The DBH 5770 radial shaft seal is a lip seal mounted between a rotating shaft and a fixed housing to retain lubricant and block the entry of dust, water or particles. With its dimensions of 30.10 mm shaft, 51.40 mm housing and 11.90 mm height, in Mz design, it is used in gearboxes, pumps, electric motors and power transmission equipment that require reliable, low-maintenance sealing.

This item is a radial shaft seal from the DBH line, identified by part number 5770. Its dimensions are 30.10 mm shaft diameter (d), 51.40 mm housing diameter (D) and 11.90 mm height (h). The Mz design corresponds to a single-lip configuration with spring, intended for rotating shafts with permanent lubrication. The elastomeric lip runs on the shaft and the outer metal case ensures a firm fit in the housing.

Typical applications for a seal of this size include gearboxes, centrifugal pumps, electric motors, compressors, mixers and belt- or chain-driven transmission equipment. In all cases it serves to retain the oil or grease inside the assembly and prevent contaminants from entering and accelerating wear on bearings and gears.

To install it, check that the shaft is within the recommended tolerance, free of burrs and marks, and that the housing has the correct diameter and depth. Lubricate the lip before inserting it and use an installation tube that presses on the case, never on the lip. If the shaft shows wear, consider a neighboring size or a seal with an offset lip.

We can also advise you on the most suitable lip design according to the type of lubricant and the operating speed.
