Product catalog summary

Overview: The document details the technical specifications and features of the Compact Cylinder with Lock, Series CLQ, designed to maintain cylinder position when supply pressure drops or residual pressure is released. It is suitable for bore sizes ranging from ø20 to ø100 mm.

Key Features:

Locking Mechanism: Allows locking at any position within the stroke, preventing drops during mid-stroke emergency stops and accommodating external stopper positions.
Locking Directions: Options for extension and retraction locking, selectable upon order.
Compact Design: The lock unit is integrated within the cylinder's dimensions for a low profile.
Manual Unlocking: Facilitates easy manual unlocking for operational flexibility.

Specifications:

Bore Sizes: ø20, ø25, ø32, ø40, ø50, ø63, ø80, ø100 mm.
Operating Pressure: Maximum 1.0 MPa, minimum 0.2 MPa.
Temperature Range: -10 to 70°C without auto switch, -10 to 60°C with auto switch.
Locking Pressure: 0.05 MPa or less for locking, 0.2 MPa or more for unlocking.

Mounting Options:

Types: Through holes, double end taps, foot type, front flange type, rear flange type, double clevis type.
Auto Switch: Available with or without, with various mounting options and lead wire lengths.

Construction Details:

Materials: Made from aluminum alloy, carbon steel, stainless steel, and other durable materials.
Locking System: Utilizes a lock ring and brake spring mechanism for secure locking.

Applications: Ideal for applications requiring reliable position holding, such as press fitting jigs and lifters, ensuring safety and precision in industrial operations.

Procedures: Includes instructions for mounting auto switches on compact cylinders, specifying the use of mounting screws and spacers, and guidelines for proper torque application. Describes connecting auto switches to PLCs with wiring diagrams for NPN and PNP configurations.

Standards and Safety: References ISO 4414 and JIS B 8370 standards for pneumatic equipment. Emphasizes trained personnel handling, machinery lockout before maintenance, and verifying equipment operation post-installation. Warns against operating beyond specified conditions and highlights protective measures to prevent injury.

Recommendations: Align rod axis with load to prevent twisting, use speed controllers to adjust cylinder drive speed, and apply grease to prevent seizure of rotating parts. Avoid scratching or damaging components to prevent air leakage and malfunction.

Key Data from Tables: Provides detailed measurements for joint and mounting brackets, specifying part numbers, applicable bore sizes, and dimensions like weight, eccentricity tolerance, and backlash. Lists auto switch types and their applicable bore sizes, along with proper mounting positions and heights for stroke end detection.

Specifications and Design Considerations:

Impact Absorption: For high-speed or heavy load operations, consider installing a deceleration circuit or an external shock absorber.
Pressure Drop: Install safety equipment to prevent damage or injury from pressure drops.
Power Loss: Implement measures to protect against injury and equipment damage in case of power loss.
Sudden Lurching Prevention: Design circuits to prevent sudden lurching of driven objects.
Emergency Stops: Ensure machinery design prevents injury or damage during emergency stops.
Restart After Stops: Design machinery to prevent injury or damage upon restart after an emergency stop.

Mounting and Operating Environment:

Corrosion and Dust: Avoid using in corrosive environments. Protect equipment in dusty or splash-prone areas.
Magnetic Fields: Avoid operating auto switches in strong magnetic fields.

Maintenance and Piping:

Regular Maintenance: Follow the instruction manual to prevent malfunction and damage.
Compressed Air Handling: Ensure proper removal of equipment and exhaust of compressed air before maintenance.
Drain Flushing: Regularly remove drainage from air filters.
Pipe Preparation: Thoroughly clean pipes before connection to prevent debris entry.

Air Supply and Lubrication:

Air Quality: Use clean air and install air filters, after-coolers, or water separators to prevent equipment malfunction.
Temperature Range: Operate within specified fluid and ambient temperature ranges to prevent freezing and damage.

Auto Switch Precautions:

Specifications Compliance: Use products within specified load current, voltage, temperature, and impact ranges.
Magnetic Interference: Maintain a minimum separation of 40mm between auto switch cylinders to prevent malfunction.
Wiring Considerations: Keep wiring short to prevent excess current and ensure proper insulation.
Surge Voltage: Use protection boxes for loads generating surge voltage.
Interlock Circuits: Implement double interlock systems for high reliability.

General Warnings:

Explosive Atmospheres: Do not use auto switches in explosive gas environments.
Magnetic Fields: Avoid areas with strong magnetic fields to prevent malfunction.
Water Exposure: Avoid continuous water exposure to prevent malfunction.

Operating Environment Precautions:

Avoid using auto switches in environments with oil, chemicals, or temperature cycles. Consult SMC for guidance in such conditions to prevent insulation issues or malfunction.
Reed switches should not be exposed to excessive impact shock (300m/s² or more) as it may cause malfunction.
Solid state switches should be kept away from surge-generating units to prevent damage.
Prevent accumulation of iron waste or proximity to magnetic substances to avoid loss of magnetic force.

Maintenance Guidelines:

Regularly tighten switch mounting screws and check for lead wire damage to prevent malfunction.
Ensure the green LED on the 2-color indicator type switch is lit when stopped at the correct position.

Pneumatic Circuit Selection:

Do not use for intermediate cylinder stops as it may shorten service life.
Select the correct locking direction; the cylinder does not generate holding force opposite to the locking direction.
Ensure load weight, maximum speed, and eccentric distance are within specified limits to avoid damage.

Manual Unlocking Procedures:

For sizes ø20 to ø32, manual unlocking involves removing the dust cover and using a flat head screwdriver or unlocking bolt.
Ensure no external force is applied during unlocking to prevent sudden movement.

Maintenance and Safety:

Operate with clean, unlubricated air to maintain performance.
Do not apply grease to the piston rod or disassemble the lock unit to avoid reducing locking performance.
