The DBH 8834 radial shaft seal is a lip seal designed to keep lubricant in and contaminants out of equipment with large-diameter shafts. It fits a 280 mm shaft and seats in a 320 mm bore, with a height of 20 mm. Its Lz design incorporates an auxiliary lip that improves sealing under moderate dirt conditions. It is a common replacement part in gearboxes, mills and process pumps.

This item is a radial shaft seal from the DBH brand, identified by code 8834. According to the product page data, it is intended for a shaft with a 280 mm diameter, a 320 mm housing and a total height of 20.00 mm. The Lz design corresponds to a seal with a main sealing lip and a secondary exclusion lip, which helps retain grease or oil and blocks dust. The manufacturer's commercial designation is 8834 and is used as a reference to order the replacement.

Typical applications for a seal of this size include large gearboxes, ball or rod mills, process centrifugal pumps, industrial mixers and mining or cement equipment. In all these cases, the seal's function is to retain lubricant inside the assembly and prevent it from escaping along the shaft, as well as to prevent the entry of particles that accelerate wear on bearings and gears.

To install a radial shaft seal, check that the shaft has no burrs or deep marks in the sealing area, and that the housing is clean and free of deformation. The shaft surface must have suitable hardness and roughness for the lip; if it is heavily worn, it may require a repair sleeve. During installation, lubricate the lip with the same oil or grease used in the equipment and avoid striking it or reversing its position. The 20 mm height must match the depth of the bore.
