40mm x 825mm Hollow Linear Shaft
The 40mm x 825mm Hollow Linear Shaft is an excellent choice for applications requiring reduced weight without compromising structural integrity. Featuring a precision-engineered hollow core design, this shaft delivers exceptional rigidity and load-bearing capabilities while maintaining a significantly lighter profile than solid alternatives.
Key Specifications:
- Shaft Diameter: 40mm
- Inside Diameter: 26mm
- Length: 825mm
- Material: Carbon Steel (C60)
- Tolerance: h7 (precision grade)
- Brand: INA
- Reference: WH40/H7X26-C60-825
Ideal Applications:
This hollow linear shaft is perfectly suited for use with linear bearings in a wide range of automated systems, including:
- CNC machinery and precision equipment
- Robotics and automation systems
- Material handling and conveyor systems
- Industrial automation applications
- Extended-length linear motion control systems
- Heavy-duty assemblies requiring weight reduction and extended travel
- High-precision mechanical assemblies requiring dimensional accuracy
The precision h7 tolerance ensures excellent compatibility with standard linear bearings, providing reliable linear motion performance. This larger diameter shaft combines the rigidity needed for demanding, extended-length applications with the weight savings required for energy-efficient systems.
