Shaft Repair Sleeve

The shaft repair sleeves of Freudenberg Sealing Technologies are a fast and affordable solution for use in repairs for the permanent and reliable restoration of fault-free functioning of a radial shaft running surface. They are simply pushed over the worn running surface and thus represent a cost-effective alternative to replacement or complicated reworking of the worn shaft. In addition, shaft repair sleeves are used in the original equipment of machines, units or installations to avoid the complicated, costly and sometimes difficult machining of the running surface on the shaft. The shaft repair sleeves are used as an integrated running surface for the radial shaft seal in the tribological rotation sealing system. In addition to the radial shaft seal and the lubricant used, it is the third most important component in the sealing system.

The running surface for the radial shaft sealing ring is an essential machine element in the rotary sealing system. It must meet a number of technical requirements to achieve a good sealing effect and a long service life. Deep inlet tracks can lead to the original radial shaft seal ring dimension having to be replaced by a radial shaft seal ring with a smaller inside diameter. This may be the case, for example, if the original diameter has been significantly reduced during reworking of the shaft. This is where the shaft repair sleeves from Freudenberg Sealing Technologies come into play. In this way, in the event of repair, the running surface on the shaft can be restored quickly and, above all, cost-effectively, and no removal or finishing of the shaft is required. The repair time is reduced to a minimum, costly machine downtimes are eliminated, and the original seal dimension is retained. By using a shaft repair sleeve from Freudenberg Sealing Technologies in the event of repair, long-term fault-free operation can quickly be restored.

Freudenberg Sealing Technologies offers high quality yet cost-effective shaft repair sleeves. The complete range of shaft repair sleeves, including product and material data sheets, ordering options, prices and availability as well as dealer contacts, can be found in our FST e-catalogue.
