A radial shaft seal from DBH, the 9745/85 keeps lubricant where it belongs and keeps dust, water and other contaminants out of assemblies built around a rotating shaft. It fits a 28 mm shaft, a 40 mm housing bore and an 8.00 mm height, and it carries the A 156 design. MR Industrial Accessories supplies it within its seals and oil seals line.

The code on this part tells you most of what you need. The 9745/85 designation identifies the seal, while the three figures that matter at the bench are shaft 28 mm, housing 40 mm and height 8.00 mm. The A 156 design refers to a defined construction from the manufacturer: lip profile, metal case and retaining spring. Because the lip rides directly on the shaft, all three dimensions have to line up with the machine before you order.

Seals in this size range turn up in gearboxes and speed reducers, centrifugal pumps, electric motors, compressors and power transmission equipment. In each case the job is the same: hold oil or grease inside the housing and keep outside contamination away from bearings and gears. Fan shafts, mixer shafts and conveyor shafts also use this type of seal, where steady rotation calls for dependable sealing with low friction.

Installation decides how long a seal lasts. Inspect the shaft first and remove any burrs, scratches or worn spots in the contact zone. Coat the lip with the same lubricant the equipment runs on, then drive the seal in with a tube that presses on the outer diameter only, never on the lip. Keep it square to the shaft; even a slight tilt leads to leaks. If the shaft shows a worn track, a repair sleeve is one option, and our team can review the case with you.
