Parallel Grippers

Closing Grip and Opening Grip

Various Gripping stylesVarious gripping action : internal, external, by air or by spring force.

Uniquely Designed Roller Guide SystemThe longer distance between rollers longer enables smooth movement and gripping. E type (E shape retaining ring) is provided which withstands side moment load.

Multi-acting typeExtra thin body with 4㎜ (5/32") strokeA 10mm width body which incorporates 8mm bore cylinder enables high grippingforce. Ideal for narrow pitch/multi-station use.

Short body with 6㎜ (0.24") stroke (16.4mm width (0.65"))Wide stroke type enable making an equipment compact

Super light weight with 8㎜ (5/16") stroke (23.6mm width(0.93"))About 1/2 of the weight of the conventional grippers of the same class and model

Either the center port or the side port can be used as the air supply port.Sensor switches are provide (sold separately)Choosing from 6 types depending on the application

Single acting typeMiniature body but wide strokeThe smallest body as a 6㎜ stroke in the industry.（internal investigation）

10㎜ (0.39")width model is the lightest in the industry.A small gripper with secure gripping.

Single acting gripper yet can be used either Normally Open or Normally Closed.

Eco design - single acting saves air consumption.
