SKF South Africa recently provided a turnkey solution to assist an OEM customer in reducing lead times and streamlining planned downtime. In addition to the long lead times on seals for their underground earthmoving equipment, the customer was also unhappy with general service delivery from the supplier and took the decision to look for a single source supplier. The logical step was to approach SKF as the customer was already using SKF bearings and was happy with service delivery.
SKF’s OEM division suggested Speedi-Sleeve as the best sealing solution for the earthmoving equipment. The new generation Speedi-Sleeve uses a proprietary stainless steel material giving an optimised seal counter-face surface that minimises wear on both the sleeve and sealing lip. The contact surface is wear resistant. Imperceptible lubricant pockets enable the lubricant to reside on the sleeve and thereby prevent dry running of the sealing lip that otherwise can create excessive wear.
The thin-walled Speedi-Sleeve is simply pushed in position over the worn area. There is no shaft disassembly or machining involved, minimising costly downtime. Furthermore, since the installation tool is supplied with the sleeve, no special equipment is required to fit the seals.
In addition to supplying the Speedi-Sleeves, SKF also provided product training, assisted with planning of downtime to replace worn seals and helped the customer to achieve its goal of reducing supplier and vendor lists. The customer was extremely satisfied as it was now possible to deal with a single source supplier for both seals and bearings.
