The DBH 5339 radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and keep out 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 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, intended for rotating shafts with lubrication. It is a standard replacement part within the line of seals that MR Accesorios Industriales carries.

Typical applications for a seal of these dimensions appear in gearboxes, reducers, centrifugal pumps, electric motors, compressors and belt or chain transmission 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 works on a continuously rotating shaft.

To select it, verify that the shaft and housing diameters match the values on the product page. The lip must ride on a ground shaft surface free of marks; if there is wear, it is advisable to evaluate a repair sleeve. The 8.00 mm height defines the axial space available in the housing. During installation, lubricate the lip with the same grease or oil used in the equipment and avoid striking or inverting it, because that reduces the seal's service life.
