The DBH 8894 radial shaft seal is a lip seal mounted between a rotating shaft and a fixed housing to retain lubricant and block the entry of dust, water or particles. Its designation 8894 corresponds to a specific size: 40 mm shaft, 56 mm housing and 7 mm height, with Lx design. It is used in gearboxes, pumps, electric motors and power transmission equipment where bearings must be protected and leaks prevented.

This item is a seal from the DBH line, identified with part number 8894. Its dimensions are 40.00 mm shaft diameter, 56.00 mm housing diameter and 7.00 mm height. The Lx design indicates a single lip configuration with spring, intended for rotating shafts with permanent lubrication. The elastomeric lip bears on the shaft and the spring maintains contact pressure; the outer metal body ensures the fit in the housing. It is a standard replacement part within the radial seal category.

Typical applications appear in equipment with continuous rotary motion: gearboxes, centrifugal pumps, electric motors, speed reducers and conveyor rollers. In all these cases the seal serves two functions: retaining the oil or grease inside the assembly and blocking the entry of external contaminants. When the seal wears, it begins to lose lubricant and the bearing becomes exposed to premature failure. That is why it should be checked every time the equipment is disassembled.

To install a seal, verify that the shaft has no burrs or deep marks in the contact area, and that the housing is clean and free of deformation. The lip is lubricated before insertion and is pressed in with a tube of suitable diameter, without striking the metal body. Selection depends on the type of lubricant, the working temperature and the shaft speed; if these data are not defined, consult the manufacturer's product page. The Lx design is a common reference for general applications.

If you need a nearby size or an equivalent, the most practical approach is to send the part number 8894 together with the shaft, housing and height dimensions. With these data, an alternative can be found within the same series or from another brand that MR carries. A photo of the old seal showing the markings also helps. The more complete the information, the faster the correct part is found.

MR Accesorios Industriales carries the DBH brand as part of its line of seals and radial shaft seals.
