The DBH 5443 is a radial shaft seal built for rotating shafts. It keeps lubricant where it belongs and blocks dust, water and other contaminants from reaching the bearing area. Its dimensions are 12.70 mm shaft, 28.55 mm housing bore and 9.52 mm width, with an Lz configuration. This makes it a good fit for compact assemblies that still need dependable sealing. MR Industrial Accessories supplies this brand and can help you confirm the right choice.
This seal carries the DBH brand and the code 5443. The Lz design uses a sealing lip with a spring, which maintains steady contact against the shaft. The outer case is metal, and the sealing element is made of elastomers that stand up to wear and to the industrial oils typically found in gearboxes and pumps.
You will find this size in gear reducers, pumps, electric motors, drive shafts and other power transmission equipment. It also shows up in agricultural machines, production lines and material handling systems, where it shields bearings and bushings from contamination. Because the envelope is small, it suits housings with limited room.
Before installing, make sure the shaft and bore are clean and free of burrs. Apply a little of the same oil used in the equipment to the lip, then press the seal in squarely. Avoid striking the lip. When selecting a seal, consider shaft speed, operating temperature and the fluid being retained. If any of these are unclear, share your application details and we can advise.
For a replacement or an equivalent, send the code 5443 or the dimensions of your sample. We can search other brands or similar configurations while keeping the critical dimensions unchanged. We also manufacture housings and other components, but this seal is a DBH item that we supply.
