The SEALMASTER SPB series pillow block is a rigid housing designed to mount bearings and secure them to a flat base. It is used when the transmission needs a stable and aligned support, for example on conveyor shafts, fans or process machines. Its construction allows it to absorb moderate radial and axial loads, and facilitates mounting and dismounting of the bearing without damaging the seat. MR Accesorios Industriales supplies this line with standard sizes for different applications.

The SPB series designation is read by its structure: SPB identifies the pillow block, the number that follows indicates the shaft diameter in millimeters (for example, SPB-40MM-2 for 40 mm) and the last digit indicates the design variant or number of mounting holes. Thus, SPB-45MM-2, SPB-50MM-2 and SPB-55MM-2 share the same construction concept, changing only the shaft size. This nomenclature allows quick identification of the spare part or the complete unit.

In Argentine industry, SPB pillow blocks are used in grain conveyors, food plants, flour mills, pumping equipment and ventilation systems. They also appear in road and agricultural machinery, where the robustness of the housing and the possibility of mounting bearings of different brands are key to keeping production running without interruptions. They are common in applications with horizontal shafts that require firm support and easy maintenance.

To select the right pillow block, take into account the shaft diameter, the type of bearing to be mounted and the environmental conditions. If there is dust, humidity or frequent washdowns, additional sealing is advisable. Check the alignment between pillow blocks to avoid parasitic loads and ensure adequate lubrication of the bearing. Mounting must be done on a rigid, flat base, with bolts tightened according to the recommended torque to avoid deformation.

SEALMASTER SPB series pillow blocks are interchangeable with other brands that handle standard sizes, as long as the shaft diameter and the distance between holes match. When requesting a quote, indicate the complete part number and, if possible, the main dimensions.
