SMC CXS/CXSJ Dual Rod Cylinder

The SMC CXS and CXSJ series are dual rod cylinders designed for precise, non-rotating linear motion, ideal for pick-and-place applications and light-duty material handling. Below is a detailed overview of their specifications and features based on available information:

CXS Series (Basic Type)

• Description: The CXS series is a dual rod cylinder with a guide function, suitable for applications requiring high non-rotating accuracy and stability.
• Key Features:
  • Bore Sizes: 6, 10, 16, 20, 25, and 32 mm.
  • Stroke Lengths: Up to 100 mm (standard strokes: 10, 20, 30, 40, 50, 75, 100 mm).
  • Bearing Types: Available with slide bearings (CXSJM) for lateral stability against side loads or ball bushing bearings (CXSJL) for smoother operation and stable travel resistance.
  • Non-Rotating Accuracy: ±0.1°.
  • Mounting: Can be mounted from three directions, with workpieces attachable on three surfaces.
  • Auto Switches: Compatible with reed or solid-state switches, viewable from four directions.
  • Air Cushion: Minimal addition to overall length for shock absorption.
  • Clean Room Versions: Available with specifications like 10- (relief type), 11- (vacuum suction type), 12- (relief type with specially treated sliding parts), and 21-/22- (copper, fluorine, and silicon-free with low particle generation).
• Applications: Accurate pick-and-place, light-duty material handling.
• Additional Notes: Detailed drawings available in manufacturer catalogs (e.g., pp. 755-757 for CXS series).

CXSJ Series (Compact Type)

• Description: The CXSJ series is a more compact and lighter version of the CXS, designed for space-constrained applications while maintaining high precision.
• Key Features:
  • Bore Sizes: 6, 10, 15, 20, 25, and 32 mm (CXSJ compact type available in 6 and 10 mm bores for certain configurations).
  • Stroke Lengths: Up to 100 mm (standard strokes: 10, 20, 30, 40, 50, 75, 100 mm; up to 50 mm for 6 and 10 mm bores in some cases).
  • Bearing Types: Slide bearing (CXSJM) or ball bushing bearing (CXSJL).
  • Non-Rotating Accuracy: ±0.1°.
  • Thrust: Twice the thrust of a standard cylinder due to dual rod design.
  • Stroke Adjustment: Adjustable stroke range of 0 to -5 mm.
  • Mounting: Can be mounted from three directions, with workpieces attachable on three surfaces.
  • Auto Switches: Available, viewable from four directions. Axial piping option for 6 and 10 mm bores.
  • Lube-Retainer Option: Enhances durability in micro-powder environments by forming a grease film on the piston rod, reducing dust and foreign matter entry (4x durability compared to standard models).
  • Made to Order: Custom configurations available.
• Applications: Pick-and-place, compact automation setups, environments requiring dust resistance.
• Additional Notes:
  • More compact body compared to CXS series.
  • CAD data may not be available for all model numbers; contact SMC for specific part numbers

Key Differences

• Size and Weight: CXSJ is more compact and lighter than CXS, making it suitable for applications with space constraints.
• Bore and Stroke Options: CXS offers clean room versions across all bore sizes (6–32 mm), while CXSJ’s clean room versions are limited to 6 and 10 mm bores for certain configurations.
• Lube-Retainer: CXSJ offers a lube-retainer option for enhanced durability in dusty environments, not mentioned for CXS.
• Piping: CXSJ supports axial piping for 6 and 10 mm bores, which is not specified for CXS.

Features & Advantages

• Anti-rotation: Dual rods prevent piston rotation—great for handling and pick-and-place.

• Compact design: Ideal for tight spaces (especially CXSJ).

• High repeatability: Linear guides offer smooth and precise motion.

• Optional air cushion: For smoother deceleration and shock absorption (CXS only).

• Mounting flexibility: Side, bottom, or end-face mounting.
