The DBH 8486/85 is a radial shaft seal used to keep lubricant in and contaminants out of rotating equipment. It fits a 40 mm shaft, a 56 mm housing and has an 8.50 mm height. The Lt design indicates a sealing lip with a metal case. You will find it in gearboxes, pumps, electric motors and other industrial machinery. MR Industrial Accessories supplies this brand and can help you confirm the right seal for your application.
This seal carries the code 8486/85 and belongs to the DBH line. Its three key dimensions are: shaft 40 mm, housing 56 mm, height 8.50 mm. The Lt configuration means a single sealing lip combined with a metal outer body, which provides a press fit in the housing and dynamic sealing against the shaft. The lip elastomer and case material are verified against the manufacturer's data for each application.
Common uses include gearboxes, centrifugal pumps, electric motors, compressors and transmission units. In these positions the seal retains oil or grease while blocking dust, water and particles that would otherwise reach bearings and gears. You will also see it in agricultural equipment, process lines and conveyor drives. Its small cross-section suits installations where space around the shaft is limited.
Proper installation starts with checking the shaft surface and the housing bore. The shaft should meet the recommended hardness and roughness, and the housing must be clean, dry and free of burrs or scratches. Lubricate the lip before pressing the seal in, and make sure it enters squarely so it sits perpendicular to the shaft. When choosing a seal, take into account shaft speed, operating temperature and the fluid being sealed. If the shaft is worn, an auxiliary lip or a wear sleeve may be needed.
