2 Schaeffler UK Engineering Excellence Training your staff for the future challenges in the selection, operation, maintenance and reliable operation of rolling bearings The correct selection, maintenance and monitoring of rolling element bearings is crucial to maximising the life and reliability of plant and equipment. Just selecting the bearing is not enough, it must be mounted properly in the first place, have the correct type and amount of lubricant and be relubricated at the right interval. The loss of a critical piece of plant or equipment will often result in costly lost production or downtime, so Condition Monitoring can be successfully used to minimise disruption and hence save costs. The challenges facing our customers are important to us and the training courses outlined here have been structured to ensure that we give our customers the maximum support possible during the initial design process through to the successful operation and monitoring of their plant and equipment. As a company, we believe that flexibility is key to the future and, in addition to the training modules outlined here, we can offer bespoke courses to meet the individual needs of our customers. Supported by staff with many years' experience in the design and application of rolling bearings, our instructors can offer expert guidance and advice both during and after the training course. We look forward to seeing you at our new training facilities in Sutton Coldfield. Kate Hartigan Managing Director Schaeffler UK PAGE 2 PAGE 3

The Group, which remains a family-owned concern, markets its products under three world class brands INA, FAG and LuK. INA was formed just after the Second World War and made its big breakthrough in 1949 with the invention of the needle roller and cage assembly. This product is still in use in its original form and the INA product range has been expanded to include ball and roller bearings, spherical plain bearings, housed units and linear bearings and systems. In addition to its bearing products, INA has developed into one of the world s foremost suppliers of automotive engine components and works in partnership with many automotive manufacturers to develop solutions to their requirements for more efficient, economical and environmentally friendly vehicles. The history of FAG dates back to 1883 and the development of a ball grinding machine which made it possible, for the first time, to produce a perfectly round steel ball. In the intervening years, the FAG product range has expanded to include cylindrical, spherical and tapered roller bearings, angular contact and deep groove ball bearings. The combined INA and FAG standard catalogue now comprises over 40,000 standard products for use in over 60 industrial sectors ranging from power transmission, mechanical handling, construction, mining and quarrying, steel and paper to automotive and aerospace. Support for these industries is provided by Schaeffler's Industrial Aftermarket Division (IAM) which develops and supplies a wide range of online and offline condition monitoring equipment designed to provide warnings of potential problems and to minimise unplanned plant and machinery shutdowns. IAM also supplies a wide range of specially developed maintenance tools and equipment. The Schaeffler Group maintains its leading edge by constantly developing products to meet the specific needs of its customers. To this end more than 5000 staff worldwide are directly involved in research and development, and, on average, their efforts result in over 1200 patent registrations per year. located at Sutton Coldfield in the West Midlands, is the headquarters for all sales, marketing, engineering and logistics for both the INA and FAG brands in the UK. In-house application and design engineers work with carefully selected distributors and direct with end users to deliver the best engineered and most cost effective solutions to each individual requirement.
