The product range: one basis, three variants

The rodless cylinders offer optimized stroke length in a compact size. This saves space and facilitates machine design. The range of applications extends from piston diameters of 16 mm up to 80 mm and stroke lengths up to 9,900 mm. The cylinders feature extreme repeatability and cover a large speed range from 0.01 m/s to >20 m/s.

The comprehensive range with many variants and options enables configurations that are individually tailored to the application.

The RTC cylinders offer compelling advantages at all levels

High-power OVALDRIVE

An oval piston design permits unusually high load and torque absorption, as well as ultra-compact machine designs.

  • High load capacity and rigidity
  • The wide slot offers optimized belt return and smoother running
  • Lateral torques are absorbed by the piston
  • For compact machine designs


High-tech grease and specific sealing material for smoother running and extended service life, coupled with decreased wear.

  • Compatible with a large speed range from 0.01 m/s up to >20 m/s
  • Can be used in a wide temperature range
  • Minimum leakage and high energy efficiency
  • Cushioning pins on the pistons and enlarged air ducts in the profile covers enable high speeds and ideal pneumatic cushioning

Reliability and long service life

Wear-free magnetically attached exterior strip, scraper, and sealing strip protect the cylinder from exterior effects, make it dust and dirt resistant, and increase its service life.

  • Scraper and cover strip made of stainless steel provide optimal dust protection
  • Piston and slide in a single unit increase the rigidity and decrease machine downtimes
  • Special sealing strip (steel wire reinforced polyurethane): extremely stable material prevents expansions that would interfere with the function

RTC with intermediate stop

The multi-position solution enables more than one intermediate stop. In addition, travel can continue in the same direction following an intermediate stop.

The RTC cylinders offer compelling advantages at all levels.

Easy-2-Combine interface

Standardized mounting interfaces for direct connection of AVENTICS components.

Less moving mass as no transition plates are required. Simplified machine design and reduced mounting effort.

Air connections on both sides

Flexible mounting options thanks to free choice of air connections on both sides. Compressed air connection indicators in the end covers indicate the direction of movement.

Sensor slots on both sides

Sensors are visible and mountable from the top and the side. The special design allows mounting of two sensors in each slot, including an indentation for cables.

Examples of application

RTC-TD for safe and efficient train door applications

With the RTC-TD, a cylinder that was specifically developed for train door applications, AVENTICS is introducing an innovative all-round solution that offers clear advantages over electromechanical and pneumatic systems: More compact design at a lower cost and longer service life. Thanks to the integrated valve technology, including extended pneumatic cushioning and emergency ventilation, the RTC-TD is not only particularly lean and light, but also easy to install. The speed and cushioning are preset, but can be adjusted to the individual requirements at any time.

Industry sectors

The RTC-BV is ideal for long horizontal stroke movements for conveying or cutting. Regardless of whether it is applied as a high-speed cutting knife or for rather slow, constant transporting.
