FAQs
QM/31/320/22 is designed to mount a 320 mm bore Lintra Plus cylinder with standard bracket interfaces. It supports common mounting patterns used in Norgren actuator assemblies, enabling straightforward alignment of limit switches and sensors. For compatibility, verify bore sizing and mounting hole spacing against your cylinder model and ensure correct fixture hardware per Lintra Plus guidelines.
The bracket provides a rigid interface to preserve switch alignment relative to the piston rod, reducing positional drift during cycling. Typical tolerances focus on perpendicularity and axial alignment to preserve switch actuation accuracy. In practice, verify flat mounting surfaces, clean fastener threads, and secure clamping to prevent vibration-induced misreads in high-cycle environments.
Yes. The Lintra Plus series is designed for reliable, repeatable mounting in demanding industrial settings. Its 320 mm bore compatibility supports frequent switch actuation in packaging and assembly lines, while the bracket’s robust construction helps minimize downtime due to misalignment, wear, or fastener loosening. For maximum life, pair with proper torque specs and regular inspection schedules.
Key considerations include CE marking for EU compliance and appropriate IP ratings based on environmental exposure. While your application may require RoHS compliance and fire-safety standards, verify each bracket configuration against your facility’s safety and quality requirements. When sourcing, request documentation confirming conformity with relevant industrial standards and any customer-specific certifications.
The bracket standardizes mounting across lines, reduces assembly time, and minimizes misalignment-related downtime, contributing to lower maintenance labor costs and higher line availability. Over multiple production cycles, predictable performance and common spare parts translate to faster issue resolution, fewer emergency fixes, and a favorable return on investment for automation projects.
