The DBH 9423 radial shaft seal is a lip seal designed to mount on rotating shafts and prevent oil or grease leaks while blocking the entry of dust and contaminants. Due to its dimensions of 50 mm inner diameter, 68 mm outer diameter and 8 mm height, it is used in gearboxes, pumps, electric motors and transmission equipment. MR Accesorios Industriales carries this official brand and advises you so you choose the right seal for your application.

This item is a DBH 9423 radial shaft seal with the following dimensions: 50 mm shaft diameter, 68 mm housing diameter and 8 mm height. Its Lx design indicates a configuration with a sealing lip and metal case, suitable for retaining lubricant on rotating shafts. The lip is made of an elastomer resistant to wear and mineral oils, while the outer case provides a firm fit in the housing. It is a key part for maintaining sealing in equipment where continuous rotation demands reliable sealing.

Typical applications for this seal include gearboxes, speed reducers, centrifugal pumps, electric motors, transmission shafts and machinery rollers. In all these cases, the 9423 seal protects bearings and gears from the entry of particles, extending the service life of the assembly. It is also used in equipment in the food, chemical and process industries, provided the lip material is compatible with the fluid to be retained. It is a standard solution for 50 mm shafts that require efficient radial sealing.

For correct installation, check that the shaft has a polished surface free of burrs, with adequate hardness to prevent premature wear. The housing must be clean and have the tolerance indicated for the 68 mm outer diameter. Lubricate the lip before inserting it and make sure the 8 mm height matches the housing depth. If the seal operates at high speed, consider the balance between the elastomer type and the operating temperature. If in doubt, consult our technical team to validate the selection.
