The DBH 8660 radial shaft seal is a lip seal that is mounted in a component housing and seals against the rotating shaft to retain lubricant and stop dust, water or particles from entering. Because of its dimensions — 35 mm shaft, 55 mm housing and 8 mm height — it is used in gearboxes, pumps, electric motors and power transmission equipment that need a reliable, low-maintenance seal.

This item is a DBH 8660 radial shaft seal, with a 35 mm shaft diameter, 55 mm housing diameter and 8.00 mm height. The Lx design corresponds to a single-lip seal with a spring, intended for lubricated rotating shafts. The 8660 nomenclature identifies the size within the DBH line, and the assembly is press-fitted into the housing, with the lip resting on the shaft. It is a wear part: when the lip loses its elasticity or becomes marked, it starts to leak oil.

Typical applications for a seal of these dimensions are gearboxes, reducers, centrifugal pumps, electric motors, compressors and belt- or chain-driven transmission equipment. It also appears in machine tools, washing equipment and conveyor systems. In every case it performs the same function: separating the lubricated side from the environment, preventing leaks and protecting bearings and gears from the entry of contaminants that accelerate wear.

To install it correctly, check that the shaft has no burrs or marks in the lip area and that the housing is clean and free of deformation. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and do so with a tube or socket that presses on the outer ring, never on the lip. If the shaft shows wear, consider a neighboring size or a seal with an offset lip. The selection depends on the speed, temperature and type of lubricant in the equipment.

If you need an equivalent or a close size, send us the part number 8660 together with the shaft, housing and height dimensions, and the equipment brand. A photo of the old seal or the housing drawing also works. At MR Accesorios Industriales we quote by WhatsApp and guide you to find the part that best suits your application, whether from the same DBH line or another compatible alternative.

DBH is an official brand that MR carries, and this seal joins the line of seals and oil seals we have available for industrial equipment. If your equipment has a leak or you are planning preventive maintenance, do not wait for the lip to fail completely: send the part number 8660 by WhatsApp and we will send you a quote with the alternatives that best fit your machine.
