This pneumatic roundline cylinder from RS PRO is a high-quality piston that uses air pressure to create a rhythmic pumping movement. It's double-acting, so the air pressure applies to each end alternately and gives it a greater stroke length than the majority of single-acting cylinders. The piston has a built-in end-of-stroke buffer that reduces wear and tear and cushions the impact of the unit. This enhances the piston's durability and prevents jolts to the system. This is a long-lasting device, even when used with non-lubricated air, meaning it's appropriate to use with oil-free air compressors.The cylinder's sturdy stainless steel material makes it a resilient choice. Thanks to its compact size, it's a good choice for use in tight spaces in a variety of industrial settings.
