retain grease and block contaminants. During mounting, ensure correct alignment to avoid axial loads. Periodic lubrication and clearance checks are key to long-lasting performance.
NTN manufactures these housings under international standards. If you need to replace a unit from another brand, we can help you find the right equivalent. Bring us the code of the original part or the shaft dimensions and center distance, and we will quote the corresponding option.
