The ball screw is a Roller screw drive with balls as rolling elements, it serves to implement a rotational movement in a longitudinal movement or vice versa. Versatile are the requirements and the designs of a ball screw in practice.
Advantages of a ball screw:
- The efficiency is up to 98% for ball screw
- Higher service life due to almost wear-free running, due to the rolling friction only small losses occur.
- Low drive power required
- When rolling friction and high efficiency, the heating is correspondingly low
- Accurate positioning
- Higher process speeds
- No stick-slip effect
By a rotational movement of the spindle creates a longitudinal movement of the mother.
By a longitudinal movement of the nut creates a rotational movement of the spindle.
By a longitudinal movement of the spindle creates a rotational movement of the nut.
By a rotational movement of the nut creates a longitudinal movement of the spindle.
The efficiency is up to 98% for ball screw, compared to the trapezoidal screw drive, which reaches a maximum of 30% due to higher friction losses.
This results in a very effective conversion of rotary into longitudinal movement.
We offer you ball screws in swirled, ground and rolled quality, which have proven themselves by low pitch tolerances and excellent surface quality.
Advantages of our production possibilities:
- Cost-effective production for small and medium quantities
- Series production of large quantities
- Production of special gradients
- High dimensional accuracy
The nut designs are all defined according to DIN 69051, in addition, customer-specific special shapes are manufactured.
Each ball screw drive receives a quality assurance check log after extensive inspection..
