The DBH 9221 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants in rotating equipment. Its A 128 design and its dimensions of 35 mm shaft, 54.90 mm housing and 9.00/14.70 mm height make it suitable for assemblies where axial space is limited and a firm contact lip is required. It is used in pumps, electric motors, gearboxes and transmissions, among other industrial applications.

This DBH 9221 oil seal has a shaft diameter of 35 mm, a housing diameter of 54.90 mm and a height of 9.00/14.70 mm. The A 128 design corresponds to a single-lip configuration with spring, intended for rotating shafts at moderate peripheral speeds. The stepped height allows it to be seated in cavities with a shoulder or in covers that require a deeper seat. It is a replacement part for equipment operating with oil or grease that needs to contain the lubricant inside the assembly.

Typical applications include centrifugal pumps, electric motors, speed reducers, transmission shafts and continuous process equipment. In these assemblies, the seal prevents oil leaks and the entry of dust, water or particles that accelerate wear on bearings and gears. It is also used in agricultural and industrial machinery where cleanliness of the environment is not guaranteed and an effective barrier against external contamination is required.

To select this seal correctly, check that the shaft diameter is 35 mm and that the housing has a diameter of 54.90 mm. The 9.00/14.70 mm height must match the depth of the cavity. During installation, lubricate the lip with the same oil or grease used in the equipment, avoid damaging the sealing edge and make sure the spring is correctly seated. If the shaft shows wear or roughness, consider a repair or a seal with an auxiliary lip.
