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.
