Part 9499 from the DBH line is a radial shaft seal, the kind of lip seal that keeps oil or grease inside a rotating assembly. Its Mx construction pairs a spring-loaded sealing lip with a metal outer case that presses into the housing bore. With a 33 mm shaft, a 44 mm housing and an 8 mm height, it fits gearboxes, pumps and small to medium electric motors. MR Industrial Accessories supplies this brand and can verify the size or suggest an equivalent before you order.

Reading the code is straightforward: 9499 identifies the item, and the three measurements define the fit. Shaft 33 mm, housing 44 mm, height 8.00 mm, Mx design. In the Mx style the lip carries a spring and rides on the shaft with light interference while the metal case holds the seal in the bore. Before replacing a seal, measure the old one or the shaft and bore it came out of, and compare all three figures.

Seals in this size range show up at the point where a shaft leaves a crankcase or bearing housing: gear reducers, centrifugal pumps, electric motors, rollers and other power transmission equipment. Machine tools and process lines use them too, wherever lubricant has to stay in and dirt has to stay out. In dirty or wet conditions, a version with a second lip or a dust guard is worth considering.

Installation decides how long a seal lasts. Inspect the shaft first: no burrs, no scratches, no wear track under the lip. Polish and lubricate the contact surface, and make sure the bore is clean and round. Drive the seal in squarely with a tube or proper driver, and never strike the lip. A shaft with a deep groove may call for an oversized repair size or a wear sleeve.

For an equivalent, send code 9499 or simply the old seal's shaft, housing and height figures. If the Mx design does not suit the application, we can point you toward another lip type or material. Details such as temperature, speed and the lubricant in use help narrow the choice.
