Description

A take-up bracket in the SEALMASTER STMH line pairs an insert bearing with a cast iron housing, and its job on a machine is to hold tension on a chain, a belt or a conveyor belt. It also tolerates a small amount of misalignment in the drive. MR Industrial Accessories LLC supplies this line to maintenance and purchasing teams in the United States and Latin America.
Reading the code helps you order the right piece. STMH names the take-up bracket family that carries an insert bearing. The digits that follow, as in STMH-20R, give the nominal shaft diameter in millimeters. The R marks the version that comes with the insert bearing already mounted. Before you pick a model, have the shaft size and the mounting style your machine accepts on hand.
You will see these units on belt conveyors, bucket elevators, bottling lines, packaging belts and chain drives. Plants that run continuously rely on them to keep slack out of the drive, which is what causes unplanned stops. The housing resists dust and moisture, so it holds up in tough conditions.
For selection, confirm that the shaft diameter matches the number in the designation and that the take-up travel covers your application. At installation, line the unit up with the drive before you tighten it down, grease the insert according to its sealing type, and check axial play. Good alignment cuts vibration and helps the bearing last.
Take-up brackets with insert bearings from different brands can often be swapped when the mounting dimensions, shaft diameter and mounting system line up. When you ask for a quote, send the complete part number and the critical dimensions, and we can point you to a compatible option. Our team helps you make sure the replacement will not affect how your equipment runs.

Frequently asked questions
- What does the number in STMH-20R stand for?
- It is the nominal shaft diameter in millimeters, so STMH-20R fits a 20 mm shaft. The R tells you the unit ships with the insert bearing mounted. Other shaft sizes are covered elsewhere in the STMH series.
- How can I tell whether the STMH bracket fits my equipment?
- Look at three things: the shaft diameter, the distance between mounting centers, and the take-up style your machine takes. Send us those and we will confirm. If they do not match, we can suggest another option from the same family or a different brand.
- What lubrication does this take-up bracket require?
- The insert bearing arrives pre-lubricated. Once in service, follow the manufacturer's guidance based on your load and speed. In dusty or damp areas, pick a sealing option suited to the environment and check lubrication at every maintenance interval.
