The DBH 9779 radial shaft seal is a lip seal that prevents oil or grease leaks and blocks the entry of dust and water in equipment with a rotating shaft. Due to its dimensions of 53 mm shaft, 69 mm housing and 16 mm height, it is used in gearboxes, pumps, electric motors and industrial transmissions. MR Accesorios Industriales carries this official 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 part number 9779. Its dimensions are 53.00 mm shaft diameter, 69.00 mm housing diameter and 16.00 mm height. Design A 304 corresponds to a single lip configuration with spring, designed to retain lubricant and exclude contaminants under continuous operating conditions. The 9779 nomenclature groups these specific dimensions within the DBH catalogue.

Typical applications for a seal of this size include gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. In all cases, the seal is mounted on the shaft and inside the housing to separate the lubricant from the outside environment. It is a wear part that should be replaced when oil leaks or dirt ingress appear.

To select and mount it correctly, verify that the shaft diameter is within the recommended tolerance and that the contact surface is clean and free of burrs. The housing must have the appropriate diameter and depth to accommodate the 16 mm height. Lubricate the lip before installing and avoid hitting it during mounting. If the shaft shows wear, consider a neighbouring size or a seal with the lip in another position.
