Description

CRQ2 Series: High-Precision Compact Rotary Actuator

Rack & Pinion Design for Versatile Automation

The CRQ2 Series is a compact, rack-and-pinion style rotary actuator engineered for high-performance automation tasks. Designed with a double-piston construction, it provides a stable, backlash-free torque output in a space-saving package where the actuator body itself serves as a mounting flange.

Key Technical Features

Integrated Angle Adjustment: Each unit is equipped with an adjustment mechanism allowing for a precision tuning range of ±5° at each rotation end.
Double Piston Construction: The rack-and-pinion design utilizes two pistons to ensure consistent torque and eliminate backlash throughout the rotation.
Compact Integration: Piping ports and auto-switch mounting slots are strategically placed on the same side of the body to facilitate one-end installation and realize significant space savings.
Mounting Versatility: Both single-shaft and double-shaft configurations are available across all sizes (10, 15, 20, 30, and 40).
Easy Positioning: The body features a built-in pin hole for rapid and accurate centering during installation.

Shaft Configuration Options

The CRQ2 series offers several shaft types to meet diverse application requirements:

Single Shaft (S): Standard configuration with one output shaft.
Double Shaft (W): Features output on both ends.
Round Shafts (T/K): Available in single (T) or double (K) round profiles without keys.
Custom Profiles: Variations include four chamfers (X/Z) or shafts with specific keyways (Y/J).

Ordering Configuration Guide

To ensure the correct specification for your system, use the following standardized format:

Magnet Ring: Built-in as standard for auto switch compatibility.
Size: Select from 10, 15, 20, 30, or 40.
Port Thread: Select based on size (M5 or 1/8 series).
Rotation Angle: Specify 90, 180, or 360 degrees.
Cushion: Nil (No cushion for Size 10/15) or C (Air Cushion for Size 20/30/40).
Auto Switches: Compatible with a wide range of solid-state and reed switches (e.g., M9, A9 series).

Engineering Reminders

Kinetic Energy: Do not exceed the allowable kinetic energy values (e.g., 0.4 J for Size 40 with air cushion) as it may result in internal product failure.
External Stoppers: If high-precision rotation repeatability is required, it is recommended to use external stoppers to define the mechanical end.
Filtration: To ensure longevity, air supply should be filtered by an element of 5 μm or smaller
