Norgren QM/8040/38 Piston Rod Swivel Mounting - 40 mm bore
Part Number: QM/8040/38
Quick Summary
Piston Rod Swivel Mounting from Norgren QM/8040/38 delivers precise, robust actuation for pneumatic cylinders in automation systems. Engineers often contend with misalignment and wear at rod connections, leading to degraded accuracy and increased maintenance. Certifications to verify include CE compliance for EU safety directives, IP ratings for environmental protection, and SIL compatibility where safety functions are integrated; check the datasheet for specifics. In practice, this mounting improves alignment and reduces side loads, supporting longer service life. By pairing this solution with compatible Norgren cylinders, manufacturers can streamline installation, extend maintenance intervals, and lower total cost of ownership. This accessory fits compact spaces and contributes to reliable line performance across factory floors and automated processes.

FAQs
Installation is straightforward on compatible 40 mm bore cylinders. Begin by aligning the swivel mounting to the piston rod, secure with the correct fasteners, and ensure freedom of movement without binding. Use the CAD data from Norgren to confirm hole spacing and orientation, then test for smooth articulation under load.
By allowing swiveling at the rod end, the mount reduces side loads and misalignment, improving sealing life and repeatability. The 40 mm bore compatibility ensures consistent piston alignment, while the compact 77 mm length minimizes added inertia. In practice, you’ll see longer service intervals and steadier actuator performance in automation lines.
Yes, the QM/8040/38 is designed for reliable operation in demanding environments. Its 0.2 kg weight keeps inertia manageable, and German engineering emphasizes tight tolerances and durability. When used with compatible Norgren cylinders, it supports high-cycle cycles with predictable lifespans, reducing unplanned downtime and improving line throughput. Engineers may also leverage the CAD downloads to optimize mounting orientation.
Certification details must be confirmed in the datasheet. Typical considerations include CE compliance for EU safety directives and IP ratings for environmental protection. Some configurations support SIL-rated systems where safety is critical. Always verify current certifications through the datasheet or contact Norgren to ensure compliance for your installation and regulatory requirements in your region and industry standards.
The swivel mounting reduces misalignment-induced wear, extending seal life and reducing maintenance frequency. Coupled with CAD data and a compact footprint, it lowers install time and spare parts costs. Over multiple production cycles, the uptime gains from fewer rod-end failures translate to noticeable total cost of ownership improvements for modern automated facilities seeking predictable budgets.
