The DBH 5025 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. With dimensions of 20 mm shaft diameter, 40 mm housing and 6 mm height, and an Lx design, it is press-fitted into the housing and runs against the shaft. It is a key part in pumps, electric motors, gearboxes and power transmission equipment, where it prevents leaks and protects the bearings. MR Accesorios Industriales supplies it as part of its line of seals and radial shaft seals.

This item is a radial shaft seal from the DBH brand, identified by part number 5025. Its dimensions are 20 mm shaft diameter (d), 40 mm housing diameter (D) and 6.00 mm height (h). The Lx design indicates a configuration with a sealing lip and spring, suitable for applications where the shaft rotates and a barrier against oil or grease is needed. The sealing lip, generally made of elastomer, rests on the shaft by means of a spring that ensures contact.

Typical applications for this seal include centrifugal pumps, electric motors, gearboxes, compressors and power transmission equipment. In all these cases, the seal prevents lubricant leakage and the entry of dust, water or particles, protecting the bearings and extending the service life of the assembly. It is also used on fan, mixer and conveyor shafts, where working conditions demand reliable, low-maintenance sealing.

To install a radial shaft seal correctly, check that the shaft and housing are clean, free of burrs and scratches. Lubricate the lip with the same oil or grease it will seal, and insert the seal perpendicularly using an installation tube or press that presses on the outer ring, never on the lip. Shaft and housing eccentricity must be minimal to avoid premature wear. If the shaft shows wear, consider a repair sleeve.
