Question by: Shane W on Apr 15, 2026, 6:58 AM
Need a cylinder that’ll pull back under power too, not just spring return. Is this RR-308 double-acting?
Answer by: Customer Support on Apr 16, 2026, 12:27 PM
With the RR-Series, hydraulic pressure is used to control both the advance and the retract, so you get powered return and more precise control of plunger speed in both directions.
Question by: Jean O on Nov 1, 2025, 1:10 PM
Got a job that needs some back-and-forth cycling on a press fixture, does this cylinder actually retract under hydraulic power or does it spring back?
Answer by: Customer Support on Nov 3, 2025, 7:46 AM
Full hydraulic control on both directions. The RR-308 is double-acting, meaning hydraulic pressure drives the plunger out and pulls it back in. That gives you precise speed control on the retract stroke, which matters a lot when you're running repeated cycles on a press or fixture setup. Spring-return cylinders can't match that kind of control, especially over a longer run of cycles.
