The DBH 5552 oil seal is a radial seal with 53 mm shaft diameter, 68 mm housing bore and 10 mm height, in Mx design. Its function is to retain lubricant inside the assembly and block the entry of dust, water or particles that accelerate wear on bearings and bushings. It is press-fitted into the housing and runs on the shaft with a flexible lip that maintains contact. It is a wear part: it is replaced when oil loss or dirt ingress appears.

This item is a DBH 5552 radial shaft seal, identified by its designation 5552. Its dimensions are 53 mm shaft diameter, 68 mm housing bore diameter and 10 mm height, in Mx design. The Mx design corresponds to a single-lip seal with spring, suitable for lubricated rotating shafts. The 5552 nomenclature follows the DBH coding system: the first two digits are associated with the shaft diameter and the remaining ones with the housing bore and height. To confirm interchangeability, always compare all three dimensions and the lip type against the original part.

It is used in gearboxes, pumps, electric motors, conveyor rollers and power transmission equipment where a shaft rotates inside a lubricated housing. It also appears in applications exposed to dust or splashing, where the seal prevents the contaminant from reaching the bearing. In food, textile and process plants it is commonly found in mixers, agitators and conveyors. The choice of lip and spring material depends on temperature, peripheral speed and the fluid to be retained.

To install a radial shaft seal, the housing must be clean, free of burrs and with the lead-in chamfer in good condition. Lubricate the lip with the same grease or oil used in the equipment before seating it and press it in evenly, without striking the lip. Check that the spring is on the fluid side and that the shaft has no grooves or wear in the contact area. If the shaft is marked, consider a wear sleeve or a nearby size. Speed, temperature and the type of lubricant determine the appropriate compound.

If you need an equivalent or a close size, send us the full part number, the three dimensions (shaft, housing bore and height) and a photo of the part. With that data we review alternatives within the DBH line or from other brands we carry, always respecting the mounting dimensions. We can also guide you if the original seal has a double lip, a dust lip or a particular geometry. The more precise the information, the faster we reach the right option.
