Manufacturer profiles associated with Leaf Drive Mechanism.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The stroke length is typically in the range of 10–30 mm, depending on the specific model and clinical requirements. Always verify the exact value with the manufacturer.
It uses a high-precision motor, a low-backlash drive train, and closed-loop feedback from encoders or linear sensors. The positioning accuracy is typically ±0.05 mm, but this must be confirmed for the specific model.
The operating voltage is 24 V DC (±10%). Power consumption per leaf during motion is typically 10–30 W. These are reference values; check the manufacturer's specifications.
Maintenance typically includes periodic inspection of the drive train, lubrication if specified, and verification of position feedback. The mechanism is designed for a service life of at least 1,000,000 cycles. Follow the manufacturer's maintenance guidelines.
