Introduction to Miniature, Lead, and Rolled Ball Screws and Support Units
I. General Definitions and Key Distinctions
As core linear transmission parts for automated machinery, these four products convert motor rotary motion into accurate linear reciprocating movement. Though applicable to precision machinery universally, they differ in precision, size, manufacturing techniques, and usage scenarios. They satisfy tiered industrial automation demands and support bulk procurement and system integration for overseas industrial equipment manufacturers and automation integrators.
Miniature Ball Screw: An ultra-compact precision part with a shaft diameter of ≤12mm and fine lead. It adopts a steel ball rolling transmission to cut friction drastically. Featuring miniaturization, high precision, and low noise, it serves micron-level fine adjustment in space-limited miniature precision equipment.
Lead Ball Screw: General-purpose precision transmission screws with complete lead options and stable running performance. It balances positioning accuracy and transmission efficiency, boasting the widest applicability for standard mid-to-high-end automation devices.
Rolled Ball Screw: Cost-effective mass-production screws made via cold rolling without fine grinding. With medium precision, it delivers a stable, large-scale supply and low processing cost, prioritized for cost-sensitive automated equipment.
Ball Screw Support Unit: Matching mounting accessories for all ball screws. It fixes screw shafts, suppresses vibration, and avoids shaft deflection, improving system running accuracy and component service life.

II. Specific Application Scenarios
All products target industrial B2B equipment integration, excluding consumer-grade devices, and align with procurement demands of overseas automation manufacturers, assemblers, and component traders.
Miniature Ball Screws: Semiconductor die-bonders, wafer fine-tuning structures, minimally invasive medical devices, optical inspection platforms, mobile phone lens assembly equipment, and compact precision 3D printers requiring micron-level positioning.
Standard Lead Ball Screws: 3C assembly lines, precision CNC machine tools, packaging machinery, new energy battery assembly, and automated handling robots requiring stable, high-precision transmission.
Cold-Rolled Ball Screws: Logistics sorting equipment, automated conveyor lines, small linear actuators, and general automation tooling with strict cost control and loose high-precision requirements.
Support Units: Universally compatible with domestic and imported ball screws, widely used in machine tools, automated production lines, and precision instruments to eliminate high-speed vibration and assembly deviation.
III. B2B Purchasing Motivations
The tiered product lineup solves four core pain points of overseas B2B buyers:
High import costs and long lead times: Performance matches European, Japanese, and American imported alternatives at 20%-40% lower procurement costs. Spot inventory supports immediate shipment to shorten delivery cycles.
Supply chain risks: Direct proprietary brand supply with no middleman markup ensures long-term stable bulk supply, avoiding overseas import shortage and delivery interruption risks.
Mismatched cost and performance: Tiered precision positioning prevents performance overkill or insufficient accuracy, helping buyers optimize equipment production cost matching.
Complicated multi-vendor procurement: One-stop supply of screws and matching support units cuts cross-supplier communication, logistics, and docking costs.
IV. OEM/ODM Service Overview
Customization only opens for corporate bulk orders; individual small orders are declined.
OEM Service: Private label production, including customized logos, packaging, and standard dimensional production per buyer drawings.
ODM Service: Customize lead, shaft length, nut structure, and dustproof/waterproof grades, plus modified mounting holes for non-standard equipment.
Supporting documents: Negotiable MOQs, official quality test reports, and conformity certificates provided for overseas customs clearance and equipment certification.
V. Solutions to Key Customer Pain Points
High-cost unstable imported screws: Independent domestic brand with equivalent import performance, spot bulk inventory, and faster after-sales response than overseas suppliers.
Vibration, low precision, and short lifespan: Tiered precision matching plus matched support units reduce running vibration and shaft deflection, extending component lifespan by over 30%.
Poor cross-brand compatibility and scattered procurement: Full-spec serial products with universal compatibility for new and legacy equipment, realizing one-stop procurement.
Low profit for mass-produced equipment: Low-cost cold-rolled screws reduce the buyer's terminal manufacturing cost and improve market competitiveness.
VI. Target Customer Base
We exclude individual consumers, DIY users, and household equipment purchasers. Qualified B2B clients include overseas automation manufacturers, machinery assembly factories, industrial component traders, import agents, non-standard automation integrators, and industrial equipment maintenance providers. Only industrial bulk orders are accepted.
VII. FAQ
Q1: Can they replace imported brands?
A: Yes. Miniature and standard lead screws match high-end imported counterparts, while cold-rolled screws fully replace low-end imported mass-production models with better cost performance.
Q2: Do you support bulk drop-shipping and OEM?
A: Yes. We provide full-container overseas delivery, OEM/ODM customization, and complete customs clearance and quality inspection documents.
Q3: Cross-brand compatibility of support units?
A: Standard units fit all mainstream domestic and imported ball screws; non-standard sizes can be customized for special installation demands.
