The DBH 9168/85 is a radial shaft seal from the DBH line, identified by the designation 9168/85 and the A 016 design. It measures 25 mm at the shaft, 39.70 mm at the housing and 8.00 mm in height, and is press-fitted into crankcases, covers and housings to keep lubricant in and contaminants out. As a wear part, it should be replaced when oil loss or dust ingress appears. MR supplies this brand and can help you confirm the right seal for your equipment.

This seal is a single lip, spring-loaded radial shaft seal intended for rotating shafts where oil or grease must be retained and dirt excluded. The A 016 design refers to the lip geometry and case style. Before installation, verify all three dimensions—shaft 25 mm, housing 39.70 mm, height 8.00 mm—against the shaft and housing, since even small differences prevent a proper fit.

Seals of this size are commonly found in gearboxes, pumps, electric motors, compressors, machine tools and transmission equipment, typically on 25 mm shafts running at moderate speeds with liquid or semi-solid lubricant. They also appear in agricultural, road and material handling equipment, where dust and water demand reliable sealing. If the equipment operates with significant vibration or misalignment, inspect the shaft and housing condition before replacing the seal.

Correct selection goes beyond dimensions. The seal must fit with an interference fit in the housing, and its lip must run on a ground surface free of grooves. Peripheral speed, temperature and lubricant type determine the lip material, so dimensions alone are not enough. During installation, lubricate the lip, use a support tube to avoid deformation, and make sure the spring faces the fluid side. If the shaft is worn, consider a repair sleeve or a seal with the lip in a different position.

For an equivalent, send the 9168/85 part number along with the shaft, housing and height dimensions, and a photo of the old seal if possible. Also indicate the equipment where it is installed and the lubricant used. With that information, we can look for alternatives within the same category or from other brands we supply, confirming that the lip geometry and material are compatible with your application.
