The DBH 5818Sil is a radial shaft seal with an Lz design, sized for a 12 mm shaft, 22 mm housing and 7.00 mm height. It keeps lubricant in and contaminants out of small-shaft equipment, and MR Industrial Accessories supplies it to maintenance and purchasing teams across the United States and Latin America.

This lip seal mounts in the housing and runs against the rotating shaft. The Lz design uses a sealing lip with a spring, where the elastomer contacts the shaft while the outer diameter holds the fit in the housing. Shaft 12 mm, housing 22 mm, width 7.00 mm. Because the lip is delicate, handle the seal carefully and avoid nicks during installation.

You will find this size in small electric motors, gearboxes, water and oil pumps, compressors, fans and low-power transmission equipment. Agricultural machinery, power tools and process equipment also use it to contain lubricant and keep bearings free of dust, water or particles. Match the lip material and spring to the fluid, temperature and peripheral speed of your application.

Before installing, inspect the shaft for burrs or wear and make sure the housing is clean and mark-free. Lubricate the lip, then press on the outer diameter with an installation tube rather than on the lip itself. The 7.00 mm height should sit flush or slightly recessed depending on the housing. If the shaft surface is worn, a repair sleeve can restore the fit.

To find an equivalent or a different size, send the code 5818Sil or the dimensions 12 x 22 x 7 mm along with the application details. Include the fluid being retained, the working temperature and the shaft speed so the selection can be guided properly. The technical team can suggest alternatives in other brands or configurations within the same radial shaft seal category.
