The DBH 8103Pol radial shaft seal is a rotary shaft seal with a metal housing that prevents oil or grease leaks and blocks the entry of dust and water in gearboxes, pumps and transmission equipment. Its Mx design combines a main lip with a secondary exclusion lip, making it suitable for environments with moderate dirt. MR Accesorios Industriales supplies this official brand and advises you on choosing the correct size.

This DBH 8103Pol seal has a shaft diameter of 143.4 mm, a housing diameter of 170 mm and an overall height of 13.00 mm. The Mx design incorporates a main sealing lip and an external dust lip, mounted on a metal ring that fits by interference in the housing. The lip elastomer is formulated to resist mineral and synthetic oils, greases and water, with a temperature range that depends on the compound; consult the manufacturer's data sheet for specific conditions.

It is used in rotating equipment where lubricant must be retained and contaminants excluded: gearboxes, centrifugal pump bearings, mixers, screw conveyors and transmission shafts. It also appears in agricultural and road applications, where dust and mud require an additional exclusion lip. If the equipment operates with high vibration or misalignment, it is advisable to check the condition of the shaft and housing before replacing the seal.

To install it, clean the housing and shaft, verify there are no burrs or wear marks and lubricate the lip with the same oil or grease used in the equipment. Insert the seal perpendicular, without striking the elastomer, using a tube that bears on the outer ring. Selection depends on peripheral speed, temperature and fluid type; if the shaft shows wear, consider a repair sleeve or a nearby size. MR Accesorios Industriales can help you define the best option.
