MDHR3, Air Gripper, 3 Finger, Rotary Actuator with Auto Switch
The MDHR3 Series, 3-finger grippers are optimal for gripping spherical, cylindrical or round work pieces. Its cross roller guide provides smooth actuation for high precision and repeatability making it suitable for end-of-arm (end effector) or pick and place applications.
- Double acting, rotary actuated
- Bore sizes: 10, 15 mm
- High repeatability: ±0.01 mm
- Mounting: axial, lateral and vertical sides
- Auto switch capable

Lubrication
Note 1) Refer to page 532 “Effective Gripping Force” for details of gripping force at each gripping point.
Valve of effective gripping force is measured at the middle of opening/closing stroke.
Note 2) ( ) Value shows MDHR weight, but it does not include auto switch weight.
Note 3) This product should be used without lubrication. If it is lubricated, it could lead to sticking or
slipping.
When the finger opening/closing speed is set as the total stroke of 0.2 seconds or more, it may cause
the product to stick or completely stop its movement.
