The DBH 8502Pol oil seal is a single-lip radial shaft seal that mounts on the shaft and seals against the housing to retain lubricant and block the entry of dust, water or particles. With a 70 mm shaft, 92 mm housing and 8.50 mm height, it is a common size in gearboxes, pumps and power transmission equipment. Its Lx-R design combines a sealing lip with a dust lip, making it suitable for environments with moderate contamination.

This item is a DBH radial shaft seal with the designation 8502Pol, with a 70 mm shaft, 92 mm housing 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 to leak oil along the shaft.

Typical applications for this size are parallel-shaft gearboxes, centrifugal pumps, mixers, conveyors and chain or belt drive 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 operates with dust, chips or mud, because it prevents the contaminant from reaching the main lip and shortening its service life.

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