Product catalog summary

Overview: The document provides comprehensive technical specifications and operational guidelines for fine lock cylinders and lock-up cylinders, specifically focusing on Series CLJ2, CLM2, CLG1, and CL1. These cylinders are designed for applications requiring precise locking mechanisms, with options for spring locking, pneumatic locking, and a combination of both.

Specifications:

Locking is possible in both directions or on either side of the cylinder stroke, with the lock-up cylinder being unidirectional.
Available bore sizes range from ø16 to ø160 mm, with standard strokes varying by series.
Locking methods include spring locking and pneumatic locking, with the ability to adjust holding power based on air pressure.

Procedures:

Ensure safety measures are in place to prevent human contact with moving parts.
Use a balance circuit to prevent piston lurching when unlocking.
Adjust air pressure to maintain load balance and prevent piston lurching.
Manual unlocking involves loosening the lock nut and adjusting the manual unlocking cam.

Precautions:

Do not apply impacts, strong vibrations, or rotational forces to the locked cylinder.
Ensure proper alignment of the load's center of gravity with the cylinder's axial center to prevent uneven wear.
Stopping accuracy is influenced by piston speed changes; maintain a constant speed for precision.

Recommendations:

Use solenoid valves with a large effective area for unlocking to improve stopping accuracy.
Place solenoid valves close to the cylinder to reduce overrun and improve accuracy.
Allow sufficient time between locked stops and unlocking to prevent lurching.

Key Data from Diagrams:

Illustrations depict the construction and operation of the locking mechanism, including the brake arm, brake spring, and manual unlocking cam.
Diagrams show pneumatic circuits for balancing pressure and preventing lurching.

Series CLJ2 Fine Lock Cylinder: This section details the Series CLJ2, a double-acting, single rod pneumatic cylinder with locking capabilities. It outlines the mechanisms of spring and pneumatic locking, component materials, and mounting options.

Locking Mechanisms: The cylinder employs two primary locking methods: spring locking (exhaust locking) and pneumatic locking (pressure locking). The spring force is amplified through a wedge effect and lever mechanism to lock the piston rod. Pneumatic pressure is used to disengage the lock.

Specifications: The cylinder is available in a bore size of 16 mm with standard strokes ranging from 15 mm to 200 mm. It operates with a maximum pressure of 1.05 MPa and a minimum of 0.08 MPa. The piston speed ranges from 50 to 500 mm/s, with a maximum speed of 750 mm/s for stationary locking.

Mounting Styles: Various mounting styles are available, including basic, axial foot, rod side flange, and double clevis styles. Each style has specific part numbers and dimensions for mounting brackets and accessories.

Component Materials: The cylinder components are made from materials such as aluminum alloy, stainless steel, carbon steel, and special friction materials, with various treatments like anodizing and plating for durability.

Auto Switch Options: The document lists compatible auto switch models, detailing their wiring, load voltage, and special functions. It also provides guidelines for mounting positions and heights for these switches.

Performance and Safety: The document emphasizes the importance of not exceeding the holding force to prevent damage to the brake shoe. It provides formulas for calculating kinetic energy and guidelines for operating within safe limits.

Additional Information: Detailed tables and diagrams are included to illustrate component parts, dimensions, and recommended pneumatic circuits. The document also provides cautionary notes on handling and specific conditions for optimal performance.

Series CL1 Lock-up Cylinder: This section provides detailed specifications and guidelines for the Series CL1 Lock-up Cylinder, a double-acting, single rod cylinder. It includes information on specifications, mounting instructions, operating conditions, and maintenance procedures.

Specifications:

Operating Pressure: Minimum 0.05 MPa, Maximum 0.2 MPa.
Temperature Range: Without auto switch: -10 to 70°C; With auto switch: -10 to 60°C.
Piston Speed: Maximum 200 mm/s during locking, up to 500 mm/s for stationary locking.
Lock-up Direction: Unidirectional, but can be changed.

Mounting and Installation:

Refer to pages 650-656 for auto switch mounting details.
Ensure proper alignment and torque when installing tie-rods.
Use appropriate mounting brackets and accessories for different bore sizes.

Operating Conditions:

Ensure no rotational force is applied to the piston rod.
Maintain axial load direction to prevent chatter or twist.
Use a guide to control load movement.

Maintenance and Handling:

Regularly check for loose nuts and retighten if necessary.
Perform flushing before connecting piping to remove debris.
Use non-lube style lubrication; additional lubrication is not necessary.

Lock-up Mechanism:

Manual lock release is available for bore sizes ø40 to ø100.
Lock-up is achieved through air pressure and mechanical components.
Ensure proper air pressure (0.2 MPa to 0.3 MPa) during installation and adjustment.

Component Materials:

Various components are made from aluminum alloy, carbon steel, and other durable materials.
Replacement parts and seal kits are available for maintenance.

Additional Notes:

Refer to specific product precautions for selecting cylinders.
Ensure compliance with recommended pneumatic circuits to prevent operational issues.
