The DBH 9665Pol radial shaft seal is a lip seal that mounts on a 38 mm shaft and seals against a 74 mm housing, with a 9 mm height. Its function is to retain lubricant inside the assembly and block the entry of dust, water or particles that accelerate wear on bearings and bushings. It is used in gearboxes, pumps, electric motors and power transmission equipment operating with rotating shafts. MR Accesorios Industriales carries this brand as part of its seals line.

This item is a lip seal with the following dimensions: shaft diameter 38 mm, housing diameter 74 mm and height 9.00 mm. It corresponds to the A 274-R design, a single-lip configuration with a spring that ensures continuous contact on the shaft. The outer body is metal and the lip is elastomer, which allows it to be press-fitted into the housing without auxiliary retainers. It is a standard replacement part within the radial seals category.

Typical applications for a seal of these dimensions appear in equipment with transmission shafts: speed reducers, centrifugal pumps, electric motors, mixers and conveyors. It is also found in agricultural and industrial machinery where bearings must be protected from the environment. In all cases it works on a rotating shaft and against a fixed housing, separating two zones: the lubricated one and the exposed one.

To correctly select a seal, you must verify the shaft diameter, the housing diameter and the available height. The shaft surface must be ground and free of burrs; a mark or wear on the running surface accelerates lip failure. During installation, lubricate the lip with the same grease or oil used in the equipment and press perpendicular to the housing, without striking the elastomer. If the shaft shows wear, consider a neighboring size or a repair sleeve.

If you need an equivalent or a different size, the most practical approach is to send us the code engraved on the old seal or the three dimensions: shaft, housing and height. With that data we can look for the closest size within the same series or from another brand we carry. We can also advise you if the A 274-R design is not suitable for your application and a different lip type or material is a better fit.
