Norgren RA/802125/M/50 ISOLine Cylinder - ISO 15552
Part Number: RA/802125/M/50
Quick Summary
Norgren RA/802125/M/50 ISOLine cylinder provides precise double-acting actuation for automation lines. In demanding manufacturing environments, downtime and wear erode throughput and predictability. This cylinder conforms to ISO 15552 and uses a magnetic design with an Adaptive Cushioning System (ACS) to minimize impact and vibration. With a 125 mm bore, 50 mm stroke, and a 1–16 bar operating range, it delivers reliable cycles across high-demand applications. It is well suited to line-side actuation, fixture clamping, and pick-and-place tasks where repeatable performance and long service life are essential for total cost of ownership and uptime.

FAQs
RA/802125/M/50 uses the ISOLine ISO 15552 standard footprint, compatible with common 125 mm bore mounting plates and standard end supports. For easy retrofits, pair with QM/8125 front or rear flange mounts and compatible D2 rear clevis options to maintain alignment and minimize assembly time.
Operating pressure ranges from 1 to 16 bar. At this range, the cylinder delivers substantial force for pushing and pulling tasks, with a theoretical 7363 N capacity at suitable conditions. Always verify system pressure and load profile to ensure consistent cycle times and actuator life.
Yes, with its ACS cushioning and durable materials, RA/802125/M/50 supports high-cycle use. Routine maintenance includes inspecting seals (polyurethane) for wear, validating switch alignment, and periodic service-kit replacement (QA/8125B/00) to sustain performance and minimize downtime.
Switch mounting brackets designed for M/50 configurations (e.g., QM/8125 series) are compatible. The product supports bracket-mounted switches, including straight plug-in cables and reed or solid-state options, enabling seamless integration with existing control systems.
Service kits for PRA/801, PRA/802, PRA/803, RA/801, RA/802, RA/803, and related RA/8000 family are listed as QA/8125B/00. For seals, cushions, and mounting accessories, consult Norgren-approved distributors or parts catalogs to ensure genuine components and compatible mounting hardware.
