Category buying guide

Use thin cylinders when axial space is the limiting factor.

Thin and compact cylinder selection should focus on available body length, lightweight structure, mounting face, compact profile, bore, stroke, port direction, guide options, magnetic piston needs, and replacement dimensions.

Choose by motion job

Start with the motion the actuator must make.

Pick the closest actuator use case, then confirm bore, stroke, load, mounting, pressure, speed, and space constraints before RFQ.

Category FAQ

Common questions before sending an inquiry.

01Thin and Compact Pneumatic CylindersAre thin cylinders the same as compact cylinders?

They are often used similarly. Thin or compact cylinders focus on shorter body length for tight installations, with series differences in body shape, mounting, and standard dimensions.

02Thin and Compact Pneumatic CylindersCan a thin cylinder handle side load?

A basic thin cylinder should avoid side load. If side load is present, consider a guided compact cylinder or external guide support.

03Thin and Compact Pneumatic CylindersWhat is important for replacing an SDA or CQ2-style cylinder?

Bore, stroke, body dimensions, mounting holes, port position, sensor groove, and rod-end details are the key details.
