RTC Rodless Cylinders

RTC Rodless Cylinders - advantages at a glance

  • Robust, oval piston design
  • Sturdy, compact profile
  • Adjustable pneumatic end-cushioning
  • 4 versions available: RTC-BV Basic Version, RTC-CD Compact Guide, RTC-HD Heavy Duty, RTC-SB Slide Bearing
  • Easy installation of cylinder using two styles of foot mounts, or choose end cover mounts
  • High Speed: Speeds up to 21 feet per second

Space saving, high performance

The Series RTC is the latest generation of rodless cylinders from AVENTICS, building on years of experience with rodless cylinder design. The RTC features a very robust, virtually leak-free design with high speed capability. Offering inch and metric options in four main versions, the RTC can be custom configured on-line. By choosing the Easy-To-Combine option, the RTC can be combined with other AVENTICS standard actuators to build modular automation systems.

Product Features:

  • Oval-shaped piston provides greater resistance to side load and a low overall height
  • Available in inch stroke/ports or metric stroke with ISO G (BSPP) ports
  • Bore sizes: 5/8" (16mm), 1" (25mm), 1 1/4" (32mm), 1 1/2" (40mm), 2" (50mm), 2 1/2" (63mm) and 3" (80mm)
  • Stroke length maximums vary by version and bore size, up to 389" (9900mm)
  • Sensor magnet standard
  • Shuttle and piston body in one piece, a robust design integrated for high strength and long life
  • Cushioning: adjustable pneumatic end-cushioning plus impact bumpers in polyurethane reduce noise and absorb impact forces

The product range: one basis, four variants

RTC-BV – Basic Version

Internal guiding thanks to a unique oval piston design. Typical application areas include: material flow, door openers, cutting and drive processes.

RTC-CG – Compact Guide

Compact precision guiding. Typical application areas: medium loads in settings with limited space.

RTC-HD – Heavy Duty

High-precision guiding for heavy loads. Typical application areas: as a base axis for handling applications, very high load capacity

RTC-SB - Slide Bearing

Integrated adjustable slide bearing fuide. Typical applications: material handling, stop gates, and pushers.

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.

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 ventiliation, the RTC-TD is not only lean and light but also easy to install! The speed and cushioning are preset, but can be adjusted to 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.
