The DBH 9989 is a radial shaft seal built for rotating shaft applications. It keeps lubricant where it belongs, inside the housing, and blocks outside contaminants such as dust and water from reaching bearings and gears. Its envelope is compact: shaft 17.45 mm, housing 28.50 mm, width 7.00 mm. For plants running small motors, pumps and similar equipment, this is a routine replacement item worth keeping on the maintenance list.

The 9989 code identifies an Lr style seal, meaning a single lip with a spring. The spring keeps the lip in contact with the shaft, so oil or grease stays in and particles stay out. Dimensional data to match against your equipment: shaft seat d 17.45 mm, housing bore D 28.50 mm, overall height h 7.00 mm. The shaft seat is the nominal figure the lip runs on, while the 28.50 mm bore is where the outer diameter seats.

You will find seals of this type in electric motors, pumps, gear reducers, transmission boxes, conveyor rollers and farm machinery. Their job is simple but important: hold the lubricant in place and keep grit away from bearings and gears. When a seal starts weeping or lets contamination through, wear on the surrounding parts speeds up, which is why seals are checked and swapped during planned maintenance.

Choosing the right seal comes down to two things. First, confirm the shaft and housing measurements, since a few hundredths of a millimeter matter at this size. Second, review how the machine runs: speed, temperature and the lubricant in use. The Lr configuration suits moderate speeds and low pressure. At installation, coat the lip with lubricant, use a tool that will not cut or roll the lip, and press the seal in square to the shaft. A seal fitted at an angle or driven in dry tends to leak early.
