The DBH 6690Vit radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the ingress of dust, water or contaminating particles. With dimensions of 30 mm shaft diameter, 42 mm housing diameter and 7 mm height, and an Lz-R design, it is a common replacement part in pumps, electric motors, gearboxes and transmission equipment. MR Accesorios Industriales supplies this brand as part of its seals and oil seals line.

This DBH 6690Vit oil seal has a designation that corresponds to its dimensions: 30 mm shaft diameter (d), 42 mm housing diameter (D) and 7 mm height (h). The Lz-R design indicates a configuration with a sealing lip and a spring that ensures continuous contact on the shaft. It is designed to be press-fitted into the housing and seal against a rotating shaft, with the lip facing the fluid to be retained.

Typical applications for this oil seal include centrifugal pumps, electric motors, speed reducers, gearboxes and power transmission equipment. It is also used in agricultural machinery, process equipment and hydraulic systems where oil or grease must be contained and bearings protected from the environment. Its size of 30 x 42 x 7 mm is common on 30 mm diameter shafts with standard housings.

To correctly select an oil seal, verify that the shaft, housing and height dimensions match those of your equipment's housing and shaft. The Lz-R design is suitable for shafts with moderate speeds and normal lubrication conditions. During assembly, make sure the lip is not damaged, lubricate the lip with the same oil or grease used in the system and verify that the spring is correctly positioned. Shaft eccentricity and surface finish affect the service life of the seal.
