The DBH 1089 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants in rotating equipment. It is installed in cylindrical housings and works on rotating shafts, where the flexible lip maintains dynamic contact. It is a key part for protecting bearings, bushings and gears in environments with dust, water or chips. MR Accesorios Industriales supplies this official brand and advises you so you can choose the right seal according to the conditions of your equipment.

This item is a DBH 1089 radial shaft seal, identified by its numerical designation. Its main dimensions are: shaft diameter 71.42 mm, housing diameter 98.45 mm and height 11.91 mm. Design A 206 corresponds to a single-lip configuration with spring, suitable for general sealing applications. Made of elastomer resistant to oils and greases, this seal guarantees tightness on rotating shafts. It is important to verify that the dimensions match the housing and the shaft before mounting it.

Typical applications of this seal include gearboxes, pumps, electric motors, conveyor rollers and power transmission equipment. In the food, chemical or process industries, where there is exposure to lubricants and external agents, the seal prevents leaks and the entry of particles. It is also used in agricultural and road machinery, where dust and moisture demand reliable sealing. Its compact size makes it suitable for tight spaces with shafts of a diameter close to 71 mm.

To select this seal correctly, take into account the rotation speed, the operating temperature and the type of lubricant. Design A 206 with a single lip is appropriate for moderate speeds and low pressures. When mounting it, lubricate the lip with the same oil used in the equipment, insert it perpendicular to the shaft and avoid damaging the sealing edge. Verify that the housing is clean and free of burrs. If the shaft shows wear, consider using a wear sleeve or a seal with an auxiliary lip.
