The DBH 8727 is a seal with an Mx design, with the dimensions shown on its product page: 40 mm shaft diameter (d), 56 mm housing diameter (D) and 9 mm height (h). The sealing lip runs on the shaft and the outer diameter is press-fitted into the housing. It is a common replacement component in equipment with rotating motion, and its function is to retain lubricant and slow the ingress of dust or water.

It is found in gearboxes, centrifugal pumps, electric motors, rollers and transmission shafts. It also appears in process equipment, industrial washing machines and agricultural machinery. When the seal loses elasticity or the lip wears, it begins to lose lubricant and should be replaced before the bearing or bushing it protects fails.

To install it, verify that the shaft has no burrs or marks and that the sealing surface is clean. Lubricate the lip with the same grease or oil used in the equipment before inserting it. The seal must enter perpendicular to the housing, without direct blows to the lip. If the shaft shows wear, consider a seal with an additional spring.

If you need an equivalent, send us the code 8727 along with the shaft diameter, housing diameter and height. A photo of the old seal or the housing drawing also works. At MR Accesorios Industriales we compare this data with the manufacturer's data sheet to offer you the option that best suits your needs.
