With dimensions of 31.75 mm shaft, 50.80 mm housing and 11.11 mm height, and an Mz design, it is a reliable solution for equipment operating under demanding conditions. MR Accesorios Industriales carries this official brand and advises you so you choose the right seal.

This item is a radial shaft seal from the DBH brand, identified with the code 5939. Its dimensions are: shaft diameter (d) 31.75 mm, housing diameter (D) 50.80 mm and height (h) 11.11 mm. The Mz design corresponds to a configuration with a sealing lip and a spring that ensures continuous contact on the shaft. It is manufactured with elastomers resistant to oils and greases, and a metal case that gives it rigidity for press fitting. It is a key part for maintaining sealing in gearboxes, pumps and motors.

Typical applications for this seal include gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. In all these cases, the seal prevents lubricant leaks and the entry of contaminants, extending the service life of bearings and gears. It is commonly found in industrial machinery, agricultural equipment and vehicles. Its compact size and Mz design make it suitable for 31.75 mm shafts rotating at moderate and high speeds.

For correct installation, verify that the shaft diameter and housing match the indicated dimensions. The shaft must be clean, free of burrs and scratches, and lubricated before inserting the seal. The lip face must point toward the lubricant side. When installing, press evenly on the outer circumference, never on the lip. If the shaft shows wear, consider using a seal with an auxiliary lip or a wear sleeve. Selection must take into account speed, temperature and the type of fluid to be retained.
