Aventics rodless cylinders cover two product families: the CKP slot cylinder series with bores from 16 to 32 mm and strokes up to 1,240 mm, in CKP-CL (closed slot) and CKP-TG (through guide) variants, and the heavy-duty RTC-HD series with a 63 mm bore and strokes up to 1,000 mm. Rodless cylinders require no axial space for an extending piston rod, halving the overall installation length compared with conventional cylinders for the same stroke.
| Series | Drive principle | Bore | Max. stroke |
|---|---|---|---|
| CKP-CL | Magnetic, closed slot system | 16 / 25 / 32 mm | 1,240 mm |
| CKP-TG | Mechanical, open slotted tube | 25 / 32 mm | 1,000 mm |
| RTC-HD | Mechanical, heavy duty | 63 mm | 1,000 mm |
Typical applications: Linear axes for tool and part transfer in assembly automation, gantry systems for Cartesian handling cells, positioning slides in food and packaging machinery, transfer units in cleanroom applications (CKP-CL without open slot), and transverse feeds and shift axes where machine installation space is limited.
