Rodless cylinders feature oval bores and optional guides
Bosch Rexroth is introducing four versions of a new RTC series of rodless pneumatic cylinder. A key feature to Rexroth's RTC (rodless thrust cylinder) series is its oval piston construction, which allows high loads and torques to be used, resulting in a space-saving design in comparison with the more common round piston design. The cylinders in the Rexroth RTC series are available is four versions, designed to suit applications calling for cost-effectiveness, high precision, high performance or compact dimensions.
While the basic version RTC-BV is suitable for universal use, Rexroth's RTC-CG (Compact Guide) version packs high-precision features into compact dimensions. The RTC-EG (E-Line Guide) version represents the most cost-effective guided version of rodless cylinders from Rexroth, and the RTC-HD (Heavy Duty) version is designed for handling extremely heavy loads.
The RTC is available in 'diameters' from 16-80 mm (5/8 - 3inch), and a maximum stroke length of 9900mm (32.5 ft), depending on size and version, and is available with both ISO-G or NPT port configurations.
A configuration program is available online to help designers determine the most appropriate cylinder to suit a specific application. Also available on the Rexroth website is a calculation program for comparing cylinder dimensions with required flow rate, plus corresponding CAD data.
All RTC guided cylinders are delivered with an Easy-2-Combine interface that enables the units to be combined easily with other components with this interface to form multi-axis systems. This simplified machine design and construction will save engineers both time and money.
