The DBH 9517/85 radial shaft seal is a lip seal designed to stop lubricant from escaping and keep contaminants out of rotating equipment. With dimensions of 40 mm shaft, 56 mm housing and 8.50 mm height, it is mounted in crankcases, gearboxes and pumps where the shaft rotates inside a fixed housing. Its Lt design and the DBH brand make it a reliable option for industrial maintenance. MR Accesorios Industriales carries this brand and advises you so you choose the right seal.

This item is a radial shaft seal from the DBH brand, identified by the designation 9517/85. Its dimensions are 40 mm shaft diameter, 56 mm housing diameter and 8.50 mm height. The Lt design corresponds to a single-lip configuration with spring, suitable for rotating shafts with lubrication. The 9517/85 code places it within the DBH line and lets you confirm its interchangeability with other similar references. It is a sealing component that works by direct contact on the shaft.

Typical applications for this seal include gearboxes, electric motors, centrifugal pumps, mixers and transmission equipment. In all these cases, the seal prevents oil or grease leaks and protects the bearings from dust and moisture. It is also used in machine tools and continuous process equipment, where preventive maintenance requires replacing seals before they fail. Its size of 40 x 56 x 8.50 mm makes it common on medium-size power transmission shafts.

To mount this seal correctly, verify that the shaft has the right hardness and surface finish, and that the housing is clean and free of burrs. Lubricate the lip before inserting it and avoid hitting it during mounting. Selection must consider shaft speed, working temperature and the type of lubricant. If the previous seal failed, check the condition of the shaft and housing: excessive wear or runout shortens the service life of any seal.
