A trapezoidal screw is a power screw with a trapezoidal-shaped thread profile,characterized by a 30° flank angle.Unlike ball screws (which use rolling elements),they rely on sliding contact between the screw and nut.

Trapezoidal Leadscrew Information

When To Choose Trapezoidal Screws?

Low to Moderate Speed Applications: Trapezoidal screw rod generate more friction than ball screws,making them unsuitable for high-speed or high-efficiency systems.

High Load Capacity: Their robust thread design handles heavy static or dynamic loads effectively.

Self-Locking Requirement: The friction between the leadscrew and nut prevents back-driving,making them ideal for: Vertical applications where gravity could cause unintended movement (e.g., hoists).Safety-critical systems needing position retention without power. 

Budget Constraints: Trapezoidal screws are cheaper to manufacture and maintain than ball screws.Choose them if:Your project has tight cost limits.Long-term maintenance costs need to be minimized.

Harsh Environments: This trapezoidal thread screw perform better in dirty,dusty,or high-vibration settings where ball screws (with delicate rolling elements) might fail.

Low Accuracy requirement: Trapezoidal screws have more inherent backlash.The screw is Suitable for applications where ±0.1 mm precision is acceptable.Use anti-backlash nuts if higher precision is needed.
