Made to Order (For details, refer to pages 77 to 93.) Because it is a directly mounted style without using brackets, its overall length is shorter, and its installation pitch can be made smaller. Thus, the space that is required for installation has been dramatically reduced. Space-saving has been realized. Series CG1KR direct mount, non-rotating rod type cylinder can be installed directly through the use of a square rod cover. *1 The shape is the same as the existing product. Use the existing seal kit.

Please consult with SMC for strokes which exceed the standard stroke length. Note 1) Intermediate strokes not listed above are produced upon receipt of order. Manufacture of intermediate strokes at 1 mm intervals is possible. (Spacers are not used.) Note 2) Applicable strokes should be confirmed according to the usage. For details, refer to “Air Cylinders Model Selection” on front matter pages of the Best Pneumatics No. 2 or the WEB catalog. In addition, the products that exceed the standard stroke might not be able to fulfill the specifications due to the deflection etc. Bore size Standard stroke* 20 25, 50, 75, 100, 125, 150 25, 32 25, 50, 75, 100, 125, 150, 200 40, 50, 63 25, 50, 75, 100, 125, 150, 200, 250, 300 (mm) Weights Bore size (mm) 20 25 32 40 50 63 Basic weight 0.14 0.24 0.35 0.56 1.04 1.48 Single knuckle joint 0.05 0.09 0.09 0.10 0.22 0.22 Double knuckle joint (with pin) 0.05 0.09 0.09 0.13 0.26 0.26 Additional weight per 50 mm of stroke 0.05 0.07 0.09 0.15 0.22 0.26 Weight reduction for female rod end .0.01 .0.02 .0.02 .0.05 .0.10 .0.10 (kg) * A double knuckle joint pin and retaining rings are shipped together.
