Cylinder Supports Compact Machine Design

June 15, 2018
Aventics' rodless cylinder is designed for a maximum speed of 6.5 m/s.

The RTC-SB (slide bearing) offers a very high load capacity, allowing engineers to draft even more compact machine designs. Equipped with a lubrication-free slide bearing, the cylinder is maintenance-free and resistant to water, chemicals and dirt. The slide play is optimally adjusted at the factory.


The rodless cylinder is designed for a maximum speed of 6.5 m/s (21.3 ft./s). The maximum stroke is around 6,000 mm (21.6 ft.). A wear-free magnetically attached exterior strip, scraper and sealing strip protect the cylinder from dust and dirt. Adjustable pneumatic cushioning extends the service life and ensures precise and gentle operation. The RTC precision cushioning can achieve “Ideal Cushioning” with the proper tools and adjustment. Form-fit connection technology with standardized mechanical interfaces simplifies machine design and speeds up assembly significantly since no re-adjustments are necessary.


The RTC-SB version with bore sizes ranging from 25 to 40 mm closes the previous gap between the basic version (RTC-BV) and the versions designed for higher loads, the RTC-CG (compact guide) and RTC-HD (heavy duty). RTC cylinders can be easily configured online with a part number assigned, CAD drawings and other documentation available in minutes.
