Compact Air Products produce cylinders from 3/4" to 8" bore that feature a high precision machined and workhardened bore in a high-grade anodized aluminum frame (housing). Low friction and high concentricity is the result of machining the bore and contributes to long life and millions of cycles when properly applied without side load. When side load and high impact are involved, see our Husky®, Heavy Duty options.
