Curviline is the name of the curvilinear rail product family. They are used for all non-linear special movements. Rails with constant or variable radii may be specified according to customer requirements, resulting in a highly flexible, economical solution. Curviline is available in two rail widths. The use of standard radii is recommended. All non-standard rail layouts and radii are possible as custom products, however extra lead time may result.

Performance characteristics:

- Available rail widths: CKR01/CVR01: 16.5 mm (0.65 in) and CKR05/CVR05: 23 mm (0.91 in)
- Max. slider operating speed on the rail: 1.5 m/s (59 in/s)(depending on application)
- Max. acceleration: 2 m/s² (78 in/s²) (depending on application)
- Max. effective length of the rail: 3,240 mm (127.56 in)
- Max. traverse: CCT08: 3,170 mm (124.8 in) and CCT11: 3,140 mm (123.62 in)
- Minimum radius for both sizes: 120 mm (4.72 in).
For non-standard radii, please contact Application Technology
- Radius tolerance +/- 0.5 mm (0.02 in), angle tolerance +/- 1°
- Temperature range: -30 °C to +80 °C (-22 °F to +176 °F)
- Rail and runner electrolytic zinc-plated and passivated (Rollon Aloy); increased anticorrosive protection on request
(see pg. 10 Anticorrosive protection)
- Rail material: CF 45
- Slider body material: Fe360
- Roller material: 100Cr6
- Roller pins lubricated for life


- By a simple adjustment of the eccentric roller pins (markings on bottom of roller), the slider has no clearance or is set with preload on the rails
- The recommended hole pitch is 80 mm (3.15 in) on the extended length
- Please indicate the precise rail shape and the desired hole pattern in a drawing
- Indicate if the design is a right or left version when ordering
- Composite rails are not recommended. For more information please contact Application Technology
- Resulting moment loads must be absorbed through the use of two sliders. For more information please contact Application Technology
