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 power transmission equipment. MR Accesorios Industriales carries this official brand and advises you so you choose the right oil seal for your application.

This item is a radial shaft seal from the DBH line, identified with part number 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, intended 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.

Oil 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 a lot of 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 with sufficient surface hardness so it does not 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 shows a groove or wear, consider an oil seal with an offset lip or a repair sleeve.

If you need a nearby size or an equivalent from another brand, send us part number 6767 or the dimensions of your shaft and housing. At MR Accesorios Industriales we cross-reference the designation with the available alternatives and confirm the option that best suits you. We can also quote oil seals with different elastomer grades or with a double lip if your application requires it.

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