The DBH 9281 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions — 136.8 mm shaft diameter, 165 mm housing diameter and 13 mm height — make it suitable for equipment with large-diameter shafts, such as gearboxes, pumps and heavy machinery. MR Accesorios Industriales sells this official brand and advises you so you can choose the right seal for your application.

This item is a DBH radial shaft seal, designation 9281, with the following dimensions: shaft diameter (d) 136.8 mm, housing diameter (D) 165 mm and height (h) 13.00 mm. Design A 168 corresponds to a specific construction configuration from the manufacturer. It is a lip seal with a metal case and an elastomeric element, designed to be press-fitted into a housing and seal against a rotating shaft. These dimensions allow it to be identified unambiguously when replacing a worn seal.

Typical applications for a seal of this size include gearboxes, centrifugal pumps, mills, mixers and power transmission equipment in general. In all cases, the function is twofold: preventing oil or grease from leaking out and blocking the entry of dust, water or particles that accelerate wear on bearings and gears. Because of its shaft diameter, it is usually found in industrial-scale machines rather than light equipment.

To correctly select a seal you must verify not only the three main dimensions, but also the type of elastomer, the working temperature range and the permissible peripheral speed. Mounting requires cleaning the housing, lubricating the lip and using a tool that prevents damage to the sealing edge. Installation with the lip inverted or struck causes premature leaks even if the dimensions are correct. If you have doubts, consult us before fitting the seal.

If you need an equivalent or a nearby size, the most practical approach is to send us the code engraved on the old seal, a photo of the part and the dimensions measured with a caliper. With that data we can look for alternatives within the same brand or others we sell. We can also advise you if the housing is worn and it is worth evaluating a repair or a seal with a greater height.
