The DBH 5374 oil seal is a radial lip seal designed to close off the passage of lubricant and stop the entry of dust, water or particles in equipment with a rotating shaft. With 65 mm shaft, 85 mm housing and 12 mm height, it is mounted in gearboxes, pumps, motors and transmissions where oil or grease must stay inside. MR Accesorios Industriales carries this official brand and helps you confirm the size before quoting.

This item is a DBH radial shaft seal with designation 5374. Its attributes are specific: shaft diameter (d) of 65 mm, housing diameter (D) of 85 mm and height (h) of 12.00 mm. The indicated design is Lz, which corresponds to a sealing lip with a single-lip geometry and outer metal reinforcement. It is a compact-section seal, suitable for standard housings and shafts with a careful surface finish.

Typical applications for a seal of this size appear in gearboxes, centrifugal pumps, electric motors, rollers and power transmission equipment. In all those cases the seal performs the same function: retaining the lubricant inside the assembly and preventing contaminants from entering from outside. It is also used as a secondary closure in bearing housings and bushings where there is continuous rotary motion.

To install it properly, check that the shaft has the right size and finish, and that the housing is clean and free of burrs. The lip must be lubricated before inserting the shaft, and it is advisable to use an installation tube that presses on the outer diameter, never on the lip. If the equipment operates with heavy vibration or temperature, check the hardness of the elastomer and the type of spring before choosing the replacement.

If you need an equivalent or a nearby size, send us part number 5374 along with the shaft, housing and height dimensions. With that data we cross-reference the DBH series and offer compatible alternatives. We can also review the Lz design and suggest lip or material variants according to the fluid and the working conditions of your equipment.
