The DBH 9307 radial shaft seal is a lip seal that blocks the passage of oil or grease at the point where a shaft passes through a housing. It is used in gearboxes, pumps, electric motors and power transmission equipment to retain lubricant and stop dust or water from entering. Its designation 9307 corresponds to a seal for an 18 mm shaft, 40 mm housing and 7 mm height, with Lx design.

The DBH 9307 is a single-lip radial shaft seal. According to the product page data, it runs on a shaft of 18 mm diameter, fits into a 40 mm housing and has a height of 7.00 mm. The Lx design indicates that the lip is rubber and does not have a metal spring, so it is used in applications where fluid pressure is low and shaft speed is moderate. DBH is a brand MR sells.

This type of seal appears in gearboxes, centrifugal pumps, electric motors, rollers and power transmission equipment. It is also mounted on fan, mixer and conveyor shafts, where oil must be prevented from escaping and dust from entering the bearings. At these points, the seal works alongside the bearing and defines a good part of the assembly's service life.

To choose the right seal, check that the shaft and housing diameters match the values on the product page. The shaft surface must be ground and free of burrs; the housing must be clean and free of deformation. Before mounting, lubricate the lip with the same grease or oil used in the equipment. If the shaft has play or wear, the lip does not seat properly and leakage appears within a few hours of operation.
