BKUA002 Ver.1.0 Air Cylinder TWIST CYLINDER INSTRUCTION MANUAL Ver.1.0 Handling Instructions and Precautions Mounting General precautions 1. When mounting an adjusting plate on the rod end, first secure the adjusting plate in place with a wrench or vise, as shown in the illustration below, and tighten a hexagon socket head bolt into the rod end female thread. Care must be exercised that removing or attaching the hexagon socket head bolt without securing the adjusting plate into place with a wrench, etc., could cause the piston rod to rotate, and could damage the rotating mechanism inside the cylinder. Use the same mounting procedure for mounting a fixture other than the adjusting plate to the rod end. Allen wrench Wrench Adjusting plate 2. When rod end brackets are separately manufactured and mounted, the mass and total length of the rod end brackets should not exceed the values shown below. Medium load type (RHDA) Bore size mm [in.] Rod end bracket mass g [oz.] Total length of rod end brackets mm [in.] 16 [0.630] 60 [2.12] 100 [3.94] 25 [0.984] 100 [3.53] 120 [4.72] 40 [1.575] 290 [10.23] 160 [6.30] Remark: Dimensions of the mounting portion are restricted. For details, see the AN dimensions and AP dimensions on p.1371. 3. When using the Twist cylinder as a clamp for workpieces, do not clamp the workpiece in the course of a swing motion. Clamping the workpiece in the course of a swing motion could damage the rotating mechanism inside the cylinder. 4. For installing the body mounting bracket to the cylinder, evenly tighten 2 hexagon socket head bolts at a torque of 392〜441N·cm [34.7〜39.0in·lbf] (reference values). When using a φ 40 [1.575in.] Twist cylinder with the body mounting bracket, set the pressure at 0.5MPa [73psi.] or less. Using at pressures exceeding 0.5MPa [73psi.] could result in cylinder thrust causing the cylinder body to move from the body mounting bracket. To use in the 0.5〜0.7MPa [73〜102psi.] range, use a mounting nut or rod cover mounting holes to directly install the cylinder body onto the device. Allen wrench Body mounting bracket 5. A piping adapter (order code: -L) can be used to change the piping direction to be perpendicular to the cylinder axis. To install the piping adapter, attach the provided O-ring to the piping adapter’s O-ring groove and then assemble it to the cylinder body. Piping Always thoroughly blow off (use compressed air) the tubing before connecting it to the Twist cylinder. Entering metal chips, sealing tape, rust, etc., generated during piping work could result in air leaks or other defective operation. Atmosphere 1. If using in locations subject to dripping water, dripping oil, etc., or to large amounts of dust, use a cover to protect the unit. 2. The product cannot be used when the media or ambient atmosphere contains any of the substances listed below. Organic solvents, phosphate ester type hydraulic oil, sulphur dioxide, chlorine gas, or acids, etc. Lubrication The product can be used without lubrication, if lubrication is required, use Turbine Oil Class 1 (ISO VG32) or equivalent. Avoid using spindle oil or machine oil. Media 1. Use air for the media. For the use of any other media, consult us. 2. Air used for the Twist cylinder should be clean air that contains no deteriorated compressor oil, etc. 3. Install an air filter (filtration of a minimum 40 µm) near the Twist cylinder or valve to remove collected liquid or dust. In addition, drain the air filter periodically. Collected liquid or dust entering the cylinder may cause improper operation. Twist Cylinder Selection Procedure To use Twist Cylinders, compute the following 3 values (conditions). 1. Allowable bending moment 2. Allowable kinetic energy Make concrete calculations to confirm whether the values (conditions) are satisfied. 3. Output torque 1. Allowable bending moment Select a type such that the bending moment on the rod end does not exceed the values listed below. R(m) Allowable bending moment (N·m)≧F (N)×R N·m [ft·lbf] Bore size mm [in.] R Medium load type (RHDA) 16 [0.630] 5.3 [3.9] 25 [0.984] 14.8 [10.9] 40 [1.575] 52.5 [38.7] F Note : When a Koganei adjusting plate is used for operation, the maximum operating pressure at φ16 [0.630in.] is 0.5MPa [73psi.]. 2. Allowable kinetic energy Kinetic energy is generated when a workpiece and a plate are mounted onto the rod end of the Twist cylinder and rotated. Use Twist cylinders at or below the allowable kinetic energy. First, calculate the kinetic energy. Kinetic energy E= 1 ω2 2J Kinetic energy E' = 1 ω2 2 J' E=Kinetic energy (J) J=Mass moment of inertia (kg·m2) ω=Average angular velocity (rad/s) E' =Kinetic energy [ft·lbf] J' =Mass moment of inertia [lbf·ft·sec.2] ω=Average angular velocity [rad/sec.] Calculation for mass moment of inertia J Calculation for mass moment of inertia J' The shape is assumed to be as follows. The shape is assumed to be as follows. J= R2 mR 3 R=Distance from rotation center to workpiece end (m) m=Mass (kg) J' = R w'R' 2 3g R' = Distance from rotation center to workpiece end [ft.] w' =Weight [lbf.] g=Acceleration of gravity=32.2 [ft./sec.2] R' Twist Cylinder Selection Procedure Calculation of average angular velocity ω θ ω=t 3. Output torque Do not apply torque to the Twist cylinder. The output torque is shown below for reference; it is not a guaranteed value. θ= Swing angle (rad) Twist cylinder is 1.57rad. θ=1.57(rad) t = Swing time (s) Shows the time required for the Twist cylinder’s total stroke operationNote to rotate by 90°, which is set as shown in the table below.

The kinetic energy E calculated above should be at or below the allowable kinetic energy listed below. Exceeding the allowable kinetic energy listed below could damage the rotating mechanism inside the cylinder, resulting in defective operation.

Calculation example Calculation example When a plate with the dimensions shown below is mounted on the rod end of the Twist cylinder, we select which bore size is the best. The total stroke is 30mm. The operation time is set at 0.8 second for one push or pull. When a plate with the dimensions shown below is mounted on the rod end of the Twist cylinder, we select which bore size is the best.

The sensor switch alone cannot be moved. ● To remove the sensor switch from the strap, first remove the strap from the cylinder tube and then remove the sensor switch from the strap. ● Tighten the mounting screw with a tightening torque of 49N·cm [4.3in·lbf].

Frequently asked questions
The manual states that air should be used as the media. Using other media may require consultation with Koganei.
The allowable kinetic energy depends on the bore size. For example, the allowable kinetic energy for a 16mm bore size is 0.003 J [0.0021 ft·lbf]. The manual provides a table with allowable kinetic energy for various bore sizes.
When the Koganei adjusting plate is used, the maximum operating pressure for a 16mm bore size is 0.5 MPa [73 psi].
