The DBH 5681 is a radial shaft seal that keeps oil or grease contained where a rotating shaft exits a housing. Its dimensions are 35 mm for the shaft, 52 mm for the housing bore and 8.80 mm for the height, and it uses the Mz design for the lip and metal case. MR Industrial Accessories supplies this line and can help confirm the size before you request a quote.

The code 5681 sits within the DBH range of radial shaft seals. Selection comes down to three measurements: shaft 35 mm, housing 52 mm and height 8.80 mm. The Mz design describes how the sealing lip and outer case are put together. Get any of those measurements wrong and the seal will not sit correctly, which reduces how well it seals.

You will find this seal in gearboxes, centrifugal pumps, electric motors, mixers and other power transmission equipment, wherever a shaft turns inside a lubricated housing. It also suits locations exposed to dust or water, since it keeps contaminants away from the bearing. Before fitting a replacement, inspect the shaft and housing for wear.

During installation, check that the shaft contact area is smooth and free of burrs, and that the housing bore is clean. Coat the lip with the same oil or grease used in the machine, then press on the outer edge evenly, keeping force away from the lip. If the shaft has a deep groove, a seal with the lip positioned differently may be a better choice.

To find an equivalent or another size, message us the code 5681 together with your shaft, housing and height measurements, or a photo of the old seal. The marking on the seal itself also helps. With that information we look for an alternative in the DBH line or in other brands we carry and send you a quote.
