FAQs
Installation begins with ensuring a 50 mm bore and 30 mm stroke meet your space and load requirements. Use standard G1/8 fittings and compatible mounting brackets, connect to an air supply within 2–10 bar, and align the actuator for straight-line travel. Because this is a single-acting cylinder with no internal cushioning, confirm end-of-stroke speed and mounting clearance to avoid impact; external dampening can be added if needed.
The actuator provides a theoretical force of 1094 N at typical operating pressures up to 10 bar, with a 50 mm bore and 30 mm stroke. The magnetic piston enables straightforward sensing, simplifying control loops in PLC-based systems. Its single-acting design is ideal for push or pull motions driven by air pressure, while the absence of internal cushioning requires careful end-of-stroke management.
Yes, for moderate to high-cycle packaging lines where compact footprint and reliable sensing are valuable. The non-corrodible materials and low-friction seals minimize maintenance downtime, while the magnetic piston supports reliable position feedback. For very high-speed or dampened end-stroke requirements, consider external cushioning or an alternative model with built-in dampening.
Certification details are not listed in the provided product data. Prospective buyers should consult the official Norgren datasheet or contact support to confirm CE, IP, or other regulatory ratings. This ensures the cylinder meets regional safety standards and industry-specific requirements before deployment in automation environments.
The combination of a corrosion-resistant anodised barrel, martensitic stainless steel rod, and a low-friction seal design reduces wear and maintenance intervals, delivering lower lifecycle costs. The compact length saves space and simplifies installation, contributing to higher machine uptime and improved return on investment in automated lines that prioritize reliability and footprint efficiency.
