The DBH 6740 seal is a single-lip radial seal that mounts on rotating shafts to retain lubricant and block the entry of dust, water or particles. Its Lz design and dimensions of 50 mm shaft, 84 mm housing and 10 mm height make it suitable for gearboxes, pumps and power transmission equipment where bearings and gears must be protected. MR Accesorios Industriales carries this official brand and advises you on choosing the correct seal for your application.

This item is a DBH radial shaft seal identified by part number 6740. Its dimensions are 50.00 mm shaft diameter, 84.00 mm housing diameter and 10.00 mm height. The Lz design indicates a spring-loaded lip configuration that ensures constant contact on the shaft. The outer body is metal and the sealing lip is elastomer, which allows it to work with standard industrial oils and greases. Always verify that all three dimensions match the housing and shaft before installing.

Typical applications for a seal of these dimensions include gearboxes, speed reducers, centrifugal pumps, electric motors and belt or chain drive equipment. In all cases, the function is the same: keep lubricant inside the assembly and prevent contaminants from entering that would accelerate wear on bearings and gears. It is also used on fan, mixer and conveyor shafts where there is continuous rotation and the presence of dust or moisture.

To correctly select this seal, take into account the shaft rotation speed, working temperature and type of lubricant. The spring-loaded Lz design is suitable for medium speeds and requires a ground shaft surface free of splines to avoid damaging the lip. During installation, lubricate the lip with the same grease or oil used in the equipment, insert the seal perpendicular to the shaft and verify that it seats fully in the housing. A crooked installation or a dry lip causes premature leaks.
