6 1053 From one simple but inspired solution to a misalignment problem in a textile mill in Sweden, and fifteen employees in 1907, SKF has grown to become a global industrial knowledge leader. Over the years, we have built on our exper-tise in bearings, extending it to seals, mecha-tronics, services and lubrication systems. Our knowledge network includes 46 000 employees, 15 000 distributor partners, offices in more than 130 countries, and a growing number of SKF Solution Factory sites around the world. Research and development We have hands-on experience in over forty industries based on our employees know-ledge of real life conditions.

7 In addition, our world-leading experts and university part-ners pioneer advanced theoretical research and development in areas including tribol-ogy, condition monitoring, asset manage-ment and bearing life theory. Our ongoing commitment to research and devel opment helps us keep our customers at the forefront of their industries. Meeting the toughest challenges Our network of knowledge and experience, along with our understanding of how our core technologies can be combined, helps us create innovative solutions that meet the toughest of challenges. We work closely with our customers throughout the asset life cycle, helping them to profitably and re spon sibly grow their Solution Factory makes SKF knowledge and manu facturing expertise available locally to provide unique solutions and services to our with SKF IT and logistics systems and application experts, SKF Authorized Distributors deliver a valuable mix of product and application knowledge to customers for a sustainable future Since 2005, SKF has worked to reduce the negative environmental impact from our operations and those of our suppliers.

8 Our continuing technology development resulted in the introduction of the SKF BeyondZero portfolio of products and services which im-prove efficiency and reduce energy losses, as well as enable new technol ogies har-nessing wind, solar and ocean power. This combined approach helps reduce the en vir-on mental impact both in our oper ations and our customers oper the knowledge engineering company45 BearingsSKF is the world leader in the design, development and manufacture of high performance rolling bearings, plain bearings, bearing units and maintenanceCondition monitoring technologies and main-tenance services from SKF can help minimize unplanned downtime, improve operational efficiency and reduce maintenance solutionsSKF offers standard seals and custom engineered sealing solutions to increase uptime, improve machine reliability, reduce friction and power losses.

10 Achieve higher energy and resource efficiency, and optimize designs for long service life and reliability. Innovative solutions Whether the application is linear or rotary or a combination, SKF engineers can work with you at each stage of the asset life cycle to improve machine performance by looking at the entire application. This approach doesn t just focus on individual components like bearings or seals. It looks at the whole application to see how each com po nent in-teracts with each optimization and verificationSKF can work with you to optimize current or new designs with proprietary 3-D mod-ell ing software that can also be used as a virtual test rig to confirm the integrity of the design.
