Due to the shape when a prestressed power spring is released, it assumes an S shape, while power spring assumes a spiral shape. However, prestressed power springs can store 25% ~ 55% greater energy than power springs. It also has higher turns than power spring when their size are the same.
1. Pre-stressed power springs are pre-stressed to produce a flatter torque gradient than conventional power springs.
2. Pre-stressed power spring can store 25% ~ 55% greater energy than power springs.
3. Pre-stressed power spring also has higher turns than power spring when their sizes are the same.
