MR Accesorios Industriales supplies this brand so you can meet your sealing needs.

This item is a radial shaft seal from the DBH brand, identified with the code 5148. Its dimensions are 40.00 mm shaft diameter (d), 52.00 mm housing diameter (D) and 7.00 mm height (h). The Lx design corresponds to a configuration with a sealing lip and a spring that ensures continuous contact on the shaft. It is manufactured with elastomers and a metal case that provide resistance to wear and external agents.

Typical applications for this seal include gearboxes, centrifugal pumps, electric motors, compressors and bearings in general. In all cases, its function is to confine oil or grease and protect internal components from contamination. It is commonly found in equipment where the shaft rotates at moderate speeds and operating conditions require a reliable barrier against leaks.

To install this seal correctly, verify that the shaft and housing are clean and free of burrs. Lubricate the lip with the same oil or grease it will seal. Insert the seal perpendicular to the shaft, applying uniform pressure on the outer circumference. Make sure the lip does not turn over and that the spring is correctly positioned. If the shaft shows wear, consider whether a repair sleeve is needed.
