A SUCT unit pairs an insert bearing with a cast tensioner housing that has a sliding base. That base lets maintenance teams shift the unit along its mounting surface so chain, belt or conveyor slack can be taken up without rebuilding the whole assembly. The NTN SUCT line covers both metric and inch shaft sizes, which makes it a practical choice for conveyors, elevators and transmission drives where tension has to be readjusted over time.
Reading the code is straightforward. SUCT is the series prefix, and the digits after it give the shaft size. SUCT205 fits a 25 mm shaft. When the number is followed by a hyphen and a figure, the unit is built for an inch shaft: SUCT205-16 takes a 1 inch shaft (16/16"). A trailing letter can point to a particular sealing or fastening arrangement.
Typical installations include belt conveyors, bucket elevators, packaging lines, farm equipment, mining machinery and food processing plants. In all of them the goal is the same: keep steady tension so the chain or belt does not drift out of line or wear early.
When specifying a unit, work from three points: shaft diameter, locking method (set screw or eccentric collar) and the seal type the environment calls for. During installation, line the housing up with the chain or belt, set the tension, then lubricate the insert bearing to suit the operating conditions. Because the base slides, position can be corrected later without pulling the assembly apart. The mounting surface should be clean and flat to keep vibration down.
NTN SUCT housings follow the same dimensional nomenclature used by other manufacturers, so a unit can often be swapped when shaft and housing dimensions line up. The code itself is not what makes the match. If you are holding a part number from a different brand, send it over and the team can identify the corresponding option.

Frequently asked questions
- What does the -16 in SUCT205-16 indicate?
- It marks the inch version: the unit fits a 1 inch shaft (16/16"). The plain SUCT205 code is the 25 mm metric size.
- Which seal should I pick for a dusty plant?
- Dusty or dirty areas call for units with extra contact or labyrinth seals. The NTN SUCT series includes variants with different sealing arrangements, so describe your conditions and the team can point you to the right one.
- Can an NTN SUCT replace a tensioner housing from another brand?
- If the shaft and housing dimensions are the same, yes. Matching is based on those dimensions rather than on the code. Send the original code or the measurements and the corresponding NTN option can be quoted.
