　 Shock Guard 　TGF Series

Features superb recovery position precision. Perfect for attaching tables or indexers.

Type 2: Can be attached directly to timing pulleys. Shaft fastening screws can be tightened from the outside.
Type 3: Thinner than the type 2 version, perfect for attaching to power locks.
Type 5: Coupling type combined with an Echt-Flex to allow angular errors.
Type 7: Coupling type combined with an Echt-Flex to allow angular and parallelism errors.
Precise attachment face: A pre-load is applied to the support bearings to eliminate gaps, and along with the attachment faces being ground results in increased precision.
High precision: Features minimal backlash and high precision return positioning. Perfect for indexers.
Single position type: The ball and pocket arrangement, which are the torque transmission elements, can only be engaged in one place for a unique combination.
Simple torque adjustment: Features a torque scale -- just turn the adjustment nut (bolt) to freely adjust the trip torque.
It will automatically reengage after the cause of the overload has been removed by just turning the drive side.
