Robust Locking for Enhanced Safety

The MCBQI2 rod locking cylinder offers reliable spring locking that automatically engages when air pressure is lost, ensuring operator and equipment safety. With a locking force of 290 N for a 32 mm bore and consistent performance across standard bore sizes, it is engineered for critical stop-hold functions in industrial automation.

Versatile Installation & Performance

Available in multiple mounting configurationsbasic, foot, flange, and double clevisthe MCBQI2 adapts seamlessly to varied machine designs. Its double acting rod and rubber bumpers at both ends minimize noise and wear, while its tie-rod construction enhances longevity. Lubricated or non-lubricated compressed air can be used as the operating medium for flexibility and maintenance ease.

FAQs of Rod Locking Cylinders Model: MCBQI2:

Q: How does the rod locking mechanism in the MCBQI2 cylinder function?

A: The MCBQI2 uses a spring-actuated lock that engages automatically to hold the piston rod in position when air pressure drops or is interrupted. To release the lock, air pressure (minimum 0.3 MPa) must be applied, providing reliable holding and quick release for enhanced machine safety and control.

Q: What are the recommended applications for the MCBQI2 rod locking cylinder?

A: This cylinder is ideal for situations where stopping and holding the load in a precise position is critical, such as in material handling, automated assembly lines, or machinery safety interlocks. Its strong locking force and high repeatability make it particularly suitable for equipment requiring precise, secure actuation.

Q: When should the lock release pressure be applied in operation?

A: Air pressure of at least 0.3 MPa should be supplied to the lock release port whenever movement of the rod is required. This disengages the spring lock, allowing the cylinder to operate as a standard double-acting actuator until locking is needed again.

Q: Where can the MCBQI2 rod locking cylinder be installed?

A: Thanks to its range of mounting stylesbasic, foot, flange, and double clevisthe MCBQI2 can be integrated into various machines and equipment across industries. Its compact form and versatile installation enable it to fit most automation setups and replacement scenarios.

Q: What maintenance is necessary for optimal performance?

A: To ensure longevity and reliable function, use filtered compressed air (lubricated or non-lubricated). Regularly inspect the NBR seals for wear, and replace them as needed. Periodically check for accumulated dust in the air lines to avoid contamination and maintain sealing effectiveness.

Q: How does the cylinder provide precise positioning and repeatability?

A: Engineered with a sturdy tie-rod design and incorporating high-quality NBR seals, the MCBQI2 achieves a repeatability of 0.2 mm. Combined with its effective locking mechanism and robust build, this enables controlled, repeatable operations even in demanding environments.

Q: What are the main benefits of using the MCBQI2 rod locking cylinder?

A: The cylinder enhances safety by securely locking loads in power-off scenarios, increases operational flexibility with diverse mounting options, and adapts seamlessly to various working conditions. Its lightweight yet strong construction and reliable sealing reduce maintenance while boosting productivity in automation and manufacturing systems.
