The DBH 8355 is a radial shaft seal that keeps lubricant in and contaminants out where a shaft passes through a housing. With a 55 mm shaft, 90 mm bore and 12.50 mm height, it fits medium-sized rotating equipment. As a wear item, it should be replaced when the lip hardens or leaking starts, before the bearing suffers damage.

This seal carries the designation 8355 and the Kz design, which means a single lip with a retaining spring. The flexible lip contacts the rotating shaft while the metal outer case presses into the housing bore. It is built for continuous duty with oil or grease.

Typical installations include gearboxes, pumps, electric motors, line shafts, rollers and process machinery. In these spots, splashing, dust or moderate moisture can reach the seal, and a correct choice helps prevent bearing wear and unplanned downtime from oil loss.

Before mounting, make sure the shaft is clean and free of burrs or tool marks, and that the housing bore is smooth. Apply lubricant to the lip, then press the seal in squarely and fully seated. If the shaft shows a wear groove, consider a seal that positions the lip on a fresh area. Speed, temperature and lubricant type guide the final selection.

For a different size or a replacement, send the code 8355 or the shaft, bore and height measurements, plus a photo of the part and the mounting area. We can review options within the same radial shaft seal category and confirm a fit without housing changes. We also verify whether the Kz design matches your equipment.
