This item is a DBH radial shaft seal, identified by the designation 5288. Its dimensions are 25 mm shaft diameter (d), 50 mm housing diameter (D) and 12.00 mm height (h). The Lz design indicates a single lip configuration with spring, suitable for rotating shafts with lubrication. The elastomeric lip seals against the shaft and the outer diameter fits into the housing to prevent leaks. It is a standard replacement part in industrial equipment.

Typical applications include gearboxes, centrifugal pumps, electric motors, speed reducers and conveyor rollers. In all cases, the oil seal protects the bearings from the ingress of dust, water or particles, and prevents the loss of oil or grease. It is also used in power transmission equipment where the shaft rotates at moderate speeds and the service temperature is the usual one in a factory or plant.

To install an oil seal, check that the shaft has no burrs or wear, and that the housing is clean and free of deformation. It is recommended to lubricate the lip with the same grease or oil used in the equipment before inserting it, and to use an installation tool that presses on the outer diameter, never on the lip. The selection depends on shaft speed, temperature and the type of fluid to be retained; if you have any doubts, consult us with your equipment data.

If you need an equivalent or a nearby size, send us the full part number of the original oil seal, the shaft, housing and height dimensions, and a photo of the part.
