The DBH 9820/85 is a single-lip radial shaft seal. It sits in a fixed housing bore and rides against a turning shaft, holding lubricant in and keeping dust, water and particles out. You will find seals of this type in gearboxes, pumps, electric motors and power transmission equipment. MR Industrial Accessories supplies this brand and helps you match the size you need.
Shaft 17 mm, housing 28.5 mm, height 7.00 mm: those three figures define the DBH 9820/85. The Lr designation means the lip carries a spring and is meant for rotating shafts that run with lubrication. Within the DBH line, the 9820/85 code points to this particular size. It is a direct replacement part for the moment the original seal hardens, loses its grip or comes out damaged during a teardown.
Seals built to these dimensions show up in gearboxes, centrifugal pumps, electric motors, compressors and conveyor rollers. Belt and chain drive equipment that has to keep oil or grease inside is another common home for them. In every case the seal works between a moving shaft and a stationary housing, and the contact surface needs lubrication so it does not wear out early.
Before pressing one in, confirm the shaft is clean and free of burrs, nicks or pull marks, and that the sealing surface has a suitable finish. Coat the lip with the same oil or grease the equipment runs on. The seal has to go in square to the housing bore, with no hammer blows that could distort the lip. On a shaft that already shows wear, a repair sleeve or an offset-lip seal is worth considering. Speed, temperature and the fluid being retained all shape the choice.
Looking for an equivalent? Send the number 9820/85 plus the shaft, housing and height figures. A photo of the old seal or the assembly drawing works too. With that information we look for an alternative in the DBH line or in the other brands we carry. The exact number is not essential; the dimensions and the application are enough to start the search.
