Lever Retracted Lower than the Clamping Point
Large lever retraction allows for wide angle of loading and unloading workpieces between operations.
Enables to Clamp Difficult Clamping Points
The compact lever-operating range enables to clamp difficult clamping points.
Excellent Coolant Resistance
Our exclusive dust seal is designed to protect against high pressure coolant. It also has high durability
against chlorine-based coolant by using a sealing material with excellent chemical resistance.
Standard Lever is also Available as an option

For further information, refer to the product catalogs of Auto Switch (JEP) and High-Accuracy Sensor for Air Cylinder (JES) on our website. When using an auto switch not made by Kosmek, check specifications of each manufacturer. 2. Auto Switch / High-Accuracy Sensor for Air Cylinder may be stuck out of the link clamp depending on the installation position and direction. ※1. The detection range of High-Accuracy Sensor for Air Cylinder (JES) is different from that of Auto Switch (JEP), and even small stroke can be securely detected by JES. Refer to “Performance Curve” on the JES catalog for further information. ※2. When detecting both lock and release positions with High-Accuracy Sensor for Air Cylinder (JES), please use two S-pole sensors. ※3. JEP/JES series cannot be used in an environment which generates a magnetic field disturbance. Please use D-P3DWA (manufactured by SMC) for those environments. -

Work P： Supply Air Pressure (MPa) piece Notes : ※1. F：Clamping Force (N), P：Supply Air Pressure (MPa), L：Lever Length (mm). Cylinder force (When L=0) cannot be calculated from the calculation formula of clamping force. 1. The table and graph show the relationship between the clamping force (kN) and supply air pressure (MPa). 2. Values in the chart indicate clamping force when the lever locks a workpiece in horizontal position. 3. The clamping force varies depending on the lever length.
