For machinery that runs on rotating shafts with mainly radial loads and less-than-perfect alignment, the SEALMASTER TBMH pillow block with insert bearing is a common choice. This mounted unit appears in conveyors, fans, belts and process equipment. MR Industrial Accessories supplies this line to customers across the United States and in several Latin American countries, and can help you match the right part number to your shaft diameter and mounting style.

Reading the TBMH code is straightforward: the letters indicate the pillow block family with insert bearing, and the number after the hyphen tells you the shaft size the insert is bored for. That is why TBMH-16, TBMH-19, TBMH-20, TBMH-23, TBMH-24, TBMH-27 and TBMH-31 all belong to the same series but fit different shafts. When you order, the full part number including that number is what identifies the exact unit.

You will find these pillow blocks in a wide range of plants: food processing, tanneries, mills, water treatment, plastics and packaging lines. They support shafts on belt and chain conveyors, centrifugal fans, mixers, screens and transmission equipment where a sturdy, easy-to-mount support is needed. The base bolts to a machine bed or structural profile with two fasteners, which keeps installation and replacement simple on the plant floor.

Selection starts with the shaft diameter you need to support and the type of load. If the load is purely radial, a TBMH pillow block is a good fit; if there is significant axial load, consider a different configuration. Also look at the insert seal, because in dusty, wet or chip-heavy environments the seal affects service life. During mounting, set the base on a flat surface, tighten the fastening bolts and check shaft alignment before start-up. Lubricate the insert through the provided channel, following the manufacturer's recommended frequency for your application.

Pillow blocks with insert bearings can be interchanged between brands by shaft number and base configuration, but not by internal part number, since each maker uses its own nomenclature. If your equipment currently runs a pillow block from another brand, the key data are the shaft size, the insert outer diameter and the distance between base holes. With those dimensions, MR Industrial Accessories can point you to the compatible alternative in the SEALMASTER line or the option that best suits your mounting.
