Product Features
1. High precision control
Through precision machining processes such as grinding and quenching, and the design of ball/roller circulation structures, micrometer level repetitive positioning accuracy can be achieved. Optimization of ball components, eliminates motion lag and improves smooth operation.
2. Low friction and high efficiency
Using rolling friction ,energy consumption is reduced by more than 60% compared to sliding friction, and high-speed motion is supported .
3. High rigidity load capacity
The four column ball/roller layout and preloading adjustment technology can withstand composite loads (radial, axial, moment), and static loads can reach hundreds of kilonewtons. There is also heavy-duty optimization, which increases the contact area of roller guides by three times and is suitable for high impact scenarios such as stamping equipment.
4. Long lifespan and reliability
Hardened steel guide rail with multi-layer sealing protection, excellent wear resistance, and a service life of tens of thousands of hours.
Anti environmental erosion, dust-proof and waterproof structure, and high/low temperature resistant materials, suitable for harsh environments such as semiconductor workshops and food machinery.
5. Modularity and adaptability
Standardized size and installation hole design, compatible with mainstream brand interfaces, supporting quick replacement and system expansion.
Compact design: micro rail slider suitable for space limited scenarios such as 3C electronics and medical equipment.
