The DBH 8790 radial shaft seal is a lip seal designed to block the passage of oil or grease on rotating shafts, housed in a 70 mm bore. Its A 158 design and dimensions of 55 x 70 x 12.30 mm make it suitable for equipment with 55 mm shafts where lubricant must be contained and dust or water ingress prevented. MR Accesorios Industriales supplies this brand and advises you on choosing the correct seal for your application.

This DBH 8790 oil seal has a shaft diameter of 55 mm, a housing bore of 70 mm and a height of 12.30 mm. The A 158 design corresponds to a single-lip configuration with spring, intended to retain lubricant in one direction and exclude environmental contaminants. The 8790 designation identifies the exact size within the DBH line, so when requesting a replacement it is advisable to verify these three values before requesting a quote.

Radial shaft seals such as the DBH 8790 are used in gearboxes, pumps, electric motors, transmission shafts and process equipment. Their function is to keep lubricant inside the assembly and prevent particles from entering that would accelerate wear on bearings and gears. They are also used in applications with low pressure and continuous rotary motion, provided that speed and temperature are compatible with the lip material.

To install this seal, verify that the shaft measures 55 mm and has a surface free of burrs or marks; the 70 mm housing must be clean and free of deformation. Lubricate the lip before inserting it and place the seal perpendicular to the shaft to avoid damaging the spring. If the equipment operates with high vibration or misalignment, consider a more rigid design or consult MR to select the appropriate variant.
