The DBH 9170/85 is a radial shaft seal built to keep lubricant in and contamination out where a shaft turns. Its dimensions are 25 mm at the shaft, 39.80 mm at the housing and 6.40 mm in height. The A 016 design points to a single lip with a spring. You will find this size in gearboxes, pumps, motors and transmission units. MR Industrial Accessories supplies this brand and can help you match the seal to your equipment.

The reference 9170/85 belongs to the DBH line of radial shaft seals. Reading the size: shaft 25 mm, housing 39.80 mm, width 6.40 mm. The lip runs against the rotating shaft while the outer case sits press-fitted in the bore, and the spring keeps the lip in contact. The A 016 design is a single-lip, spring-loaded geometry. In maintenance work this is a routine replacement item.

Seals of this size show up in gear reducers, centrifugal pumps, electric motors, compressors and belt or chain drives, as well as machine tools and agitators. The job is always the same: hold oil or grease inside and keep dust, water and particles outside, so bearings and gears are not worn out early. The seal costs little next to the parts it protects.

When choosing a replacement, check the shaft, bore and width against your equipment first. Surface speed, operating temperature and the lubricant in use all affect which lip compound and spring are suitable. At installation, coat the lip with the service oil or grease, seat the seal square to the shaft and press it in without hammering. A shaft with grooves or wear may call for a repair sleeve or a different size.
