The DBH 6767 radial shaft seal is a lip seal designed to close off the passage of oil, grease or contaminants on rotating shafts. Its size of 45 mm shaft diameter, 85 mm housing and 12 mm height makes it suitable for gearboxes, pumps and transmission equipment. MR Accesorios Industriales sells this brand and advises you so you choose the right seal for your application.

This item is a radial shaft seal from the DBH line, identified by code 6767. Its dimensions are 45.00 mm shaft diameter (d), 85.00 mm housing diameter (D) and 12.00 mm height (h). The Lx design corresponds to a single sealing lip with spring, designed to retain lubricant and exclude dust on rotating shafts. The lip elastomer runs on a ground sliding surface and the outer body is made of rigid material for a firm fit in the housing.

Seals of this size are used in gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. They also appear in agricultural machinery, packaging lines and hydraulic systems where oil leaks and the entry of particles must be prevented. If the equipment operates with high vibration or temperature, it is advisable to verify that the elastomer is suitable for those conditions.

To install a radial shaft seal, the shaft must be clean, free of burrs and have sufficient surface hardness so as not to wear the lip. The housing must be machined with the correct tolerance and free of marks. Lubricate the lip before inserting it and use an installation tube that presses on the outer diameter, never on the lip. If the shaft has a groove or wear, consider a seal with an offset lip or a repair sleeve.

To quote code 6767, send us the dimensions of your shaft and housing. At MR Accesorios Industriales we cross-reference the designation with the applicable options and confirm the option that best suits you. We can also quote seals with different elastomer qualities or with a double lip if your application requires it.

Before replacing a seal, check the condition of the shaft and housing: a new lip on a worn surface does not seal well. If you have doubts, write to us on WhatsApp with code 6767 and we will help you define the best solution for your equipment.
