As a leading ball self-reversing screw manufacturer,LMT is committed to delivering top-tier precision transmission solutions.Our self-reversing screw products are engineered to meet the highest standards of durability and performance,making them the ideal choice for industrial automation and smart upgrading.

Ball self reversing screw and block nut operate with the cooperation of steel balls.With the ball self-reversing screw product,only one direction of rotation is required to achieve reciprocated bi-directional lateral movement.


Our self-reversing ball crews feature a unique internal structure and are manufactured using high-performance wear-resistant materials combined with advanced German heat treatment technology.This process significantly enhances surface hardness and toughness,resulting in extremely low wear rates even under high-speed and heavy-load conditions.The self reversing screw ensures near-zero backlash and smooth operation,providing exceptional accuracy and stability for various applications.

MOQ: 1 pc.
Fast delivery:15days.
Cost-effective:20% ~40% cost savings.
Low friction coefficient and high efficiency:The ball self reversing screw significantly reduces friction,resulting in lower drive torque and improved energy efficiency.
High speed operation with minimal heat generation:Designed to support rapid feed rates while producing little heat,enhancing durability and operational stability.
Design & Optimization Services:We assist customers in designing self-reversing screws and optimizing their current designs to achieve better performance and reliability.
Raw Material Control
We purchase raw materials only from qualified high-quality suppliers.Each batch of materials has complete material certification,material test report and quality inspection certificate.


Professional Testing
We use professional testing equipment and tools to strictly inspect product size, appearance and performance.
100% Double Inspection
Every self-reversing screw goes through 100% inspection.First,the factory conducts initial inspection; then the export department does secondary inspection.Products are delivered only after both inspections are passed and results are confirmed correct.

Operation & Function Test Videos
We will send customers operation videos of self-reversing screws,pawl and nuts,together with function test videos and pictures.
Product & Packaging Details Confirmation
We will send customers detailed product pictures and all packaging pictures before shipment to ensure all details meet customer requirements.
