Product Overview

     The SOLH CY3 series is an upgraded magnetic coupling rodless cylinder based on the classic SMC CY1 series, divided into two mainstream models: CY3B basic type without mounting surface and CY3R direct mounting type. It adopts a fully enclosed magnetic non-contact transmission structure, realizing synchronous movement of the internal piston and external slide table through strong magnetic coupling. Featuring zero leakage, dust-free and pollution-free operation, ultra-long stroke and compact installation, it is widely applicable to clean-grade, light-to-medium load, long-distance linear driving scenarios. With a bore range from φ6 to φ63mm and a maximum stroke of 5000mm, it saves 50% installation space compared with traditional tie-rod cylinders and serves as the preferred clean long-stroke driving solution for high-standard automated production lines.

Core Positioning & Structural Features

• Magnetic Coupling Transmission & Zero Leakage Clean Operation: The piston and slide table adopt magnetic synchronous driving with fully enclosed cylinder barrel design. No piston rod extends outward, achieving complete air tightness, zero leakage and zero dust pollution. It perfectly matches strict production environments such as food processing, medical equipment and semiconductor electronics.

• CY1 Upgraded Version with Enhanced Durability: Compared with the traditional CY1 series, the wear-resistant ring length is increased by 70%, effectively improving bearing capacity and sliding stability. The built-in lubrication retainer of the dustproof ring forms a lasting protective lubricating film, reducing the minimum working pressure to 0.12MPa and greatly extending service life. Except for φ6 specification, all other models retain the same mounting dimensions as CY1 for direct replacement and upgrade.

• CY3B Basic Type Minimalist Structure: The smooth cylinder barrel has no reserved mounting surface and requires two-end support brackets for fixation. The slide table is not equipped with built-in guiding structure, so external linear guides or guide rods are mandatory to prevent eccentric load and magnetic decoupling failure.

• Standard Rubber Buffer & High-Speed Optional Specification: Built-in dual-end rubber buffers absorb operating impact and reduce running noise for stable conventional cyclic operation. Optional X160 high-speed specification supports a maximum operating speed of 1500mm/s to adapt to high-frequency fast-moving working conditions.

• Convenient Magnetic Switch Installation: Pre-reserved switch grooves on both sides of the cylinder body are compatible with D-M9 series magnetic switches, realizing flexible and accurate real-time position feedback for stroke positioning.

Core Configuration & Selection Guidelines

1 Bore Size Selection by Load & Thrust

• φ6~φ15 (Micro Light Duty): Suitable for loads ≤2.5kg, dedicated to short-stroke precision transfer of mini components in electronic and medical equipment.

• φ20~φ32 (General Light Duty): Matched with 4~10kg light load, ideal for conventional long-stroke pushing and pulling (≤1000mm) in general automated production lines.

• φ40~φ63 (Medium Duty): Applicable for 16~40kg medium load scenarios, perfect for heavy long-stroke handling and high-frequency cyclic operation in food and packaging industries.

2 Stroke & Guiding System Selection

• Stroke Range: Standard stroke covers 50~1000mm; extended ultra-long stroke up to 5000mm for special long-distance driving demands.

• Mandatory External Guiding Design: The CY3B basic type has no built-in guiding structure. External linear slide rails or guide rods must be equipped to support the load and prevent magnetic decoupling caused by eccentric force deviation.

• Standard Fixing Method: Fixed by optional two-end support brackets with suspended cylinder body and zero contact friction, ensuring stable magnetic coupling operation.

3 Environment & Functional Configuration Selection

• Priority for Clean Environments: Zero-leakage and pollution-free design adapts to strict dust-free and sterile working conditions in food, medical and electronic semiconductor industries.

• High-Speed Working Condition Upgrade: Select optional X160 high-speed specification (max 1500mm/s), equipped with external hydraulic buffers to eliminate high-speed impact and ensure stable operation.

• Precision Position Feedback: Equip with D-M9 series magnetic switches to realize two-point or multi-point accurate stroke positioning and signal feedback.

Typical Industrial Application Scenarios

• Clean Room Material Transfer: Zero-leakage and dust-free magnetic coupling structure is ideal for long-distance material handling in electronic, semiconductor and medical dust-free workshops without contaminating clean environments.

• Food & Beverage Packaging Lines: Rust-proof stainless steel cylinder barrel with easy-to-clean surface adapts to hygienic production standards, suitable for long-stroke displacement of light and medium-duty workpieces in food processing equipment.

• Equipment Door & Cover Driving: No rod extension design saves external space, perfectly applied to compact long-stroke opening and closing driving of automated equipment protective doors and shielding covers.

• Long-Stroke Precision Positioning Platform: Cooperates with external high-precision guiding rails to achieve stable repeated positioning accuracy, suitable for 1~2m long-distance precise positioning and cyclic conveying of assembly lines.

• Space-Saving Replacement for Tie-Rod Cylinders: Solves the space occupation problem of traditional tie-rod cylinders in long-stroke (>500mm) scenarios, reducing overall equipment installation space by 50% for compact equipment design.

Three-Step Quick Selection Guide

1. Bore Size Confirmation: Calculate required thrust based on load weight with a safety factor ≥2. Recommended rules: ≤2.5kg → φ15; 4~10kg → φ32; 16~40kg → φ63.

2. Stroke Specification Confirmation: Select standard 50~1000mm stroke for conventional demands; choose extended specification for ultra-long stroke up to 5000mm.

3. Functional Configuration Matching: Priority selection for clean pollution-free working conditions; upgrade to X160 high-speed spec + hydraulic buffer for fast operation; add D-M9 series magnetic switches for real-time position detection.
