CG3 Series Ultra-Short Lightweight Cylinder | New-Generation Compact High-Speed Pneumatic Cylinder

Brand: SOLH by Richge Technology 

1. Product Overview & Core Structural Features

     The SOLH CG3/CDG3 series is a new-generation ultra-short aluminum alloy lightweight pneumatic cylinder, serving as a direct upgrade and replacement for the traditional CG1 series. It covers a wide bore range from φ20 to φ100mm, with a maximum overall length reduction of 51mm and 24% weight reduction compared with CG1. Featuring ultra-compact body, ultra-light weight, high-speed low-noise operation and oil-free maintenance-free design, it is perfectly suited for medium & light-load, long-stroke, high-frequency operating and space-limited scenarios, widely applied in automated production lines, electronic equipment, packaging machinery and light industrial automation systems.

  1.1 Industry Standard & Strong Interchangeability

     Developed based on the new-generation SMC short-type round cylinder standard, the CG3 series boasts excellent mounting interchangeability with the old CG1 series while achieving more compact overall dimensions, effectively upgrading old equipment and optimizing mechanical space layout without complicated structural modification.

  1.2 Premium Lightweight Material Structure

     Adopting high-strength aluminum alloy for cylinder tube and end covers, paired with hard-chromed piston rod. The optimized material formula reduces overall weight by 24% compared with CG1, featuring high structural strength, excellent heat dissipation and strong deformation resistance, ensuring stable long-term high-frequency operation.

  1.3 Integrated Compact Structure & Flexible Piping

     Integrated cylinder tube and end cover structure with thread locking design simplifies disassembly, assembly and daily maintenance. The innovative 4-way piping layout (90° interval) provides ultra-high freedom for installation and piping, solving the installation bottleneck of narrow equipment space and supporting diversified mechanical layout schemes.

  1.4 Diversified Motion Types for Full Scenario Coverage

     • Double Acting (CG3B): Dual-end air intake reciprocating motion, the most universal standard type for conventional automated linear driving.

     • Single Acting (CG3S/T): S = Spring return, T = Spring extend; automatic reset after power failure for safety interlock and emergency reset scenarios.

     • Double Rod (CG3W): Dual-end rod synchronous movement, doubled effective stroke and excellent torsion resistance for special linkage and positioning mechanisms.

     • Non-Rotating Rod (CG3K): Hexagonal anti-torsion piston rod, zero rotation during operation to guarantee high-precision repeated positioning.

  1.5 Optimized Buffer & High-End Sealing System

     Standard high-elasticity rubber buffer (N) for basic shock absorption and noise reduction; optional A-type air buffer for high-speed frequent operation to eliminate end impact and extend service life. Equipped with low-friction composite sealing ring and built-in oil storage groove, the cylinder features ultra-low starting pressure, stable operation and oil-free maintenance performance, with a service life of over 8 million cycles.

  1.6 Intelligent Induction Configuration

     CDG3 model comes with built-in magnetic ring, compatible with M9B/A93/Z73 series magnetic switches for real-time piston position detection and PLC automatic signal linkage control; CG3 non-magnetic version is applicable for simple cyclic motion without position detection requirements.

6. CG3 vs CG1 Selection Comparison

7. 3-Step Quick Selection Guide

     1. Bore Selection: Select the appropriate bore size according to the actual load weight, reserve no less than 50% safety margin. Prioritize CG3 series for light-load and space-constrained working conditions.

     2. Stroke Selection: Set actual working stroke plus 10~20mm safety margin. Follow standard stroke rules: double acting ≤300mm, single acting ≤100mm.

     3. Functional Configuration: Choose B for conventional double acting reciprocating motion; S for single acting spring reset safety scenarios; K for high-precision anti-torsion positioning. Select A-type air buffer for high-speed operation (>500mm/s) to reduce impact and noise. Choose CDG3 magnetic model matched with M9B/A93 switches for real-time position detection and automatic control.
