While providing superior performance in terms of leakage and friction properties, FR200 starts relieving pressure build-up at a very early stage, which enhances overall system reliability. The main features of FR200 are, n Special lip geometry n Shortened sealing lip n Excellent static and dynamic tightness of the seal n Improved extrusion strength n Pressure- relief segments n Reliable return pumping capacity n Reduced contact areas All tools are ready for the initial list of dimensions. FR200 has a very critical design concept. For this reason, the dimension range will be limited to the appropriate cross-sections, mostly ISO dimensions. In line with the target segments and applications, the initial dimension range of FR200 will extend up to Ø160. In general, FR200 is an ideal solution in all applications where low friction is required specifically forklifts, platform lifts, injection molding machines, gas springs, machine tools and hydraulic power steering systems.

Product News The ultra-fast brushless DC motor Maxon motor launches new high-speed motors that are configurable online. The new ECX brushless motors are quiet and feature very high efficiency. These brushless drives are ideal for use in hand-held surgical tools and industrial spindles. With Maxon Motor’s configurator, it is easy to put together a customized DC motor- including gearhead, encoder and controller, as per the required specifications. Now, in addition to the brushed motors, the customer can also configure three new high speed brushless micro motors. The ECX motors are available with diameters of 8, 16 and 19 mm achieving speeds of up to 120,000 rpm. All three high-speed motors are now available in Maxon’s online shop, where customizing the drives is easy. This means that customers can fit the drives with specific mechanical and electrical components specific to their application needs. For example, with the ECX 8 mm, the GPX planetary gearheads and ENX 8 encoders are available. lt is also possible to customize the shaft lengths, winding types, ball bearings and much more. Lean, automated processes ensure that all configurable drives are ready for shipment within 11 working days. Faulhaber brings affordable micromotor in the market Faulhaber is expanding its range of drives in the medium power range with the new 1727…CXR DC-micromotor, and is adding an extremely compact drive to the CXR series. A powerful magnet gives the graphite-commutated motor a high power density with a continuous torque of 4.9 mNm. It generates this power in a housing that is just 17 mm in diameter and 27 mm in length. The temperature range in which it can be used is from -30 to +100 °C. The CXR series includes DC motors with an extremely attractive price/ performance ratio. The drives of the series CXR, can be combined with encoders and with precision gearheads from a coordinated product range. It can be optionally actuated with the motion controller for speed control or positioning. The compact dimensions of the 1727…CXR and its performance data opens up a wide range of potential applications. Frequency converter from Schneider Electric Schneider Electric supplies frequency converters especially for mechanical engineering in their Altivar Machine series. The first two models are Altivar 320 for simple applications and Altivar 340 for high-tech applications. The Altivar 340 is suited to the control or regulation of servo motors, asynchronous motors, reluctance motors and induction motors from 0.75 to 75 kW, in ambient temperatures up to 60 °C (140 °F). The Altivar 320 is suited to controlling three-phase asynchronous motors and synchronous motors from 0.18 to 15 kW. It has openPLC library and SoMachine library as well as integrated logic. Both devices offer Safe Torque Off for applications up to SIL 3/PL e, and are suitable for printed circuit coating according to class 3C3 for very rough surroundings. With the multi-loader function the devices can be configured without a power supply without removing from the packaging. Typical areas of application are the wood-working industry and the packaging industry or the field of handling and lifting.
