The DBH 5085Sil oil seal is a single-lip radial seal that mounts on the shaft to retain oil or grease and keep out dust and water in gearboxes, pumps and electric motors. Its Lz design combines a sealing lip with a spring that maintains pressure on the shaft. With a 17 mm shaft diameter, 28 mm housing diameter and 7 mm height, it is a compact size for small and medium transmission equipment.

This DBH 5085Sil oil seal has a shaft diameter of 17 mm, a housing diameter of 28 mm and a height of 7.00 mm. The Lz design indicates that the sealing lip works with a steel spring that ensures continuous contact on the shaft, even with minor misalignment or vibration. The outer body is made of elastomer, suitable for machined metal housings with H8 tolerance or similar. It is a direct replacement part for equipment already using this standard size.

It is used in gearboxes, centrifugal pumps, electric motors, compressors and conveyor rollers. It also appears in machine tools and chain- or belt-drive equipment where lubricant must be contained and bearings protected from the environment. Due to its size, it is common in compact equipment: single-phase motors, worm gear reducers and low-power pumps. If the equipment operates with a lot of dust or water, it is advisable to verify that the lip and seal material are suitable for that exposure.

To install it, clean the housing and shaft, check for burrs or marks that could damage the lip, and lubricate the lip with the same grease or oil used in the equipment before inserting it. The seal is pressed in with a press or support tube, never by striking the lip. Shaft runout must not exceed the allowable values for radial shaft seals; if the shaft is worn in the contact area, consider a repair sleeve or an alternative size. Selection depends on speed, temperature and the fluid to be retained.
