When a rotating shaft needs a reliable barrier between lubricant and the outside environment, the DBH 9893 radial shaft seal is one option to evaluate. Its sealing lip runs against a 73 mm shaft and seats in a 89.50 mm housing bore, while its 8.00/15.50 mm height gives some flexibility in how deep the housing pocket is. The A 339 designation describes the lip and outer body geometry. MR Industrial Accessories supplies this brand and can help you confirm whether it matches your equipment.

The reference 9893 belongs to the DBH line of radial shaft seals. Reading the size code is straightforward: shaft 73 mm, housing bore 89.50 mm, overall height 8.00/15.50 mm. The seal is press-fitted into the housing and its lip contacts the rotating shaft, holding oil or grease inside while keeping dust, water and particles out. The A 339 design sets the profile of the lip and the outer casing, so it should be checked against the seal you are replacing.

Seals in this size range turn up in gearboxes, reducers, centrifugal pumps, transmission shafts and similar industrial machinery. In every case the seal acts as a dynamic barrier: it stays with the housing while the lip rides on the lubricated shaft. Shaft condition matters, so the surface should be ground and free of grooves or scoring. The housing bore also needs the correct diameter and enough depth to accept the 8.00/15.50 mm height.

Before ordering, confirm that the shaft measures 73 mm and the bore measures 89.50 mm. The 8.00/15.50 mm height means the seal can sit in housing pockets of different depths within that range. When installing, coat the lip with lubricant, avoid impact on the sealing edge and keep the spring facing the side where the fluid is retained. If the shaft shows wear, a seal with an auxiliary lip may be worth considering.

For an equivalent, the fastest route is to send the code 9893 or the three key dimensions: shaft diameter, housing bore and height. With that information we can check alternatives within DBH or in other brands we supply. We can also advise if the A 339 design does not correspond to your original seal and a different variant is required.
