Innovative Actuation Solutions for Every application
Clamping and workholding applications are often underestimated. What seems like a simple sequence of motion and force quickly becomes a demanding actuation challenge once accuracy, cycle life, shock loading, and consistency are considered.
Clamping applications require precise, repeatable force, often over high cycle counts, while tolerating shock loads and side loads. Because of this, clamping applications tend to expose the limitations of traditional actuator technologies quicker than other use cases.
Understanding why this happens can help engineers make better clamping actuator selection decisions and avoid long-term performance and maintenance issues.
Clamping requirements vary widely across industries and machines. Some applications are simple and low force, while others demand high force, tight control, and long hold times. Common clamping actuation requirements include:
Pneumatic actuators are widely used for low-force, simple clamping due to their speed, low upfront cost, and ease of use.
However, clamping applications quickly reveal their limitations:
Screw-driven actuators are commonly used for low to medium force clamping, especially where cleanliness and positioning accuracy are important.
In clamping applications, several challenges emerge:
Hydraulic cylinders remain a common choice for medium to high force clamping applications, offering pressure-based force control and the ability to actuate quickly using large pumps and motors.
However, clamping applications highlight several inherent drawbacks:
Kyntronics’ Hybrid Linear Actuators (SHA) combine the strengths of electro-mechanical and hydraulic technologies while minimizing their weaknesses — making it uniquely adaptable to the full range of clamping requirements.
In clamping applications, hybrid actuation systems offer several key advantages:
Clamping applications require engineers to look beyond peak force ratings and ask deeper questions:
By answering these questions, engineers can better select a reliable actuation solution for their application.
