SKF Speedi-Sleeves Resolve Cracking Issues
Melissa Larson | September 23, 2014
SKF Speedi-Sleeves, used with radial shaft seals in rotating machinery, resolve the micro-cracking issues typically associated with conventional chrome-plated sleeves. These sealing solutions enable users to quickly and efficiently replace worn sealing surfaces without time-consuming and unproductive machine disassembly and subsequent shaft regrinding. SKF Speedi-Sleeves install easily on shafts without using special equipment and can return machinery to service within minutes at a fraction of the cost of traditional shaft reworking. Standard SKF Speedi-Sleeve sizes can be supplied for shaft diameters from 11.99 mm/0.472 in. to 203.33 mm/8 in.
Speedi-Sleeves combine a proprietary stainless steel base material with a high quality, non-chrome surface finish, which eliminates the potential for development of micro-cracks common in chrome-plated versions. Such unwanted surface cracks (visible only by a scanning electron microscope) create a coarse surface finish, which tests show will accelerate seal wear by four times and, in turn, dramatically shorten seal life.
Applications include industrial gearboxes, fans, pumps, electric motors, off-highway and construction equipment, mining and mineral processing machinery, and all others where existing sealing systems have been compromised.
