125 mm bore and 400 mm stroke provide substantial downward and push force in a compact footprint, delivering 7363 N of theoretical force for high-duty cycle applications. This enables reliable material handling, clamping, and part transfer with fewer cycles lost to stalling or drift. The Adaptive Cushioning System (ACS) dampens end-of-stroke impact, reducing shock loads, extending seal life, and lowering maintenance costs in high-speed pick-and-place lines. A magnetic piston supports straightforward, bracket-mounted sensing, simplifying switch integration and enabling precise position feedback without additional hardware. The anodised aluminium barrel and martensitic stainless steel piston rod offer corrosion resistance and durability in harsh workshop environments, while a G1/2 port size and ISO 15552 compatibility ensure quick manifold and valve integration. The 125 mm bore, 400 mm stroke, and 489 mm overall length (142 mm width, 142 mm height) provide a stable, repeatable motion profile even in tight spaces. A broad range of mountings (rear clevis, front/rear flange, swivel bearings, and more) and fittings from Pneufit C families facilitate straightforward installation and scalable configurations. The unit’s 9.2 kg weight reflects robust construction designed for long service life in demanding automation tasks, with a German engineering heritage underpinning reliable, repeatable performance across multiple lines.

FAQs

RA/802125/M/400 supports a broad range of ISOLine mountings, including D2 rear clevis, narrow and wide hinge styles, swivel bearings, front/rear flange mounts, and Piston Rod clevis options. This compatibility enables quick installation on existing frames and simplifies retrofits. When selecting a mounting, consider stroke travel, load distribution, and operator reach to minimize side loads and maintain alignment across cycles.
Key specifications include a 125 mm bore, 400 mm stroke, 1 to 16 bar operating pressure, and -20 to 80 °C operating temperature. The port size is G1/2, medium is compressed air, and the cylinder is double-acting with Adaptive Cushioning System for end-of-stroke control. Theoretical force is 7363 N, and overall dimensions are 489 mm length by 142 mm width and 142 mm height, with 9.2 kg weight.
Yes. The combination of ACS cushioning, magnetic sensing capabilities, and a robust aluminium barrel with stainless steel rod provides high-cycle reliability, consistent repeatability, and reduced maintenance. The ISO 15552 standard ensures interchangeability with other brands, helping to minimize downtime during replacements and expansions. Proper mounting and air quality control further extend service life in high-speed lines.
Service kits compatible with the RA/802125/M/400 range are available under group QA/8125B/00, including kits for PRA/801, PRA/802, PRA/803, RA/801, RA/802, RA/803, RA/181, RA/182, RA/8000, and RA/8020 variants. Regular checks should target seal wear, cushion performance, and sensor alignment. Access to CAD, brochures, and datasheets via provided downloads supports proactive maintenance planning.
