|Rotary Actuators

Is it possible to retrofit an angle adjuster unit to a CRB2 or CRBU2 series rotary actuator? If so, how?

What is the backlash of the rotary actuator (rack pinion type)?

During assembly, why can’t I rotate the angle adjuster unit of my CDRB2BWU rotary actuator by hand or by applying pressure?

In order to set the angle adjuster unit of a CRB2BWU rotary actuator (size 10 to 40) to 180°, do I need to select the 270° option?

If the internal leakage of a CRB series vane type rotary actuator has increased, should the seals be replaced?

What are the effective torque and air consumption of CR□/MS□ series rotary actuators?

What is the size selection method for rotary actuators?

Can intermediate stops of a rotary actuator be performed by a closed center valve?

Can an MSQ□(10 to 200)A with an adjustment bolt be changed to an MSQ□(10 to 200)R with an internal shock absorber?

The angle of my MSQ□30A is adjusted to 90°, but when an external force is applied in the opposite direction of rotation at the rotation end, what appears to be backlash occurs. What is happening?

Is there a rotary actuator that rotates (distributes) 90 degrees to the left and the right?

The rotating angle of my CRB2BS20-180SZ exceeds 180° when rotating. Is there a way to adjust it so it doesn’t exceed 180°?

Is there a way to set the angle of a CDRQ2BS40 to 50°?

Can the angle of a CDRQ2BS40-180 be set to 120°? Also, what is the difference between the change of rotating range and the change of angle adjustable range special order options?

For CDRB2BW□-□-T79 auto switches, what is meant by “right-handed” and “left-handed”?

When ordering a foot type CRA1LS50, is the foot bracket mounted at the time of shipment? Also, in the catalog, the shaft is shown as being perpendicular to the foot bracket mounting surface, but can it be rotated 90° so that the shaft and foot bracket are parallel?

For the CRA1BS50-90CZ, at what point before the end of the rotating angle does the air cushion act?

What is the difference between CRB series rotary actuators with single and double vanes?

MSQ series rotary tables are available in sizes 1, 2, 3, and 7 as well as sizes 10, 20, and 30 to 200. What is the difference? Also, there is an MSQ series rotary table with an external shock absorber. Does it have any advantages over the type with an internal shock absorber?

When pressure is applied from port B of a CRB1BW50-180S rotary actuator, air leaks slightly from port A. What are the potential causes of this?

What is the difference between CRB and CRB2 series vane type rotary actuators (which both come in sizes 10, 15, 20, 30, and 40)?

There is a clean room specification for CRB1 series rotary actuators. Does this mean there is a clean room specification for CRB2 series rotary actuators as well?

What is the type of grease used inside CRA series rotary actuators, and can the standard grease and fluorine grease (special order part number suffix “-XC30”) be ordered separately?
