The DBH 9557 radial shaft seal is a radial seal of A 135 design that is fitted between a rotating shaft and a fixed housing to retain lubricant and exclude contaminants. Its dimensions —50 mm shaft, 116 mm housing and a height of 13/17 mm— make it suitable for equipment with medium-section shafts and sealing chambers of a certain depth. MR Accesorios Industriales carries this brand and advises you so you can choose the correct radial shaft seal for your application.

This item is a DBH 9557 radial shaft seal, identified by its numeric designation. According to the product page data, it runs on a shaft of 50 mm diameter (d), seats in a bore of 116 mm (D) and has a total height that varies between 13.00 and 17.00 mm (h). The A 135 design corresponds to a configuration with a sealing lip and reinforced body, designed to retain oil or grease under continuous rotation conditions. The DBH brand is a brand that MR carries, so you can ask us and we will quote you.

Typical applications for a radial shaft seal of this size include gearboxes, centrifugal pumps, conveyor rollers, mixers and power transmission equipment in general. In all cases, the radial shaft seal performs two functions: preventing lubricant from leaking outward and blocking the entry of dust, water or particles that accelerate the wear of bearings and gears. Due to its housing diameter, it is usually found in medium-sized industrial equipment, where radial space is not critical but reliable sealing is required.

To install a radial shaft seal such as the 9557, check that the shaft has no burrs or deep marks in the contact area and that the housing is clean and free of deformation. Lubricate the lip with the same grease or oil as the equipment before inserting it, and strike evenly on the outer ring, never on the lip. The 13/17 mm height indicates that the radial shaft seal can seat in chambers of different depths within that range; respect the exact housing dimension to prevent it from being exposed or forced.

If you need a radial shaft seal equivalent to the 9557 or a nearby size, the most practical thing is to send us the full code, a photo of the part and the dimensions taken with a caliper: shaft diameter, housing diameter and height. With that data we can look for an alternative within the same brand or from another company we carry, always respecting the tolerances and the lip type. We can also guide you if the A 135 design is not suitable for your application and another geometry should be evaluated.
