MR Accesorios Industriales supplies this brand and helps you verify the size before requesting a quote.

This item is a seal from the DBH line, identified by code 5159. Its published attributes are: shaft diameter (d) 25.40 mm, housing diameter (D) 37 mm, height (h) 7.50 mm and Lz design. The Lz design corresponds to a seal with a sealing lip and standard configuration for general applications. Before mounting it, compare these three dimensions with your equipment's housing and shaft: they determine whether the seal seats correctly and seals as it should.

Typical applications for a seal of this size include gearboxes, centrifugal pumps, electric motors, compressors and belt or chain drive equipment. In all cases it performs the same function: keeping oil or grease inside the assembly and preventing the entry of contaminants that accelerate wear on bearings and gears. It is also used as a closure on fan, mixer and conveyor shafts, where the environment often contains dust or moisture.

To select and mount a radial shaft seal, verify that the shaft diameter, housing diameter and height match those of the seal. The lip must be lubricated before insertion, and a mounting tool should be used to avoid damaging it. Check that the shaft surface has no burrs or scratches, and that the housing is clean and free of deformation. If the shaft shows wear, consider a neighboring size or a seal with an auxiliary lip.

If you need an equivalent or a neighboring size, send us code 5159 or the dimensions of your current seal: shaft diameter, housing diameter and height. With that data we can look for an alternative within the same DBH line or another brand we supply. We can also advise you if the Lz design is not suitable for your application and you need a different lip configuration or material.
