HIR is a professional manufacturer focusing on the R&D and production of domestic linear motion products. Rooted in mature precision manufacturing technology, the brand has completed localized production, technical upgrading and after-sales service layout in China.
With standardized production workshops and strict quality control systems, HIR has achieved large-scale mass production of ball splines. It has broken the long-term market monopoly of foreign brands, and gradually become a mainstream choice for domestic enterprises to realize import substitution. The brand is committed to supplying high-quality, cost-effective linear motion components and supporting the upgrading of domestic intelligent manufacturing equipment.
A complete HIR ball spline consists of spline shaft, spline nut, steel balls, retainer and sealing parts. Adopting rolling friction structure, it effectively reduces running resistance and realizes smooth compound movement of linear travel and rotation.
According to load capacity, torque rating and usage requirements, HIR ball splines are divided into multiple series:
Light & Medium Torque Series: Compact structure, flexible movement, suitable for general automation equipment, assembly machinery and low-load operating conditions.
High Rigidity & High Torque Series: Designed with multiple rows of steel balls and optimized raceway structure, featuring high load capacity, small rotational clearance and excellent rigidity, applicable to high-precision and heavy-duty working scenarios.
All products are available in two processing types: rolled type for cost-effective conventional use, and precision ground type for high-precision demanding occasions.
Precision ground spline shafts are processed with sophisticated grinding technology, with excellent surface finish and tight geometric tolerance. The products deliver high repeat positioning accuracy, small running clearance and stable operation, which fully meet the precision requirements of high-end automation equipment.
Optimized contact angle and uniform load distribution design greatly improve radial load capacity and torsional resistance. The products can withstand complex loads such as vibration and impact during operation, ensuring structural stability under long-term continuous working conditions.
Rolling friction replaces traditional sliding friction, bringing low friction coefficient, high transmission efficiency and low wear. Equipped with high-performance sealing components, the ball splines are dust-proof and anti-pollution, adapting to various harsh working environments and extending the overall service life.
Benefiting from domestic production and localized supply chain, HIR ball splines have obvious advantages in product price and delivery cycle compared with imported brands. Fast delivery and responsive after-sales service effectively reduce the procurement cost and downtime risk for manufacturers.
HIR domestic ball splines are widely used in various industrial sectors:
Industrial Robots: Applied to robot joints, lifting axes and moving units to realize flexible linear and rotary compound motion.
Semiconductor & Electronic Equipment: Used for wafer handling, precision positioning and 3C product assembly equipment, meeting high-precision and clean working requirements.
CNC Machine Tools & Machining Equipment: Served for spindle transmission, turret and feeding systems to guarantee equipment rigidity and machining accuracy.
Automation Production Lines: Ideal for packaging machinery, conveying equipment and automated handling systems.
New Energy Equipment: Applied to photovoltaic, wind power and other new energy facilities, adapting to outdoor and long-term continuous operation conditions.
Against the background of domestic substitution of industrial core components, HIR ball splines stand out among domestic products with reliable quality, diversified product lines, remarkable cost performance and complete service system.
As a representative domestic brand of ball splines, HIR not only provides cost-effective import substitution solutions for downstream manufacturing enterprises, but also continuously promotes the independent development of China's precision linear motion industry. With continuous technological innovation and quality improvement, HIR will further expand its application scope and contribute more to the development of domestic intelligent manufacturing.
