The DBH 9012 is a radial shaft seal built to keep lubricant where it belongs and to shut out dust, water and other contaminants at the point where a rotating shaft leaves its housing. Equipment running 150 mm shafts, such as gearboxes, pumps, motors and transmission drives, is where this size shows up most often. MR Industrial Accessories supplies this line and will confirm the dimensions with you before a quote goes out.

The number 9012 is the designation for this seal. Three measurements govern the fit: shaft 150 mm, housing 170 mm, height 12.00 mm. The design shown is Lx, a single lip with a metal case. Nothing here is made to order; the part is picked from those three values plus the demands of the service it will see.

Seals of this size usually sit on heavy transmission shafts. Think reducers, centrifugal and positive displacement pumps, electric motors, and the rollers or wheel hubs of road and farm machinery. In each of those spots the job is the same: hold oil or grease on the inside and keep outside contamination from getting in.

Before pressing one in, look over the shaft. Burrs, scratches or a worn contact band will shorten the seal's usefulness. The bore should be clean and free of dents. Coat the lip with lubricant, then seat the seal square to the shaft rather than at an angle. Where the shaft already shows a clear wear groove, a seal with the lip set in a different position or a wear sleeve is worth considering. Speed, temperature and the fluid being sealed also belong in the selection, and those details should be checked against the manufacturer's data sheet.

Need the same seal in another brand or with a different height? Send us the code 9012 together with your shaft, housing and height figures. From there we look through the lines we carry for a match. We can also tell you whether the Lx design suits your equipment or if a different lip style would serve the application better.
