Short stroke cylinders W series mm The wide product range and unique design make Univer Short stroke cylinders W series essential for all applications where compact overall dimensions and short strokes are required. This product, thanks to its versatility, the vast variety of accessories, the various bore sizes combined with mechanical shock-absorbers, complies perfectly with the requirements of the industry. Operating pressure: 1, bar Ambient temperature: - C Fluid: Filtered air, with or without lubrication Construction details Barrel profile of extruded aluminium alloy, internally and externally anodized ( - µ). Removable end-caps for easy inspection. Piston fitted with permanent plastoferrite ring (upon request; bore sizes ) Piston seals produced in a special nitrile compound selfcompensate against wear. Rolled stainless steel rod (AISI 33) with female thread (male thread upon request). Self-lubricating guide bearings.
