- Square Flange Structure Designed for High-End Automation: The spline flange is securely mounted to the equipment using bolts and allows for free adjustment of the axial position. It is particularly suitable for mechanical actuation applications involving extremely frequent forward and reverse rotations.
- Excellent Dust Sealing Protection: The outer cylinder comes standard with professional-grade dust seals and circulators, perfectly preventing the ingress of impurities and chips from the machining environment to ensure long-term operational stability.
- Gothic Arch Grooves and Zero Rotational Backlash: Utilizing a unique Gothic-arch 40° contact angle design, combined with precision ground grooves and accurate preload adjustments, it completely eliminates backlash in the rotational direction, enabling precise indexing even under frequent forward and reverse rotations.
- High Rigidity and Perfect Complex Load Capacity: Due to the large contact angle, it delivers an exceptional load capacity in both radial and torque directions. This effectively suppresses vibration and shock during high-speed equipment operation, providing excellent torque and moment rigidity.
- Lightweight, Compact, and Substantial Space Saving: Under the same shaft diameter conditions, the rated load capacity of the ball spline is more than ten times that of a traditional linear ball bushing. Its extremely compact structure can directly replace complex mechanisms, helping equipment achieve miniaturization and high-speed upgrades.
- Premium Alloy Steel and Ultimate Wear Resistance: The shaft and outer cylinder are crafted from select high-grade alloy steels (such as SCM440/SUJ2). Following professional heat treatment and quenching, the surface hardness reaches HRC 58~62, ensuring outstanding wear resistance and exceptional durability.
- High Cost-Effectiveness and Rapid Delivery: Through vertically integrated manufacturing management and large-scale production, costs are optimized to provide solutions that combine the quality of leading international brands with highly competitive pricing. A comprehensive stock of standard specifications is maintained to meet rapid delivery demands.
- Highly Flexible Custom Shaft End Machining: We support precision-customized end-machining services with maximum flexibility. Whether requiring stepped shafts, external threads, keyways, or special drilling, components can be precisely tailor-made according to customer blueprints to significantly shorten assembly time.
