Ready-to-fit, complete linear systems for machine tools

Paul Boughton

For high precision motion control of machine tools and other production machinery, design engineers and end users increasingly require ready-to-fit, complete linear motion systems with integrated features such as sealing, lubrication, measuring and braking.

Schaeffler has developed a comprehensive range of standard, ready-to-fit complete linear guidance systems for machine tools, including profiled rail linear guides, linear actuators, shaft guidance systems, linear recirculating roller bearings and guideway assemblies, as well as a range of accessories such as damping carriages, seals, equipment for long term lubrication, clamping and mounting components.

However, manufacturers and design engineers are demanding higher load carrying capacities, longer term precision, improved dynamics and higher machine availability. In response to these requirements, Schaeffler’s premium quality X-life profiled rail linear guidance systems offer improved performance in terms of higher running speeds (typically 40 per cent higher) with unchanged load carrying capacity and rigidity for highly dynamic machine tools.

Schaeffler RUE range of roller type profiled rail linear guidance systems have been working reliably for many years in machine tool applications. RUE..E profiled rail units provide reliable support for the main axes of machine tools.

For feed and discharge systems, tool changers and handling systems, Schaeffler ready-to-mount linear actuators are the preferred choice. The MKUVS 42 LM, for example, is a linear actuator with a direct drive. This system is suitable for high speed, high precision positioning applications in machine tools and can also be used as a tool changer. The compact, integrated design of the linear actuator system means it requires less space to install. For extremely high loads that need to be transported in vertical axes, Schaeffler MDKUVE tandem actuator module is suitable.
