The DBH 5175Sil seal is a radial shaft seal of 40.00 mm shaft, 55.00 mm housing and 8.00 mm height, with Lx design. It is used to retain lubricant and exclude contaminants on rotating shafts, inside gearboxes, pumps, electric motors and transmission equipment. Its flexible lip runs on the shaft and maintains sealing under continuous rotation conditions. MR Accesorios Industriales carries this brand and advises you on choosing the correct seal for your application.

This item is a DBH radial shaft seal, designation 5175Sil, with dimensions of 40.00 mm on the shaft (d), 55.00 mm on the housing (D) and 8.00 mm height (h). The Lx design corresponds to a configuration with a sealing lip and metal body, suitable for rotating shafts. The lip elastomer and the metal body combine to withstand continuous friction and maintain sealing. It is a standard replacement part within the seals and oil seals category.

Typical applications include gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. In all cases, the seal prevents oil or grease leaks and blocks the ingress of dust, water or particles. It is also used in machine tools and agricultural equipment, where the shaft rotates at moderate speeds and environmental contamination is a critical factor for bearing service life.

To install a radial shaft seal, verify that the shaft measures 40.00 mm and the housing 55.00 mm, with no burrs or marks. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, with the lip face toward the side to be sealed. The 8.00 mm height must match the housing depth. If the shaft shows wear, evaluate a nearby size or a repair sleeve. Selection depends on speed, temperature and the fluid to be retained.
