SEALMASTER ST-T take-up frames are mounted units that pair an insert bearing with a cast iron housing. They are used where a drive needs consistent tension on a chain, belt, or conveyor belt while tolerating minor misalignment. MR supplies this line and can help you match the frame to your shaft and mounting arrangement.

The ST-T code works like this: ST comes first, then a number that tells you the shaft size in sixteenths of an inch, and the T at the end means it is the take-up style. So ST-12T fits a 12/16" (3/4") shaft, ST-15T a 15/16" shaft, ST-16T a 1" shaft, ST-18T a 1-1/8" shaft, ST-19T a 1-3/16" shaft, ST-20T a 1-1/4" shaft, ST-22T a 1-3/8" shaft, and ST-23T a 1-7/16" shaft. The T is what separates this version from other housings in the same family.

You will find these take-up frames on belt conveyors, bucket elevators, packaging lines, and chain or belt drives. In food, cement, mining, port, and agricultural plants, they are common where belt tension has to be adjusted often. The housing stands up to dusty, vibrating conditions, and the insert bearing simplifies mounting on solid shafts.

When you select a model, look at the shaft diameter, the radial and axial loads the system will see, and the sealing needed for the environment. During installation, line up the frame with the drive, fasten the base, and set the take-up so you get the right tension without overloading the bearing. Follow the manufacturer's lubrication instructions and check it regularly to avoid premature failures.

SEALMASTER take-up frames can interchange with other brands that use a similar mounting, as long as the shaft diameter, hole spacing, and center height are the same. For a quote, send the full part number and key dimensions; MR will point you to a compatible alternative or discuss a custom build. Interchangeability is not decided by the number alone—housing dimensions matter.
