The DBH 5353 oil seal is a single-lip radial seal that mounts in the housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. With a 52 mm shaft, 75 mm housing and 12 mm height, it is a common size in gearboxes, pumps and power transmission equipment.

This item is a DBH radial oil seal with the designation 5353, with the following dimensions: shaft diameter (d) of 52 mm, housing diameter (D) of 75 mm and height (h) of 12.00 mm. The design is Lx, that is, a single sealing lip with an outer metal case. The rubber lip bears on the shaft and the outer edge of the case fits by interference in the housing. That combination is what defines the seal: the elastomer wipes the lubricant inward and the metal supports the part without deforming.

Seals of this size are used in gearboxes, centrifugal pumps, electric motors, rollers and power transmission equipment. They also appear in older or imported machines where the size is not the usual one. In all those cases they perform the same function: preventing oil or grease from escaping through the shaft passage and keeping the environment from entering the bearing or gear. If the seal is worn out, the first thing noticed is a loss of lubricant and, over time, premature bearing wear.

To install it, check that the shaft has no burrs or marks in the contact area and that the housing is clean and free of dents. Lubricate the lip with the same grease or oil as the equipment before inserting it, and seat the seal with a tube or press that bears evenly on the metal case, never on the lip. If the shaft shows wear, consider a wear sleeve or a seal size with the lip in a different position. The selection depends on the type of lubricant, the temperature and the shaft speed.

If you need an equivalent, send us the part number 5353 along with the shaft and housing dimensions. You can also send us a photo of the old seal or the equipment drawing. With that data we look for the exact size within the DBH line and other brands we sell. If the Lx design is not the right one for your application, we review it with you before requesting a quote.
