In the field of precision linear motion and torque transmission, THK ball splines have long occupied a dominant market position, relying on mature rolling friction technology, stable high-speed operation performance and excellent load-bearing capacity. They are widely used in core equipment such as industrial robots, automated handling machinery, precision testing instruments, semiconductor equipment and packaging machinery. However, affected by international logistics delays, brand premium pricing and regional supply shortages, more and more global machinery manufacturers are looking for reliable, cost-effective and fully compatible replacement solutions for THK ball splines.
Against this industry background, the domestic high-end brand HIR officially launches a full-series ball spline replacement product line, covering all mainstream models of THK ball splines including LT, LF, LBS and high-torque caged ball splines. Breaking the technical monopoly of imported brands, HIR ball splines adopt the same R-shaped curved groove design and precise ball circulation structure as THK products, converting sliding friction into efficient rolling friction, achieving ultra-low friction loss, high-efficiency torque transmission and zero-lag motion response, fully meeting the dual operational requirements of simultaneous linear movement and rotational torque transmission of precision equipment.
Full Interchangeable Installation, Zero Replacement Cost
HIR strictly follows THK’s original dimensional standards, tolerance parameters and installation specifications in product design and production. All shaft diameters, nut outer diameters, mounting hole positions, stroke ranges and preload grades are completely consistent with THK original parts. Customers can realize 100% direct replacement without modifying equipment molds, adjusting assembly procedures or redesigning structures, effectively saving equipment renovation time and additional replacement costs, and supporting rapid batch replacement and equipment maintenance upgrade.
Import-level Precision & Stable Core Performance
Adopting high-strength alloy steel integral forging and overall heat treatment process, HIR ball splines feature high rigidity, strong torsion resistance and excellent radial load capacity. The precision grinding process ensures the perfect fit between the ball and the raceway, with a motion accuracy error controlled within 0.1mm, a torque transmission efficiency of over 98%, and stable high-speed operation without jitter or noise. Equipped with an optimized ball retainer structure, it eliminates ball collision and friction, reduces particle generation, and achieves long-term maintenance-free operation, fully adapting to high-frequency, high-speed and high-load working scenarios of industrial automation equipment, reaching the same service life and stability level as imported THK ball splines.
Superior Supply Chain & Ultra-high Cost Performance
Different from THK’s long overseas production and delivery cycle and high brand premium, HIR, as a mature domestic precision transmission component manufacturer, has independent production bases, complete processing equipment and a perfect quality inspection system. It shortens the delivery cycle to 3-7 working days for conventional models, effectively solving the pain points of slow supply and out-of-stock shortages of imported parts. On the premise of consistent performance and precision, HIR ball splines eliminate intermediate import links, with a comprehensive procurement cost reduced by 20%-35% compared with THK original products, helping global customers optimize procurement budgets and improve product market competitiveness.
Wide Industrial Application Coverage
HIR alternative ball splines are widely applicable to industrial robot joints, automated linear sliding tables, logistics sorting equipment, precision testing machinery, semiconductor processing equipment, medical devices and other fields. Whether it is light-load precision micro-motion or heavy-load high-torque continuous operation, the products can maintain stable and efficient operating performance, providing reliable core component support for global manufacturing equipment upgrading and localized supply chain layout.
At present, HIR full-series ball spline replacement products have passed multiple precision tests and industrial field verification, and have won wide recognition from overseas customers in Europe, Southeast Asia, the Middle East and other regions. In the future, HIR will continue to focus on the R&D and iteration of precision linear motion components, provide global customers with higher-precision, more cost-effective and more stable imported alternative solutions, and help the manufacturing industry achieve efficient and low-cost intelligent upgrading.
