The DBH 9307 radial shaft seal is a lip seal that closes off 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 with 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 7.00 mm height. 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. The DBH brand is an official brand that MR carries.

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 those points, the seal works alongside the bearing and defines a good part of the assembly's service life.

To choose the right seal, verify 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, 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.

If you need a nearby size or an equivalent from another brand, send us the part number 9307 together with the shaft, housing and height dimensions. With that data we look for the available alternative in the seal and oil seal line. We can also advise you if the Lx design is not suitable for your application and a seal with a spring or double lip is needed.
