The DBH 5339 radial shaft seal is a lip seal that is mounted in the housing and closes against the rotating shaft to retain lubricant and stop the ingress of dust, water or particles. Its dimensions are 40.00 mm shaft diameter, 56.00 mm housing diameter and 8.00 mm height, with Lx design. It is used in gearboxes, pumps, electric motors and power transmission equipment that operate with oil or grease.

This item is a DBH 5339 radial shaft seal, identified by its designation 5339 and by the dimensional combination 40.00 x 56.00 x 8.00 mm. The shaft diameter (d) is 40 mm, the housing diameter (D) is 56 mm and the height (h) is 8.00 mm. The Lx design corresponds to a single-lip seal with spring, designed for rotating shafts with lubrication. It is a standard replacement part within the line of seals that MR Accesorios Industriales supplies.

Typical applications for an oil seal of these dimensions appear in gearboxes, reducers, centrifugal pumps, electric motors, compressors and belt or chain drive equipment. In all cases it performs the same function: confining the oil or grease inside the assembly and preventing contaminants from entering from outside. It is also found on fan, mixer and conveyor shafts, where the seal runs on a continuously rotating shaft.

To select it, check that the shaft diameter and the housing diameter match the values on the product page. The lip must bear on a ground shaft surface free of marks; if there is wear, it is advisable to consider a repair sleeve or a nearby size. The 8.00 mm height defines the axial space available in the housing. During installation, lubricate the lip with the same grease or oil as the equipment and avoid hitting or inverting it, because that reduces the service life of the seal.
