The DBH 8891 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions of 45.00 mm shaft diameter, 55.00 mm housing diameter and 7.00 mm height make it suitable for equipment where axial space is limited. MR Accesorios Industriales carries this 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 part number 8891. According to the product page data, it has a shaft diameter (d) of 45 mm, a housing diameter (D) of 55 mm and a height (h) of 7.00 mm. The Lx design corresponds to a configuration with sealing lip and spring, intended for rotating shafts. It is a standard replacement part for press-fitting into a machined cavity.

It is used in gearboxes, pumps, electric motors, transmission shafts and industrial equipment in general. Its function is twofold: it prevents oil or grease from leaking out and blocks the entry of dust, water or particles. It is commonly found in applications where the shaft rotates at moderate speeds and a reliable barrier between the lubricant and the environment is required.

To correctly select a seal, verify that the shaft, housing and height dimensions match those of the existing housing. The shaft surface must be ground and free of splines to avoid damaging the lip. When installing, lubricate the lip with the same oil used in the equipment and use a support tube to avoid deforming the seal. If the shaft is worn, consider a neighboring size or a seal with an auxiliary lip.
