- *1For the gripping force at each gripping point, refer to the data in "Effective Gripping Force" in the manufacturer's catalog.
The effective gripping force is the value at the middle position of the opening/closing stroke. - *2Values in parentheses () show the MDHR weight. However, it does not include auto switch weight.
- *3Use this product with no lubrication. Using lubrication could cause sticking or slipping.
- *When the finger opening/closing speed is set as the total stroke of 0.2 seconds or more, it may cause the product to stick or completely stop its movement.
