The MP series Y-bearing pillow block with insert bearing is a mounted pillow block assembly that combines an insert bearing unit with a cast housing. It is used to support rotating shafts in equipment where simple fastening and adequate alignment are required. MR Accesorios Industriales sells this SEALMASTER line, a brand that MR carries, with references such as MP-15, MP-16 and MP-19.
The MP series designation is read as a numeric code preceded by the letters MP. Each number, as in MP-15, MP-16, MP-19 or MP-20, identifies a specific size and configuration within the family. Any suffixes that may appear in the designation indicate construction variants, such as the sealing type or the method of locking to the shaft. To choose the correct reference, take into account the shaft diameter, the load type and the environmental conditions.
These pillow blocks are used in a wide variety of industrial applications in Argentina. They are found in conveyors, belts, elevators, mixers, fans and process equipment. They are also common in the food, chemical and cement industries and in aggregate processing plants. Their pillow block design allows mounting on steel structures or concrete bases, facilitating maintenance and replacement.
To select the right pillow block, consider the shaft diameter, the radial and axial load, and the working conditions. Verify the sealing type: units with a single lip seal are suitable for environments with moderate dust, while versions with multiple seals offer greater protection. During mounting, ensure correct alignment between the pillow block and the shaft to avoid additional loads. Lubrication must be the one specified by the manufacturer and renewed according to the duty cycle.
SEALMASTER MP series pillow blocks can be interchanged with equivalent units from other brands that follow similar dimensional standards. When looking for an alternative, compare the main dimensions: shaft diameter, distance between mounting holes, height to center and locking type. MR Accesorios Industriales advises you to find the option compatible with your equipment, without the need to modify the existing structure.
