Application Examples and Options

The cylinders are suitable for various automation tasks including rotary units, tool changers, linear actuators, grippers, and robot kits. The document references compatible accessories such as profiles, brackets, suspensions, sensors, and quick changers.

Critical Information and Best Practices

• Ensure compressed air quality meets ISO 8573-1:2010 [7:4:4] standards to maintain cylinder performance and longevity.
• Use FDA-H1 food-grade grease for applications requiring food safety compliance.
• Select stroke length and model variant based on required force and space constraints.
• Consider optional magnetic sensors for precise position feedback.
• Follow mounting hole specifications and air connection standards for proper installation.
