The DBH 6890 radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the entry of dust, water or contaminating particles. With dimensions of 42 mm shaft diameter, 65 mm housing diameter and 14 mm height, and an A 025 design, it is used in gearboxes, pumps, electric motors and power transmission equipment. MR Accesorios Industriales carries this official brand and advises you so you choose the correct seal for your application.

This item is a radial shaft seal from the DBH brand, identified by the code 6890. Its dimensions are 42 mm shaft diameter (d), 65 mm housing diameter (D) and 14.00 mm height (h). The A 025 design corresponds to a single-lipped seal with spring, suitable for rotating shafts with lubrication. The sealing lip, generally made of elastomer, runs on the shaft and keeps the lubricant inside, while the outer body fits into the housing to ensure sealing.

Typical applications of this seal include gearboxes, reducers, centrifugal pumps, electric motors, compressors and power transmission equipment. In all these cases, the seal protects bearings and gears from external contamination and prevents oil or grease leaks. It is a wear part that should be replaced when lubricant leaks, abnormal noises or vibrations are detected in the seal area.

For installation, verify 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 enter perpendicular to the shaft, without direct blows on the lip; use a tube or socket of suitable diameter that rests on the outer ring. If the shaft shows wear, consider a neighboring size or a seal with an offset lip. The selection depends on speed, temperature and type of lubricant.
