Feature → Business Impact → Application: The RT/57250/M/160 uses a 50 mm bore and a 160 mm stroke to deliver precise, repeatable motion in constrained spaces, enabling compact actuator assemblies in pick-and-place and clamp applications. This translates to improved cycle times and reduced machine footprint, especially in multi-axis layouts where space is at a premium. Feature → Business Impact → Application: The Roundline design saves up to 20% space compared with basic ISO/VDMA cylinders, streamlining installations and enabling more compact control panels or machinery frames. This supports faster line reconfiguration and scalable automation in manufacturing cells. Feature → Business Impact → Application: Low-friction, long-life seals extend service intervals, lowering maintenance costs and boosting uptime for high-cycle applications such as sorting and transferring parts on assembly lines. Feature → Business Impact → Application: The magnetic piston provides straightforward integration with reed switches (for position sensing) and other sensors, simplifying control system design and bringing robust state feedback into the PLC. Feature → Business Impact → Application: Stainless steel barrel and piston rod offer corrosion resistance and durability in demanding environments, reducing wear, leakage risks, and the need for frequent replacements in wash-down or humid facilities. Feature → Business Impact → Application: Buffer cushioning minimizes impact loads at end-of-stroke, protecting delicate components and reducing shock to connected tooling, which extends actuator life and maintains precision in repetitive operations. Feature → Business Impact → Application: Port Size Rc1/4 and 1–10 bar operating range, plus -10 to 80 °C capability, provide flexible integration with standard compressed-air systems and diverse mounting options (foot, clevis, and other mountings), simplifying installation and retrofits. Feature → Business Impact → Application: Theoretical force of 1178 N supports reliable actuation for medium-load tasks, enabling robust performance in clamping, lifting, or indexing workpieces across a variety of manufacturing environments.

FAQs
For tight-space installations, select a mounting style compatible with a 50 mm bore and 160 mm stroke, such as foot, clevis, or universal rod mounts listed in the product family. Use Rc1/4 porting and Pneufit C fittings to minimize line length, and verify end-cap access for maintenance. Consider preassembling mounting brackets to speed up on-site assembly.
Confirm a 50 mm bore, 160 mm stroke, Rc1/4 port size, and 1–10 bar operating pressure. Check the temperature range (-10 to 80 °C) and the stainless steel barrel and piston rod for environmental compatibility. Ensure mounting, sensing, and end-of-stroke cushioning (buffer) are compatible with your actuated tooling.
Yes. The cylinder is designed to work with Pneufit C push-in fittings and supports several mounting configurations, including foot mounting and various rod-end options such as nut-style or clevis mounts. This versatility simplifies retrofits and consolidates supplier procurement for pneumatic subsystems.
Ideal for compact automation cells, linear actuations in clamp/transfer stations, and medium-load positioning tasks. The combination of space-saving geometry, magnetic piston feedback, and robust materials makes it a strong choice for high-cycle pick-and-place and indexing operations in automotive, packaging, and general manufacturing lines.
The low-friction seals and corrosion-resistant stainless steel components extend service intervals and reduce replacement costs. Magnetic sensing simplifies control wiring and diagnostics, while cushion damping lowers impact wear. Together, these factors decrease downtime, shorten maintenance cycles, and improve overall equipment effectiveness (OEE).
