This item is a DBH radial shaft seal, identified by the designation 9577. Its main attributes are: shaft diameter (d) of 28.57 mm, housing diameter (D) of 41.20 mm and height (h) of 6.35 mm. The Ls design corresponds to a seal with a sealing lip and metal case, suitable for applications requiring a barrier against oil or grease leaks and dust ingress. The DBH series is characterized by its robust construction and versatility in industrial environments.

Typical applications for this seal include gearboxes, pumps, electric motors, reducers and power transmission equipment. Its compact size makes it suitable for confined spaces where efficient sealing is required. It is commonly found in agricultural machinery, process equipment and lubrication systems operating with rotating shafts. Its main function is to protect bearings and internal components from external contamination and prevent lubricant loss.

For assembly, verify that the shaft and housing are clean and free of burrs. Lubricate the seal lip before installing it and use a suitable installation tool to avoid damage. Selection must be based on operating conditions: speed, temperature and type of fluid. If the original seal shows wear, also check the condition of the shaft and housing, since damaged surfaces can shorten the service life of the seal.
