High Performance Linear Motion Systems Get Larger

High performance linear motion systems get larger A range of high performance, virtually maintenance-free linear motion systems with high levels of rigidity, accuracy and reliability, now include larger sizes of 130mm and 150mm versions. Responding to customer demand THK has extended its range of high performance Linear Motion systems still further, with the launch of two larger sizes to the Super Roller Guide (SRG) series. The new 130mm and 150mm versions incorporate THK's patented Caged Roller technology, which combines exceptional levels of rigidity, accuracy and reliability, as well as offering a virtually maintenance free component, for demanding conditions in manufacturing, automation or process applications. The new sizes are part of a product family giving high performance, smooth movement through low rolling resistance, and reduced levels of friction, heat and noise. The Caged Roller enhances rigidity and stiffness, while allowing loads to be moved or transferred smoothly and at extremely high speeds. With grease pockets between the roller retainer elements providing the exact amount of lubrication where required, this results in extended operating life and negates the need for short term maintenance. When compared with conventional roller guides the Caged Roller SRG gives far higher levels of radial and lateral stiffness, typically better than 40% higher while reverse radial stiffness is over 75% greater. Extensive testing has demonstrated that, in practical terms, these units have a far lower rolling resistance than conventional devices, with far fewer fluctuations in rolling resistance, making them far smoother in operation. These features ensure the SRG, whatever the size, is suited to tough and demanding industrial conditions. The new larger sizes are available with a choice of static load capabilities and either compact or flange type carriages, and are supported by THK's comprehensive UK customer and technical support services.
