HIR Domestic Ball Screw: Full Interchangeable Replacement Solution for THK Ball Screw

1: Background: Global Imported Ball Screw Supply Pain Points

Ball screw is the core linear transmission component of CNC machine tools, industrial robots, semiconductor equipment, lithium battery automation and packaging machinery. For decades, THK ball screw occupies a large share of the global high-precision market with mature precision technology and stable product performance.

However, overseas equipment manufacturers have long encountered prominent procurement pain points when purchasing THK ball screws:

1. Long unstable delivery cycle: Affected by international logistics, customs clearance and factory production scheduling, the delivery period of standard THK models often exceeds 8–12 weeks, which seriously delays equipment R&D and mass production progress.

2. High overall procurement cost: Import tariffs, ocean freight and brand premium push up the total cost by 30%–50% compared with domestic equivalent products, compressing equipment manufacturers’ profit margins.

3. Limited non-standard customization: THK has strict MOQ restrictions on special lead, special flange and ultra-long/short screw shafts, unable to respond quickly to small-batch non-standard demands of non-standard automation factories.

4. Slow after-sales technical support: Cross-border communication and overseas after-sales channels lead to slow response speed for size matching, failure troubleshooting and on-site guidance.

Against the backdrop of global industrial supply chain localization and import substitution trend, HIR Precision launches a full series of interchangeable ball screws specially developed to replace THK ball screws, solving the above industry pain points in one stop.

2: Core Advantages of HIR Ball Screw Replacing THK Ball Screw,100% Interchangeable Mounting Size, Direct Replacement Without Modification

HIR’s R&D team fully maps the dimensional standards of THK BNK, DIK, BLK, SBN series ball screws. All core dimensions including screw shaft outer diameter, lead, nut flange size, mounting hole position, thread length and preload structure are consistent with THK original specifications.

Customers can directly remove the original THK ball screw and install HIR products without modifying the machine tool base, slide table or transmission structure, greatly reducing replacement labor costs and downtime loss.

3. Equivalent Precision Grade, Stable Performance Matching THK Standard

HIR adopts high-purity alloy bearing steel, vacuum quenching heat treatment and six-axis linkage precision grinding technology. The screw surface hardness reaches HRC58–64, with uniform internal stress and low thermal deformation during high-speed operation.

• Precision grades covered: C3 ultra-precision, C5 industrial precision, C7 general transmission, fully aligned with THK precision classification;

• Technical index: 300mm travel cumulative lead error ≤5μm for C5 grade, repeated positioning accuracy up to ±0.001mm, smooth operation, low vibration and low noise, suitable for high-precision processing and positioning scenarios;

• Long service life: Optimized circulation ball channel design improves wear resistance, service life reaches the same level as THK original screw under the same load working condition.

 4. Short Delivery Cycle, Flexible Customization Support

• Standard models in stock: Mass inventory of common specifications such as 1605, 2010, 2510, 3210, delivery within 3–7 working days;

• Non-standard customization: Support custom screw shaft length, special processing at both ends, customized preload, dust-proof sealing structure, small batch order without high MOQ, delivery cycle shortened by 4–6 weeks compared with THK.

 5. Local Fast Technical & After-Sales Service

HIR equips professional linear motion engineers to provide free parameter matching, load calculation and model selection scheme. Online technical support responds within 15 minutes, and overseas customers can obtain remote installation guidance, failure analysis and spare parts replacement service efficiently without cross-border waiting.

 Main Application Scenarios of HIR THK Alternative Ball Screw

HIR interchangeable ball screw can fully replace THK original products in all mainstream precision equipment industries:

1. CNC machining centers, lathes, milling machines, grinding machines;

2. Industrial robots, linear modules, handling automation equipment;

3. Lithium battery production lines, photovoltaic assembly equipment;

4. Semiconductor testing equipment, medical precision instruments;

5. Food packaging machinery, 3C electronic automation equipment;

6. Laser cutting, engraving and plasma processing equipment.

Customer Practical Test Feedback

Many European, Southeast Asian and North American automation equipment manufacturers have completed batch replacement verification: After replacing THK ball screw with HIR equivalent model, the equipment positioning accuracy, running stability and continuous operation cycle have no obvious difference from the original imported parts, while the comprehensive procurement cost is greatly reduced and the supply chain stability is significantly improved.

A Malaysia non-standard automation manufacturer commented: “We used to purchase THK ball screws for our robotic arm production, often facing 3-month delivery delay. After switching to HIR interchangeable ball screws, delivery only takes 5 days, the machine operation accuracy remains stable, and our overall production cost drops by nearly 40%.”
