**Q: What are the common materials of self-reversing screw and nut block?** A: （1）Common materials for self-reversing screw: C45,SS303,SS304,440C,SS316,SS316L,40Cr,titanium alloy,2507 duplex stainless steel,GCr15,POM,nylon,38CrMoAl. （2）Common materials for matching nut block: Brass,bronze,aluminum,C45,SS303,SS304,440C,SS316,SS316L,POM,PEEK,nylon.   - **Q: What are the common applications of self-reversing screws?** A: Self-reversing screws are widely used in various industrial and mechanical scenarios,including:   1.Tethered drones 2. Ship deck equipment 3. Pipeline robots 4. Winding machines (including carbon fiber winding machines and strapping band winding machines) 5. Hose reelers / hose retractors 6. Agricultural sprayers (hose retraction systems for sprayers) 7. Textile machinery  8. Large-scale oilfield equipment   - **Q: Why are same materials not recommended for designing self-reversing screw and nut?** A: When self reversing screw and nut adopt the same metal material, they are prone to galling, adhesion and seizure under friction and pressure operation. Identical material crystal structures easily bond with each other, resulting in thread locking, abnormal wear and short service life. Different material matching can effectively avoid bite failure, reduce friction and ensure stable long-running of reciprocating motion. - **Q: How does the efficiency of plastic nuts compare to copper alloy nuts?** A: Plastic nuts generally have a 10% higher transmission efficiency than copper alloy nuts. - **Q: What is the typical transmission efficiency of a trapezoidal lead screw?** A: The transmission efficiency of a trapezoidal lead screw is generally between 20% and 40%.
