Sleeves Resolve Micro-Cracking Issues

SKF Speedi-Sleeves used with radial shaft seals in rotating machinery resolve the micro-cracking issues typically associated with conventional chrome-plated sleeves, according to the company.  The sealing solutions enable users to replace worn sealing surfaces without requiring machine disassembly and subsequent shaft regrinding.  SKF Speedi-Sleeves install on shafts without using special equipment and can return machinery quickly to service.

SKF Speedi-Sleeves combine a stainless steel base material with a non-chrome surface finish, which eliminates the potential for development of micro-cracks. The SKF base sleeve material and surface finish maximize resistance to wear, provide superior strength and ductility, and optimize overall seal performance and reliability, according to the company.

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.

Standard SKF Speedi-Sleeve sizes can be supplied for shaft diameters from 11.99mm / 0.472 in. to 203.33mm / 8 in.  For abrasive environments and/or for applications integrating filled PTFE-filled seals, SKF Speedi-Sleeves are available in “Gold” versions integrating an enhanced surface coating for higher performance.
