Trapezoidal lead screws are classic mechanical transmission components designed to convert rotary motion into smooth linear force transmission. Widely adopted across global industrial automation, conveyor systems and general machinery fields, they stand out as a budget-friendly alternative to precision ball screws for low-load, low-speed operational requirements. Manufactured by Shuntai, our custom trapezoidal screw assemblies deliver reliable performance tailored to diverse customer customization needs. Core Specifications of Our Custom Trapezoidal Screws Item Detailed Parameter Product Name Trapezoidal Lead Screw Brand Shuntai Raw Material GCr15 Bearing Steel, Carbon Steel, Bronze Nut Production Process Rolled Screw, Ground Screw Key Advantage Extended Service Lifespan Lead Time 7 Days for Standard Orders Preferred Shipment Port Shanghai, China Main Features of Trapezoidal Lead Screws Compared with high-precision ball screw products, trapezoidal lead screws have distinct performance characteristics that match targeted application scenarios perfectly: 1.Economical Production & Low Unit Cost   Their simplified machining workflow cuts down overall manufacturing expenses significantly. Without complex rolling component assembly, trapezoidal screws greatly lower procurement costs for equipment manufacturers with non-high-precision project budgets. 2.Stable Load Performance for Light-Duty Operations   Built for low-load and moderate-speed running conditions, these screws excel at basic force delivery instead of heavy-load high-cycle operations, matching most conventional automated equipment design standards. 3.Robust Self-Locking Performance with Moderate Friction   Higher internal friction than ball screws brings natural self-locking capability, which keeps equipment position fixed automatically once power is cut off. This unique trait eliminates extra locking parts for lifting and positioning machinery. 4.Tolerant Backlash for Non-Precision Positioning   While moderate backlash exists during reciprocating movement, this feature is acceptable for applications that don’t demand ultra-precise positioning, further cutting unnecessary production costs for low-accuracy machinery projects. Where Trapezoidal Lead Screws Are Commonly Used Thanks to their cost advantages and practical mechanical traits, Shuntai trapezoidal screws are extensively applied in: • General industrial automation equipment • Conveyor belt drive structures • Light-duty lifting machinery • Household and small-scale processing machinery • Custom manual adjustment devicesWhy Choose Shuntai Custom Trapezoidal Lead Screws? ✅ Flexible Customization: We support custom thread pitch, screw length and bronze nut structure according to clients’ engineering drawings.   ✅ Reliable Raw Material: Options include durable GCr15 bearing steel and wear-resistant bronze nuts to extend component service life.   ✅ Fast Lead Time: Standard customized items finish production within 7 working days to shorten your project waiting cycle.   ✅ Convenient Global Shipping: Goods depart from Shanghai Port, supporting flexible sea and air logistics for worldwide buyers.   If your upcoming machinery project requires cost-efficient linear motion parts without ultra-high speed or micron-level positioning needs, trapezoidal lead screws are your optimal pick.

In modern CNC machinery, automation production lines and linear guide modules, ball screws act as the core transmission component that converts rotary motion into precise linear movement. Without high-performance ball screws, your automated equipment cannot maintain stable positioning accuracy, smooth operation, or long service life. Today we will introduce our SHUNTAI high-precision left-hand thread ball screw series, covering two mainstream models: 1605 and 4010, with flange single ball nut design, customized non-standard sizes available for diverse industrial machinery demands. What Makes Our Ball Screws Stand Out? Premium Raw Material: GCr15 Bearing Steel All our ball screws are forged from GCr15 bearing steel, a high-strength alloy steel widely recognized in the transmission industry. This material delivers outstanding wear resistance, anti-fatigue performance and structural rigidity, drastically extending the service lifespan of the whole screw assembly even under continuous heavy-load operation. Dual Manufacturing Processes for Custom Needs We supply two production versions to match different budget & precision requirements: Rolled Ball Screws: Cost-effective, stable performance for general automation equipment, mass delivery supported. Ground Ball Screws: Ultra-tight tolerance, superior positioning repeatability, perfect for high-precision CNC devices.

When your automated machinery, CNC equipment, or automation production line needs stable, precise rotary-to-linear motion conversion, a high-performance ball screw becomes the core component you cannot compromise on. Shuntai DFU external circulation double nut ball screw is engineered to deliver ultra-smooth, low-noise, long-lasting linear transmission, widely adopted across industrial automation, machining centers, 3C automation, medical equipment, and precision testing machinery. What Is An External Circulation DFU Ball Screw? A ball screw is a mechanical transmission component that converts rotational motion into precise linear motion. It consists of threaded screw shaft and ball circulation nut assembly. Tiny steel balls roll between the screw thread and nut raceway, replacing sliding friction with rolling friction—this drastically cuts friction loss, boosting efficiency and accuracy compared to traditional trapezoidal lead screws. Our DFU external circulation double nut design optimizes the ball circulation path: the external deflector ensures smooth ball recycling without jamming, while the double nut structure enables adjustable preload to eliminate backlash entirely. The final effect: zero clearance movement, quiet operation, and consistent positioning accuracy over thousands of working hours. Core Product Specifications of Shuntai DFU Ball Screw Item Details Product Name DFU External Circulation Double Nut Ball Screw Brand Shuntai Main Raw Material GCr15 bearing steel; Optional stainless steel, alloy steel, carbon steel, aluminum, brass for custom projects Shaft Manufacturing Process Rolled screw shaft / Ground screw shaft Precision Grades Available C3, C5, C7 precision classes to match different accuracy demands Lead Time Standard stock models ship within 7 working days Loading Port Shanghai Port, China MOQ 1 unit sample available for performance testing Packaging Custom export-grade packaging per client requirements Standout Performance Features 1.Zero Backlash & High Rigidity The double nut preload structure fully eliminates axial clearance. The assembly maintains outstanding rigidity under heavy load, ideal for high-speed reciprocating positioning tasks that demand repeat accuracy. 2.Ultra Low Noise Smooth Operation Polished raceway surface and optimized external circulation loop reduce ball collision noise significantly. The whole unit runs quietly even at continuous high operating speeds, suitable for indoor precision equipment and noise-sensitive production workshops. 3.Extended Service Life & High Durability Core components use premium GCr15 bearing steel with strict heat treatment and surface hardening. Uniform load distribution on rolling balls minimizes wear, delivering stable performance for long-term continuous operation. 4.High Positioning Precision We supply three standard precision grades: C7 for general automation, C5 for mid-precision CNC machinery, C3 for ultra-precision lab equipment and high-end machining centers.
