With dimensions of 25.50 mm shaft diameter, 40.00 mm housing diameter and 6.50 mm height, it is press-fitted into the housing and runs against the shaft. It is a key component in gearboxes, pumps, electric motors and power transmission equipment, where it prevents leaks and protects bearings. MR Accesorios Industriales supplies this brand so you can handle your replacement with confidence.

This DBH 6642 oil seal has an Lz design, with a sealing lip and spring that ensures uniform contact on the shaft. Its dimensions are 25.50 mm shaft diameter (d), 40.00 mm housing diameter (D) and 6.50 mm height (h). The lip elastomer is formulated to resist mineral oils and greases, and the metal case ensures a firm fit in the housing. It is a standard solution for rotating shafts that require sealing.

Typical applications for this oil seal include gearboxes, centrifugal pumps, electric motors, compressors and power transmission equipment. In all these cases, the seal prevents lubricant leakage and the ingress of dust or water, extending the service life of bearings and gears. It is also used in machine tools and agricultural equipment, where environmental contamination is demanding.

To install the seal correctly, verify that the shaft has adequate surface hardness and a fine surface finish, and that the housing is clean and free of burrs. Lubricate the lip before inserting it and use an installation tool that presses on the outer diameter, never on the lip. Selection must consider the shaft surface speed, operating temperature and the type of fluid to be retained. If you have any questions, ask us.
