SMC CDRQ2BS20TN-180C Compact Rotary Actuator (CDRQ2BS20TN180C)
1. Product Overview
The SMC CDRQ2BS20TN-180C (also referred to as CDRQ2BS20TN180C) is a premium compact rotary actuator from SMC’s CRQ2 series, featuring a precision rack-and-pinion drive mechanism. Designed for industrial automation, this thin-type pneumatic actuator converts linear air pressure into stable 180° rotational motion, with an adjustable angle range of ±5° to meet fine-tuning requirements. Boasting a 20 mm bore diameter and single-shaft design, it delivers reliable torque output for applications like part indexing, workpiece flipping, precision positioning, and clamping in automotive assembly, electronic manufacturing, and packaging machinery. Its lightweight aluminum alloy construction and integrated mounting interfaces ensure seamless integration into confined spaces, while complying with SMC’s strict precision standards for long-term operational reliability.
2. Main Functions
|
Function
|
Detailed Description
|
|---|---|
|
180° Precision Rotary Motion
|
Delivers standard 180° swing with ±5° angle adjustment, powered by a rack-and-pinion system for backlash-minimized rotation and consistent positioning accuracy.
|
|
Double-Acting Operation
|
Converts pneumatic pressure into bidirectional rotational force, supporting automated start/stop cycles via solenoid valves and PLC-based control systems.
|
|
Built-In Air Cushioning
|
Equipped with air cushions at both limit positions (0° and 180°) to absorb impact, reduce operational noise, and prevent component damage from sudden stops.
|
|
Magnetic Sensor Compatibility
|
Features grooves for mounting magnetic proximity sensors (not included) to detect rotational position, enabling real-time signal feedback for closed-loop control.
|
|
Versatile Mounting
|
Integrated mounting holes on front, rear, and side surfaces allow horizontal, vertical, and flange installation, adapting to diverse automation layouts.
|
3. Technical Features
-
Dual Rack-and-Pinion Drive: Adopts carbon steel gears and dual racks to eliminate tooth gap, ensuring smooth, uniform torque output throughout the 180° stroke with high repeatability.
-
Lightweight Durable Construction: Cylinder barrel and end caps are made of hard-anodized aluminum alloy, balancing structural rigidity with lightweight design and corrosion resistance.
-
Oil-Free Operation: Designed for maintenance-free, oil-free lubrication, reducing operational costs and making it suitable for clean environments like electronic component assembly.
-
Broad Operating Range: Functions reliably at 0.1–1.0 MPa air pressure and 0–60°C ambient temperature, adapting to harsh industrial conditions with relative humidity ≤85%.
-
Reliable Sealing System: Double NBR rubber seals prevent air leakage, maintaining stable pressure and performance even at maximum operating pressure.
-
Single-Shaft Design: Features a standard single output shaft with precision threading, facilitating easy connection to couplings, brackets, and other mechanical components.
