The DBH 5920 is a radial shaft seal from the DBH line, built to keep lubricant where it belongs and to block dust, water and other particles from reaching the bearing or bushing. Its Lz design covers one-direction sealing duties. The size is given as shaft 130 mm, housing 160 mm and width 15 mm, which makes it a compact option for gearboxes, pumps and reducers with tight axial room. MR Industrial Accessories LLC supplies this brand and can help you confirm the correct seal for your equipment.

Reading the code is the fastest way to check fit. The three figures in the designation follow the usual order for this type of seal: 130 mm for the shaft, 160 mm for the housing bore and 15 mm for the height. The Lz suffix identifies a particular lip and body configuration inside the DBH range, intended for radial sealing in one direction. Confirm all three values against the machined seat before ordering, since a seal that is even slightly off will not seat or seal properly.

These seals are common in gearboxes, centrifugal pumps, mixers, conveyors and other power transmission assemblies. Their job is to hold oil or grease inside the housing while keeping external contamination out of the lubricated zone. You will also find them on machine tools and process equipment where a dependable shaft seal matters. Because the lip is a wear item, plan periodic checks and replace the seal when you see weeping, hardening or cracking at the lip.

Correct installation protects the seal and extends its working life. The shaft surface should be ground, with no splines or burrs that could cut the lip, and reasonable roughness and hardness help. Lubricate the lip with the same oil or grease used in the application, press the seal in squarely, and avoid hitting it directly. If the shaft is worn, a repair sleeve or a different size may be the better route.
