The DBH 9642 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its designation 9642 corresponds to a seal with 65 mm shaft diameter, 85 mm housing diameter and a height of 8.00/3.80 mm, with Lz design. It is used in gearboxes, pumps, electric motors and transmission equipment to extend the life of bearings and gears. MR Accesorios Industriales sells this official brand and advises you to choose the right seal for your application.

The DBH 9642 is a single-lip radial shaft seal, identified by its numeric designation. Its main dimensions are 65 mm shaft diameter (d), 85 mm housing diameter (D) and a total height of 8.00 mm with a 3.80 mm profile in the lip area, according to the Lz design. This configuration allows it to be mounted in housings with a shoulder and ensures uniform contact on the shaft. The Lz design indicates a specific geometry of the lip and outer body, which favors oil retention and protection against dust and water.

Typical applications for this seal include gearboxes, speed reducers, centrifugal pumps, electric motors and power transmission equipment. In these systems, the seal prevents lubricant leaks and the ingress of abrasive particles that accelerate wear of bearings and gears. It is also used on fan, mixer and conveyor shafts, where sealing reliability is critical to maintain continuous operation and reduce maintenance costs.

To correctly select the seal, verify that the shaft and housing dimensions match those indicated: 65 mm and 85 mm respectively. The height 8.00/3.80 mm must be compatible with the housing depth and available space. The Lz design requires a housing with a shoulder for firm seating. During assembly, lubricate the lip with the same oil as the equipment, avoid impacts and make sure the shaft has no burrs or splines that could damage the seal. Careful installation extends the service life of the seal.
