Crémaillère et pignon
Les crémaillères de précision sont des composants de transmission essentiels conçus pour supporter et guider les mouvements linéaires dans les machines à commande numérique et les systèmes d'automatisation. Par rapport aux mécanismes traditionnels de transmission par courroie ou vis sans fin, les crémaillères de précision offrent une plus grande rigidité, une capacité de charge supérieure et des performances de mouvement sur longue distance plus stables, ce qui en fait une solution fiable pour les applications d'entraînement linéaire à grande vitesse et de haute précision.
Product Introduction
Our precision rack is a core transmission component designed for accurate linear motion and reliable power transfer in industrial automation systems. Manufactured from high-quality alloy and carbon steels such as C45, S45C and SCM440, the rack undergoes precision CNC machining and controlled heat treatment processes, including high-frequency hardening or quenching, to ensure stable tooth geometry and consistent performance.With carefully controlled tooth profiles, fine surface finishing, and tight pitch error tolerance, this rack delivers smooth meshing, low backlash, and stable motion even under continuous or high-load operation. The hardened tooth surface provides excellent wear resistance and long service life, making it suitable for demanding applications that require durability and positioning accuracy. Available in straight tooth, helical tooth, and oblique tooth series with multiple modules and sizes, our racks can be flexibly selected to match different pinions and motion requirements. We welcome customers to contact us for specification confirmation and application-specific selection support.

Product Features
High load capacity
Manufactured from high-strength alloy steel with controlled heat treatment, the rack is designed to withstand continuous high loads while maintaining stable transmission performance in demanding motion systems.
Excellent wear resistance
Through precision machining and surface hardening processes, the rack teeth exhibit strong wear resistance, effectively reducing tooth surface abrasion and extending service life under long-term operation.
High dimensional accuracy
The rack is produced using CNC grinding and strict tolerance control, ensuring consistent tooth profile accuracy and smooth meshing with pinions for reliable positioning performance.
Stable transmission performance
Optimized tooth geometry and uniform pitch accuracy help minimize vibration and backlash during motion, enabling smooth, stable, and repeatable linear movement in automation applications.
Strong structural rigidity
The solid rack structure provides high rigidity and resistance to deformation, maintaining alignment and transmission accuracy even under heavy loads and long stroke lengths.
Product Application
Precision motion transmission systems are widely used in modern CNC and automation equipment, where stable force transfer, accurate positioning, and long-term reliability are essential. In these systems, mechanical components must maintain high rigidity and dimensional accuracy under continuous load, ensuring consistent motion performance in high-speed and high-precision operations.
Rack components play a critical role in engraving machines and drive systems, converting rotational motion into precise linear movement. Manufactured from C45 steel with precision processing, the rack is well suited for engraving machine drive systems that require high bearing strength and positioning accuracy. With standardized specifications and stable performance, it is commonly applied in CNC engraving machines, woodworking equipment, and automated linear transmission setups, helping ensure smooth operation, reliable accuracy, and long service life in industrial applications.
