The DBH 1285 is a radial shaft seal built to keep oil or grease where it belongs and to block dust, water and other contaminants from reaching the bearing cavity. With a 47 mm shaft, a 69 mm housing bore and a 7.50/26 mm height, it fits gearboxes, pumps and motors where the available axial depth is tight. MR Industrial Accessories supplies this brand and helps you confirm the right seal for your equipment.

Reading the code matters when you reorder. The DBH 1285 designation points to a seal with a 47 mm shaft diameter, a 69 mm housing diameter and a 7.50/26 mm height. The A design is a single lip with a spring, so it holds lubricant on one side. The stepped height of 7.50/26 mm lets the seal sit in a housing with a shoulder or cover a deeper bore in assemblies where a plain seal would not reach. If your machine already runs this size, it drops in as a direct replacement.

You will find this seal in gearboxes, centrifugal pumps, electric motors, rollers and transmission shafts. In every case the job is the same: close the gap between the turning shaft and the fixed housing so lubricant stays in and dust or water stays out. It suits industrial equipment running at moderate speeds and at temperatures that standard elastomers handle.

Installation is where most seal failures start. Check the shaft for burrs or a worn track, and make sure the housing bore is clean and not deformed. Coat the lip with the same oil or grease used in the equipment, then press the seal in with a flat driver that pushes on the outer diameter only, never on the lip. If the shaft shows a groove, an offset lip or a repair sleeve is worth considering. Speed, temperature and the fluid being retained drive the final choice.

Need an equivalent? Send the full code stamped on the old part, or the exact shaft, housing and height measurements. With that we can search other brands or configurations in the same seals category. If your axial space is different or the A design does not match your setup, we can point you elsewhere. The more detail you send, the closer the match.
