SMC CUJB8-10S Pneumatic Compact Cylinder (CUJB810S)
1. Product Overview
The SMC CUJB8-10S, also identified by the model code CUJB810S, is a miniature single-acting compact cylinder belonging to SMC’s CUJ series of ultra-small pneumatic actuators. Engineered for light-duty automation tasks with strict space constraints, it features an 8 mm bore diameter and 10 mm stroke length, delivering precise linear motion driven by compressed air for extension and a built-in spring for retraction. This cylinder is optimized for applications such as micro-component handling, vacuum suction cup actuation, and precision positioning in electronic manufacturing, semiconductor processing, and laboratory automation equipment. Its lightweight, compact structure and compatibility with low-pressure pneumatic systems ensure seamless integration into small-scale automation setups, while adhering to SMC’s high standards for reliability and durability in clean industrial environments.
2. Main Functions
| Function | Detailed Description |
|---|---|
| Single-Acting Linear Actuation | Achieves extension via compressed air input and automatic retraction using an internal return spring, simplifying pneumatic circuit design and reducing air consumption for single-direction tasks. |
| Micro-Precision Positioning | Ultra-short 10 mm stroke and rigid internal structure ensure high repeatability accuracy, meeting the positioning requirements of delicate component assembly and handling. |
| Impact Buffer Protection | Integrated rubber buffers at the stroke end absorb kinetic energy during retraction, minimizing operational noise and preventing damage to fragile workpieces and cylinder internal components. |
| Vacuum System Compatibility | Designed for seamless connection with vacuum suction cups and mini vacuum generators, providing synchronized lifting and lowering motion for small part transfer in vacuum automation lines. |
| Space-Saving Installation | Standardized mounting holes and ultra-compact profile enable direct installation on small fixtures, robotic end-effectors, and compact automation modules without additional adapters. |
3. Technical Features
- Ultra-Miniature Design: With a total volume of less than 12 cm³, the cylinder occupies minimal installation space, making it ideal for densely packed automation systems and micro-manipulation equipment.
- Corrosion-Resistant Materials: The cylinder barrel is crafted from high-strength aluminum alloy, while the piston rod uses SUS304 stainless steel, ensuring excellent resistance to moisture and chemical corrosion in clean industrial environments.
- High-Efficiency Sealing System: Premium NBR rubber seals maintain airtightness and prevent internal air leakage, ensuring stable performance even at the minimum operating pressure of 0.15 MPa.
- Broad Operating Range: Functions reliably within an air pressure range of 0.15–0.7 MPa and an ambient temperature range of -10°C to 60°C, adapting to typical working conditions in electronics and semiconductor factories.
- Low Energy Consumption: Optimized internal airflow path reduces air demand during operation, lowering overall energy costs for continuous-cycle automation applications.
- RoHS Compliance: Meets international environmental standards, free of restricted hazardous substances, and suitable for use in eco-friendly production lines.
