The DBH 8918 radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the entry of dust, water or contaminating particles. With dimensions of 45 mm shaft diameter, 70 mm housing diameter and 8 mm height, and an Lx design, it is used in gearboxes, pumps, electric motors and industrial equipment in general. MR Accesorios Industriales carries this brand and advises you so you choose the right seal for your application.

This item is a radial shaft seal from the DBH brand, identified with part number 8918. Its standard dimensions are 45.00 mm shaft diameter (d), 70.00 mm housing diameter (D) and 8.00 mm height (h). The Lx design corresponds to a configuration with a sealing lip and a spring that ensures continuous contact on the shaft. It is made with elastomers resistant to oils and greases, and its outer metal structure makes press-fitting into the housing easier. It is a key part for protecting bearings and mechanisms against lubricant loss and external contamination.

Typical applications for this seal include gearboxes, speed reducers, centrifugal pumps, electric motors, compressors and power transmission equipment. It is also used in agricultural machinery, conveyors and hydraulic systems where reliable sealing on rotating shafts is required. By keeping lubricant in place and blocking dust, it extends the service life of bearings and reduces maintenance downtime. It is a standard solution for 45 mm shafts rotating at moderate and high speeds.

For correct installation, verify that the shaft and housing diameters match the seal dimensions. The shaft must be clean, free of burrs and marks, and lubricated before inserting the seal. The housing must have an entry chamfer so the lip is not damaged. It is advisable to use a suitable installation tool that applies uniform pressure on the outer ring. If the seal works under high speed or temperature conditions, select an appropriate lip material. If in doubt, check with our technical team.
