Construction Details Over 3 decades of experience and close attention to detail at design, production and assembly produce the ultimate Fabco-Air Square 1® Cylinders. They FIT, not only into very tight spaces, but into ANY cylinder application. They WILL fit YOUR application. 1 The square body material is a custom aluminum extrusion with a relief extruded in to provide mounting rails. The SQL series extrusion includes the body side extensions for the Side Lug Mounting. These mounting rails are machined flat before any other machining is done. This step eliminates any twist or curl in the rails,...

Square 1® CylindersMale Rod Thread Option Single Rod -MR Double Rod, Rod End Only -MR Double Rod, Both Ends -MR2 A high strength stud is threaded into the standard female rod end and retained with Loctite®. This method eliminates the small diameter thread relief area normally required when machining male threads. It provides a much stronger rod end which can be repaired, rather than replacing the complete rod, should the thread be damaged. Viton Seals Option -V For elevated temperatures (-15°F to +400°F) or compatibility with exotic media. Consult engineering for compatibility information....

Option Specifications Option Specifications Standard piston rod and rod bushing on both ends of the cylinder. Counterbores on both sides of the piston maintain concentricity of the piston rods to each other as well as to the piston O-ring. The piston rods are connected by a high strength stud, sandwiching the piston between the rod faces. The assembly is torqued for proper preload of the stud and clamping of the piston head. Loctite® on the threads and faces assures sealing and locks the assembly against pounding and vibration. This procedure provides a positive and rigid assembly that will not allow...

Square 1 ® Cylinders Stroke collar of Delrin® Stroke Collar on piston rod Option How to Order 1) Start with the next longest stroke cylinder. 2) Select the amount the stroke is to be shortened. 3) Use the corresponding designation immediately after the stroke in the model number. Adjustable Retract Stroke For those “in-between” strokes, a STROKE COLLAR of Delrin® is incorporated on the piston rod. The collar fits tightly on the piston rod so that it cannot float as the piston is stroked. Tolerance on the stroke is ± 1/64". For tighter tolerances on the stroke or final rod position, contact engineering...

Option Specifications Nonrotating An internal piston guide pin prohibits rod rotation so that objects attached to or moved by the rod will not rotate. Incorporating the guide mechanism inside the cylinder saves you the time, space and cost of mounting external guide pins and bushings in and around your mechanism. The guide pin and bushing are also protected from damage by the environment, the atmosphere, or mechanical abuse. These internal parts are lubricated by the system lubrication.
