The DBH 6780 oil seal is a single-lip radial shaft seal with a spring, designed for 15.87 mm rotating shafts and 25.40 mm housings. Its 4.75 mm height and Lz design make it suitable for tight spaces where lubricant must be retained and contaminants excluded. It is used in pumps, electric motors, gearboxes and power transmission equipment operating at moderate speeds. MR Accesorios Industriales supplies this official brand and advises you so you can choose the right seal for your application.

This item is a DBH 6780 radial shaft seal, identified by its designation 6780. Its dimensions are: shaft diameter 15.87 mm, housing diameter 25.40 mm and height 4.75 mm. The Lz design corresponds to a spring-loaded sealing lip, intended for rotating shafts. The DBH brand is an official brand supplied by MR, so the product arrives with its corresponding identification and traceability.

Typical applications for a seal of this size include small centrifugal pumps, low-power electric motors, speed reducers, compressors and belt- or chain-driven transmission equipment. In all cases, its function is to retain oil or grease inside the assembly and prevent the entry of dust, water or particles. It is a wear part that should be replaced when leaks appear or the bearing becomes noisy.

To install the seal correctly, check that the shaft and housing are clean, free of burrs and scratches. Lubricate the lip with the same oil or grease used in the application before inserting it. The seal must sit perpendicular to the shaft and fully seated in the housing. If the shaft shows wear, consider using a nearby size or a repair sleeve. Selection depends on speed, temperature and lubricant type.
