Avoiding the need for costly repair of seal-worn shafts
A thin, metallic protective sleeve from SKF prevents abrasive damage to radial shafts, and costs a small fraction of the potential repair bill. In order to work efficiently, radial shaft seals must run against a smooth, round surface of the seal counterface.
If the counterface becomes worn – such as by a contaminant working itself under the sealing lip – the sealing system will begin to leak. Simply replacing the seal will not be enough. First, the shaft will have to be repaired so that it is flush with the new seal – at a cost of around £600. SKF Speedi-Sleeve combines a proprietary stainless steel material and manufacturing process into a protective sleeve that can be installed over the shaft to prevent damage.
