SEALMASTER MH series insert bearings are ball bearings with an extended inner ring that lock onto the shaft with set screws. They fit into split or solid housings and are commonly found in conveyors, fans, and agricultural equipment where rotation needs to be smooth and alignment straightforward. MR Industrial Accessories LLC supplies this line and helps you match the right variant to your application.
The code breaks down simply: MH followed by a number for the bore diameter, and often a trailing letter that indicates a sealing or locking variation. For instance, MH-20R is a 20 mm bore insert, with the R marking a particular seal or configuration. Locate the full code on your unit, and we will quote that exact reference.
You will see these inserts in belt conveyors, bucket elevators, mixers, fans, and process equipment across food, chemical, and materials operations. Feed mills, aggregate plants, and packaging lines rely on them because mounting is quick and maintenance is uncomplicated.
When choosing an insert, confirm the shaft diameter, whether the load is radial, axial, or combined, and the operating environment. Sealing matters: for dusty or damp conditions, go with a contact seal version. Install on a clean, burr-free shaft and tighten the set screws with a torque wrench. This series often comes pre-lubricated for life, but high temperatures or speeds may call for a different grease.
SEALMASTER inserts interchange with other brands that follow the same series naming and standard dimensions. If you have an insert from another manufacturer, send us the code and key dimensions—shaft diameter, overall width, and distance between locking centers—and we will point you to a compatible option from our catalog.
To request a quote for a SEALMASTER MH series insert bearing, message us on WhatsApp with the full code, such as MH-20R, or with your shaft and housing dimensions. We respond promptly with the reference and sealing choices. We can also assist if you are replacing a worn insert or considering a more robust setup.

Frequently asked questions
- What does the MH designation mean in SEALMASTER insert bearings?
- MH indicates a series of inserts with an extended inner ring and set screw locking. The number that follows is the bore diameter in millimeters or inches, and the final letter distinguishes sealing or design variants.
- How do I determine the dimensions of my insert bearing?
- Measure the shaft diameter where the insert mounts, the overall width of the bearing, and the distance between the housing locking centers. With those measurements and the code on the insert, we can quote the equivalent reference.
- Can I replace an insert from another brand with a SEALMASTER one?
- Yes, provided the main dimensions and locking type match. Send the original insert code and the shaft and housing dimensions; we will identify the compatible SEALMASTER alternative or the option that best fits your needs.
