The DBH 9188 is a radial shaft seal from the DBH line, sized for a 25 mm shaft, a 40 mm housing bore and an 8.00 mm height. Its Lr design features a single spring-loaded lip that keeps lubricant in and contaminants out of rotating equipment. MR Industrial Accessories supplies this brand and helps you match the right seal to your application.
This seal carries the code 9188. The dimensions to check before ordering are shaft 25 mm, housing bore 40 mm and height 8.00 mm. The Lr configuration uses one lip with a spring, which is a common choice for rotating shafts. The elastomer lip runs against the shaft while the outer diameter seats in the housing, making it a typical replacement part in machinery with rotating motion.
You will find this seal in gearboxes, centrifugal pumps, electric motors, rollers and transmission systems. In each case it holds oil or grease inside the assembly and blocks dust, water and particles from reaching the bearings. Food, chemical and process industry equipment also relies on this type of seal where leakage is a concern. A failed seal can lead to lubricant loss, bearing wear and unplanned downtime.
During installation, confirm the shaft is 25 mm, the housing is 40 mm and there is 8.00 mm of height available. The shaft surface should be clean and free of burrs or scratches. Lubricating the lip before pressing it in helps avoid damage, and the lip should face the fluid being retained. If the shaft shows wear, a seal with the lip in a different position may be an option. Speed, temperature and lubricant type all affect the final selection.
If you need an equivalent or a different size, send us code 9188 or your current dimensions. MR Industrial Accessories can search for alternatives within the DBH brand or other brands we supply, and we can advise you when mounting space is limited or a special material is required.
