The STH take-up housing is a mounted bearing with a take-up housing, designed to maintain correct tension in chain or belt drives. The SEALMASTER STH series is used in applications where the shaft must move to compensate for stretch or wear. MR Accesorios Industriales sells this line with technical advice so you can choose the right variant for your equipment.

The STH designation is read as a family of take-up housings: the letters STH identify the type, and the numbers that follow indicate the shaft diameter and the housing configuration. For example, STH-14-6 and STH-14-9 share the same shaft diameter but differ in width or mounting type; the same applies to other part numbers that share the first number. The final suffix makes it possible to adapt the housing to different center distances and tensioning needs. To correctly interpret each part number, it is advisable to consult the series table.

These take-up housings are used in belt conveyors, drag belts, chain elevators, bottling lines and process equipment in food, chemical and bulk material plants. In Argentina, they are common in the oilseed, meatpacking and aggregate processing industries, where constant chain or belt tension is critical to prevent skipping and premature wear. Their design allows the bearing position to be adjusted without disassembling the entire assembly.

To select the correct STH housing, take into account the shaft diameter, the chain pitch or belt type, and the tensioning travel you need. Check that the housing is compatible with the base or rail where it is mounted. Lubrication of the insert is essential: follow the frequency recommended by the manufacturer and check the sealing to prevent dust or moisture ingress. Careful alignment between the housing and the rest of the drive extends bearing service life.

SEALMASTER mounted bearings can be interchanged with other brands that follow the same mounting standard, but housing dimensions and hole locations may vary between manufacturers. Therefore, before replacing a take-up housing, compare the complete part number and the critical dimensions.
