The DBH 8228 oil seal is a single-lip radial shaft seal designed for rotating shafts with a 30 mm diameter. Its main function is to retain lubricant inside the housing and prevent the entry of external contaminants such as dust or water. It is used in a wide variety of industrial equipment, from electric motors to pumps and gearboxes. With a 40 mm housing and a 7 mm height, this oil seal provides reliable sealing under continuous operating conditions.

The DBH 8228 is a radial shaft seal with an Lx design, which indicates that it has a sealing lip and a stainless steel spring that ensures constant pressure on the shaft. Its dimensions are 30.00 mm shaft diameter (d), 40.00 mm housing diameter (D) and 7.00 mm height (h). This combination is common in applications where axial space is limited and effective sealing against oil or grease leaks is required.

Typical applications for this oil seal include electric motors, centrifugal pumps, speed reducers, gearboxes and conveyor rollers. In all these cases, the DBH 8228 oil seal protects the bearings and internal components from the entry of particles, extending the service life of the equipment. It is important to select the right oil seal according to temperature, speed and lubricant type conditions.

For correct installation, verify that the shaft and housing are clean and free of burrs. Lubricate the seal lip with the same oil or grease that the equipment will use before inserting it. Installation should be done with a press or suitable tool, applying uniform force on the outer diameter. Avoid striking the oil seal, as this could damage the lip and cause premature leaks.
