The DBH 6858Vit 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 30 mm shaft diameter, 42 mm housing diameter and 7 mm height, and an A 156-R H design, it is a common replacement part in industrial equipment. MR Accesorios Industriales carries this brand and advises you so you choose the right seal.

This item is a radial shaft seal from the DBH brand, identified with the code 6858Vit. Its standardized dimensions are: shaft diameter (d) of 30 mm, housing diameter (D) of 42 mm and height (h) of 7.00 mm. The A 156-R H design indicates a specific construction configuration within the DBH seal line. It is intended to be press-fitted into the housing and seal against a rotating shaft, with the lip in direct contact with the shaft surface.

Typical applications of a seal such as the 6858Vit include gearboxes, pumps, electric motors, conveyor rollers and power transmission equipment. In all these cases, the seal serves the dual function of containing the oil or grease and blocking the entry of external contaminants. It is a wear part that should be replaced when leaks appear or when the lip shows hardening, cuts or loss of elasticity.

To correctly select this seal, verify that the shaft and housing dimensions match those of the equipment. The shaft surface must be in good condition, without grooves or pronounced wear, and the housing must be clean and free of burrs. During assembly, lubricate the lip with the same service oil or grease, insert the seal perpendicularly and avoid striking it directly on the lip. If the shaft shows a worn track, consider using a wear sleeve.
