The DBH 5861 radial shaft seal is a lip seal that closes off the passage of oil or grease at the point where a shaft rotates inside a housing. Its function is to retain the lubricant inside and stop dust, water or particles that wear down bearings and bushings from getting in. It is used in gearboxes, pumps, electric motors and power transmission equipment, where the shaft passes through a housing and a reliable, low-maintenance barrier is needed.

This item is a radial shaft seal from the DBH brand, identified with part number 5861. According to the product page data, it works on a shaft with a diameter (d) of 30 mm, fits into a 50 mm bore (D) and has a height (h) of 12.00 mm. The indicated design is Lz, a lip configuration that defines how the seal seats on the shaft and how it behaves under pressure and in relation to the direction of rotation. These three dimensions are used to find the direct replacement.

Typical applications for a seal of this size appear in equipment with medium-section shafts: gearboxes, reducers, centrifugal pumps, electric motors, mixers and conveyors. In all these cases the seal separates the lubricant from the environment and protects the bearings from incoming contaminants. It is also found in machine tools and process equipment where lubricant cleanliness is key to the service life of the assembly.

To install it correctly, keep three points in mind. First, the condition of the shaft: a new lip on a scored or burred surface will not seal, so it is advisable to check the diameter and the finish. Second, the housing: it must be clean, free of impacts and with the diameter corresponding to the 50 mm on the product page. Third, the orientation of the lip according to the Lz design and the direction of rotation of the equipment. Lubricate the lip before inserting it and avoid striking it during installation.

If you need an equivalent or a nearby size, send us part number 5861 together with the shaft, housing and height dimensions you have on the equipment. With that data we can verify the match against the manufacturer's product page and offer you an alternative within the same radial shaft seal category. It also helps if you tell us the type of lubricant and the rotation speed, because they influence the choice of lip and material.
