The DBH 5669 radial shaft seal is a lip seal designed to stop lubricant from escaping and keep contaminants out of rotating shafts. Its dimensions of 18 mm shaft diameter, 31.75 mm housing diameter and 3.57 mm height make it suitable for tight spaces where a reliable barrier is needed. It is a wear part that should be replaced at the first sign of leakage or noise.

This item is a radial shaft seal from the DBH brand, identified by part number 5669. Its dimensions are 18 mm shaft diameter (d), 31.75 mm housing diameter (D) and 3.57 mm height (h). The Mt design corresponds to a configuration with a single sealing lip and metal case, intended for press fitting into cylindrical housings. It is a compact, low-profile part that seals against the shaft and against the housing bore.

It is used in equipment with continuous rotation and the need to retain oil or grease: small electric motors, gearboxes, pumps, fans, transmission shafts and low-power machinery. It also appears in automotive, agricultural and industrial applications where axial space is limited. Its function is to protect bearings and gears from dust, water and particles, extending the service life of the assembly.

To select the correct seal, verify that the shaft and housing diameters match the values indicated. Mounting should be done with a clean shaft, free of burrs or marks, and with the lip lubricated before inserting it. It is important that the housing has the appropriate chamfer so the lip is not damaged during installation. If the shaft shows wear, consider a nearby size or a seal with an auxiliary lip.
