CNC Linear Module Ball Screw

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. Left-Hand Thread + Flange Single Ball Nut Design Our featured left-hand thread configuration solves unique reverse transmission layout requirements that standard right-hand screws cannot satisfy. The integrated flange single ball nut enables easy mounting onto linear slide blocks, saving your mechanical assembly time without complicated auxiliary fixtures. Fast Lead Time & Reliable Logistics Production lead time: 7 working days for standard non-standard custom orders Shipment port: Shanghai, China, with flexible sea/air shipping solutions to global industrial markets Model Breakdown: 1605 VS 4010 Left-Hand Ball Screws 1. Model 4010 Ball Screw (40mm Diameter, 10mm Lead) The 4010 specification represents a screw shaft diameter of 40mm and a travel lead of 10mm per full rotation. Its core advantages include: • Higher rigidity & heavy load capacity thanks to the larger 40mm shaft body • 10mm medium lead: Fast linear travel speed while retaining stable transmission precision • Wide application scope: Large CNC machine tools, heavy-duty automation production lines, large-format linear modules, heavy-load industrial handling equipment 2. Model 1605 Ball Screw (16mm Diameter, 5mm Lead) The 1605 model features a 16mm shaft diameter with a 5mm lead per rotation, the top choice for compact precision machinery: • Compact 16mm diameter: Fits small and medium-sized automated equipment with limited installation space • 5mm small lead: Delivers ultra-fine positioning control, ideal for high-accuracy machining tasks • Superior manufacturing precision: Tighter geometric tolerances compared to large-diameter screw models, perfect for precision inspection instruments, small engraving machines, miniature linear sliding tables Quick Selection Guide • Pick 4010 ball screw: If you run large industrial machines, need heavy load bearing and fast linear moving speed. • Pick 1605 ball screw: If your equipment is compact-sized and demands ultra-high motion accuracy. Where Can You Use SHUNTAI Left-Hand Ball Screws? • Our flange single nut ball screws are universally compatible with all linear guide module systems, extensively applied in: • CNC milling, engraving and cutting machines • Automated assembly production lines • Precision testing and measuring equipment • Robotic linear motion axes • Medical automation machinery • Small & medium precision automation equipment Why Choose SHUNTAI Custom Non-Standard Ball Screws? 1.Custom non-standard sizing: We tailor shaft length, thread length, nut flange size to match your mechanical drawings. 2.Left-hand thread specialized production: We specialize in reverse thread ball screws, a hard-to-source component for many machinery builders. 3.Long service life: GCr15 steel + precise grinding/rolling craft reduces friction loss and lowers your equipment maintenance frequency. 4.Short turnaround: 7-day production cycle cuts your project waiting time compared to generic suppliers. 5.Export-ready supply: All products meet international industrial transmission standards, shipped from Shanghai port with complete export documentation.
