Parallel Gripper( C ) KH ( L ) Series◆Compact and lightweight

Compact and lightweight thanks to the link mechanism.

◆Easy centeringThanks to the parallel shift, centering is easy and better
general versatility compared to the rotary type.
Long life because a ring bearing is used for the sliding part.

◆Same main body dimensions〈（C）KHL series〉
The main body dimensions are same as those of theKHL without a switch, so they are compatible.

◆Switch position adjustment available

The switch position adjustment is available. Therefore,
you can check the lever opening/closing and adjust
the workpiece diameter check by ﬁne adjustment.

◆It has the successive feature of the KH
series. Also, its opening/closing strokeis the long type.〈（C）KHL series〉◆2 faces have a port. Select the one you use
according to the mounting condition.〈（C）KHL series〉

Note) The grip force of φ16 is an eﬀective value when the grip point L is 20 mm and the pressure is 0.5 MPa.
The grip force of φ20 and φ32 is an eﬀective value when the grip point L is 30 mm and the pressure is 0.5 MPa.
