The DBH 9188 radial shaft seal is a lip seal designed for 25 mm rotating shafts, with a 40 mm housing bore and 8 mm height. Its function is to retain lubricant inside the assembly and prevent the ingress of dust, water or contaminating particles. It is used in gearboxes, pumps, electric motors and power transmission equipment. MR Accesorios Industriales supplies this brand and advises you so you choose the correct seal for your application.

This item is a radial shaft seal from the DBH line, identified with code 9188. Its dimensions are: shaft diameter 25 mm, housing bore 40 mm and height 8.00 mm. The Lr design corresponds to a single spring-loaded retaining lip, suitable for rotating shafts. The sealing lip, generally made of elastomer, runs on the shaft and the outer diameter fits into the housing. It is a common replacement part in equipment with rotating motion.

Typical applications include gearboxes, centrifugal pumps, electric motors, rollers and transmission systems. In all cases, the seal prevents oil or grease leaks and protects the bearings from contaminant ingress. It is also used in equipment in the food, chemical and process industries, where sealing is critical. If the seal fails, it can cause lubricant loss, premature bearing wear and unplanned downtime.

For correct installation, verify that the shaft measures 25 mm and the housing 40 mm, with 8.00 mm height available. The shaft surface must be clean, free of burrs and scratches, and it is advisable to lubricate the lip before inserting it. The seal is installed with the lip facing the fluid to be retained. If the shaft shows wear, consider an adjacent size or a seal with the lip in another position. Selection depends on speed, temperature and type of lubricant.
