The DBH 8502Pol seal is a single-lip radial shaft seal that mounts on the shaft and seals against the housing to retain lubricant and stop the ingress of dust, water or particles. With 70 mm shaft, 92 mm housing bore and 8.50 mm height, it is a commonly used size in gearboxes, pumps and transmission equipment. Its Lx-R design combines a sealing lip with a dust lip, which makes it suitable for environments with moderate dirt.

This item is a DBH radial shaft seal with the designation 8502Pol, with 70 mm shaft, 92 mm housing bore and 8.50 mm height. The Lx-R design indicates that the seal has a main sealing lip and an external lip for protection against contaminants. The elastomer runs on the rotating shaft and the outer diameter seats in the housing, creating the static seal. It is a wear part: when the lip hardens, tears or loses elasticity, it starts leaking oil along the shaft.

Typical applications for this size are in parallel-shaft gearboxes, centrifugal pumps, mixers, conveyors and chain or belt transmission equipment. It is also used in agricultural machinery and in process lines where oil or grease must be contained in a bearing. The dust lip adds value when the equipment works with dust, chips or mud, because it prevents the contaminant from reaching the main lip and shortening its service life.

To install it properly, check that the shaft has no burrs, scratches or wear in the contact area: a shaft with a deep groove will not seal even if the seal is new. Lubricate the lip before fitting it and place the seal square, without striking it directly on the elastomer. When selecting, take into account shaft speed, working temperature and the fluid to be retained. If the equipment has a lot of vibration or eccentricity, it is advisable to consider a design with greater rigidity.
