A take-up housing from the SEALMASTER STH line keeps chain and belt drives at the right tension by letting the shaft position be adjusted. It combines a mounted bearing with a housing that slides or shifts as the drive stretches or wears. MR Industrial Accessories LLC supplies this series to maintenance and purchasing teams, and can help you match the correct variant to your equipment.

Reading an STH part number starts with the letters, which mark the take-up housing family. The digits that follow describe the shaft diameter and how the housing is built. Two references such as STH-14-6 and STH-14-9 therefore share a shaft size but not the same width or mounting style, and the same logic applies wherever the leading number repeats. The trailing suffix sets the center distance and the tensioning range, so the series table is the reliable way to confirm what each code means.

Typical installations include belt conveyors, drag belts, chain elevators, bottling lines and process equipment in food, chemical and bulk material plants, where keeping tension steady prevents chain skip and early wear. Because the bearing position can be moved without tearing down the whole assembly, adjustment is straightforward during routine maintenance.

Selection comes down to three inputs: shaft diameter, chain pitch or belt type, and the tensioning travel your drive needs. Confirm as well that the housing fits the base or rail it bolts to. Lubricate the insert at the interval the manufacturer specifies, inspect the seal for dust or moisture entry, and align the housing with the rest of the drive to get the most from the bearing.

SEALMASTER mounted bearings may be swapped with other brands built to the same mounting standard, though housing dimensions and hole positions are not always identical. Compare the full part number and the critical dimensions before replacing a take-up housing. MR Industrial Accessories LLC can identify a suitable equivalent from its housing and insert bearing range.
