X-RAY Two jaws parallel stroke grippers, long stroke

FEATURES:

XRAY Grippers. Extreme Force and Torque.

The XRAY concept was developed for applications that impart high acceleration to heavy objects or require extremely long, precisely positioned jaws.

These applications put extreme stress on the gripper. XRAY grippers use a ceramic bearing system, the same system that is used in ZAYTRAN high load LSA actuators, to  isolate the precision jaw positioning system from jaw torque and force. The ceramic bearing rail allows the grippers to be small and light weight while delivering gripping force in excess of 2500N (560 pounds) and to tolerate jaw torque of 600NM (405 ft-lb).

XRAY grippers truly deliver: “Twice the force...Half the size”.

Patented Synchronous Technology - Extended Life

The synchronous XRAY utilizes ZAYTRAN US patent number 4591199.  The force and synchronizing double helix are independent systems.  The double helix works only to center the part to .025mm (±0.001 inches). All of the gripping force is provided by two pistons that are driven pneumatically. The independence of the force and synchronization systems  provides precision over the typical 10,000,000+ cycle life of the unit.

Rugged Construction-Low cost of Ownership

XRAY takes advantage of dynamic developments in both material science and automation technology to offer new horizons of toughness and cost efficiency. The cost of ownership of the XRAY is minimized by the use of off-the-shelf stainless steel cylinders.  These cylinders include magnetic sensing rings for enhanced flexibility in sensing. Unparalleled rigidity is achieved by combining a 32mm ground rod and ZAYTRAN’s proprietary ceramic bearing technology.  Anti-rotation of the jaw mounting system is achieved with polyamide imide bearings running in guides that are precision machined in the extruded backbone of the system.  All of these moving members are lubricated for the life of the XRAY. The application flexibility of the XRAY is extended by the use of an extruded aluminum backbone that provides multiple options for mounting the gripper and mounting sensors to the gripper as well as reducing the weight of the gripper.

Optional power-off brake

In applications that require the part be held even when pneumatic power is lost, the Power-Off Brake option  provides an excellent solution.  When pneumatic pressure is removed from the option a spring is allowed to rotate a collar that engages a collet brake system on the helix. Thus, the jaws are braked in position.

Either an encompassing jaw system or jaws with compliance must be used with this option. Jarring can cause some jaw movement.
