This item is a DBH radial shaft seal, identified with the designation 1283. Its dimensions are 43.00 mm shaft diameter (d), 53.00 mm housing diameter (D) and 8.00 mm height (h). The Ms design indicates a specific construction configuration from the manufacturer, which in this case corresponds to a single-lip seal with a spring. It is a precision part that is press-fitted into the housing and seals against the rotating shaft. DBH is an official brand that MR carries, so you can ask us about its applications.

Radial shaft seals such as the DBH 1283 are used in gearboxes, pumps, electric motors, reducers and transmission shafts. Their main function is to prevent oil or grease leaks and to protect bearings and internal mechanisms from dust, water and particles. They are common in industrial equipment, agricultural machinery and vehicles. Correct seal selection ensures long-lasting sealing and reduces maintenance. If you need to replace a seal in a piece of equipment, this model may be the right one if the dimensions match.

To install a radial shaft seal, check that the shaft and housing are clean and free of burrs. Lubricate the lip with the same oil or grease used in the equipment before installation. Insert the seal perpendicularly, using a tube or socket that presses on the outer diameter, never on the lip. Make sure the spring is correctly positioned. Peripheral speed, temperature and pressure are critical factors; consult the manufacturer's specifications for each application. Careful installation extends the service life of the seal.
