Step 4 & 5: Relevant Data Compilation & Analytical Tables

Engineers buy based on hard performance metrics. I’ve compiled the verified catalog data into clean charts perfect for embedding in your article.

1. Core Operating Specifications

Context: Baseline performance data required for pneumatic system integration.

Feature	Specification Details	Citations
Available Sizes	10, 15, 20, 30, 40
Fluid Type	Air (non-lube)
Max. Operating Pressure	1.0 MPa
Min. Operating Pressure	Size 10: 0.2 MPa / Sizes 15 to 40: 0.15 MPa
Proof Pressure	1.5 MPa
Ambient & Fluid Temp	5°C to 60°C
Cushioning	Internal rubber bumper (except size 10)
Bearing Type	Ball bearing

2. Single Vane vs. Double Vane Capabilities

Context: Machine builders must choose between maximizing rotation angle or maximizing torque.

Configuration	Available Rotation Angles	Feature Advantage	Citations
Single Vane	90°, 180°, 270°	Specially designed seals and stoppers enable rotation up to 270°.
Double Vane	90°, 100°	Achieves twice the effective torque of the single vane type within the exact same outside dimensions (except size 10).

3. Allowable Kinetic Energy Limits (J)

Context: Exceeding kinetic energy limits is the #1 cause of internal actuator damage. Engineers actively search for these limits.

Size	Single Vane (Rubber Bumper Used)	Double Vane (Rubber Bumper Used)	Citations
10	0.00015	0.0003
15	0.001	0.0012
20	0.003	0.0033
30	0.02	0.02
40	0.04	0.15

(Note: Speed regulation range must be kept between 0.03 to 0.3 sec/90° for sizes 10-30, and 0.07 to 0.5 sec/90° for size 40).

4. Design & Installation Advantages

Context: Highlighting mechanical features directly answers the search intent of engineers looking for versatile mounting options.

• Unrestricted Auto Switch Mounting: Switches can be moved anywhere along the circumference of the rotary actuator, allowing them to be mounted at the absolute optimum position.
• Built-in Reliability: The use of ball bearings across the series supports heavy thrust and radial loads, drastically improving durability compared to standard bushing designs.
• Copper-Free Options: Specialized 20-CRB2BW series models prevent any adverse effects to color CRTs caused by copper ions or fluororesin, making them ideal for specialized electronics manufacturing.
• Angle Adjustment: Retrofittable angle adjusters allow you to dial in specific rotations (e.g., 0 to 240° for sizes 15-30) without buying a completely new actuator.
