The NTN SEST take-up housing is a mounted unit that pairs an insert bearing with a take-up housing. It keeps the correct tension on transmission chains and belts and helps guide their path. The unit mounts directly on shafts and can be fastened in various positions. MR Industrial Accessories LLC supplies this line within its bearing housing range and provides technical support to select the right unit.
The SEST code identifies NTN take-up housings. The number after SEST indicates the size, with larger numbers representing larger sizes. A hyphenated suffix, such as in SEST204-12 or SEST205-16, points to a shaft diameter or a mounting variant. To read any code accurately, check the dimension table in the NTN catalog or send us the complete code.
Typical applications include conveyors, belts, elevators, agricultural machinery and industrial equipment where chains or belts require tensioning. These units absorb tension changes and help extend the life of the transmission. You will find them in food processing, cement, mining and other processing plants.
When selecting a housing, confirm the shaft diameter, the chain or belt pitch and the mounting type. The insert bearing generally arrives prelubricated and fitted with seals that hold grease in and keep contaminants out. During assembly, align the unit carefully to prevent axial loads. Regular lubrication and clearance checks support long service life.
NTN produces these housings to international standards. If you are replacing a unit from another brand, we can help you identify a suitable equivalent. Provide the original part code or the shaft dimensions and center distance, and we will quote the matching option.
