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 requi red for instal lat ion has been dramatically reduced. Improved installation accuracy and strength A centering boss has been provided to improve the installation accuracy. Also, because it is the directly mounted style, the strength has been increased. Two styles of installation Two styles of installations are available and can be selected according to the purpose: the front mounting style or the bottom mounting style. The CM2RK direct mount cylinder can be installed directly through the use of a square rod cover.

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 (mm) Standard stroke (mm) Note 1) Max. manufacturable stroke (mm) 20 25, 50, 75, 100, 125, 150 1000 25 25, 50, 75, 100, 125, 150, 200 32 25, 50, 75, 100, 125, 150, 200 40 25, 50, 75, 100, 125, 150, 200, 250, 300 Option: Ordering Example of Cylinder Assembly Tightening Torque: Tighten the cylinder mounting bolts for the bottom mounting style (Series CM2RKA) with the following tightening torque.
