A tensioner housing from the SEALMASTER STMH line pairs a cast housing with an insert bearing, giving you a take-up point that keeps chains, belts and conveyor belts under the tension they need. It suits drives and conveyors where misalignment and radial load are part of daily operation. MR Industrial Accessories supplies this line in the standard inch sizes, and our team can help you match the right unit to your shaft.

Reading the STMH code is straightforward once you know the rule: the letters stay fixed and the number that follows gives the shaft diameter in inches, counted in 1/16" steps. STMH-16 takes a 1" shaft, STMH-20 takes 1-1/4", STMH-24 takes 1-1/2" and STMH-32 takes 2". That suffix is not a catalog sequence; it is the bore of the insert, which is why getting the number right is the first thing to check before mounting.

You will find these units on belt conveyors, bucket elevators, packaging belts and chain or belt drive lines. In food processing, cement, mining and aggregates, they hold tension at points where vibration and continuous load call for a sturdy, self-aligning support.

Selection comes down to three things: shaft diameter, the nature of the load (radial, axial or a combination) and where the unit will sit. The insert seal tells you how much protection you get from dust and moisture, so a labyrinth or higher-efficiency seal makes sense in dirty surroundings. Use the lubricant the manufacturer specifies and line the housing up with the shaft during mounting so you do not introduce unnecessary stress.

STMH SEALMASTER tensioner housings interchange with other brands that follow the same inch size naming, including comparable series from SKF, NTN or Timken. What governs the swap is the shaft diameter and the insert mounting type, not the commercial part number. Replacing an existing housing? Send the number stamped on it or the shaft size.
