The SEALMASTER TB series pillow block with insert bearing is a foot-mounted bearing unit: the unit combines a cast iron housing and an insert bearing with a spherical outer ring, which allows small misalignments to be compensated. It is used to support shafts in equipment where lubrication and sealing are already resolved at the factory. MR Accesorios Industriales sells this line in Buenos Aires, Argentina, and advises you on choosing the right size.
The TB series designation is read by the number that follows the hyphen: TB-8, TB-9, TB-10, TB-11, TB-12, TB-14, TB-15 and TB-16 are examples of this nomenclature. That number identifies the size of the bracket and the insert bearing it houses. The letters TB correspond to the foot-mounted housing type with two mounting holes. To select, have the shaft diameter and mounting dimensions on hand; with that data we will quote the exact reference.
These brackets are used in conveyors, belts, elevators, mixers, fans and process lines in food, chemical, cement and aggregate processing plants. In Argentina they are common in material handling equipment and agricultural machinery. The cast iron housing withstands the weather and the insert bearing comes lubricated and sealed, which simplifies maintenance in dusty or humid environments.
To choose well, verify that the shaft diameter matches that of the insert and that the distance between the bracket holes is compatible with the base. The spherical outer ring of the insert allows slight misalignments to be corrected during installation. Tighten the screws evenly and check that the shaft turns freely. If the equipment works with axial load, consult us: we will indicate the appropriate variant.
SEALMASTER is a brand that MR Accesorios Industriales sells. There are other lines of pillow block bearings on the market, with standardized dimensions that in many cases allow direct replacement. Interchangeability depends on the series and the shaft diameter. If you send us the original part number or the bracket dimensions, we will indicate the compatible alternative from our catalog.
To move forward with your inquiry, send us via WhatsApp the part number shown on the equipment or the main dimensions: shaft diameter, distance between holes and height to center. With that we will quote you promptly. MR Accesorios Industriales has more than 80 years supporting Argentine industry from Buenos Aires.

- How do I choose the right bracket for my equipment?
- You need the shaft diameter, the distance between mounting holes and the height to center. With that data we will indicate which reference from the TB series fits. If you have the original part number, even better: we will cross-reference it with our line.
