Hollow Linear Shafts | Custom Design for Industrial Automation

Hollow Linear Shaft Customized for Industrial Automation

BOS Hydraulic's hollow linear shafts represent a specialized class of high-precision components, engineered to provide exceptional structural support within linear motion systems across various industrial equipment. Their innovative hollow architecture significantly reduces overall mass without compromising rigidity, rendering them an ideal solution for applications where maximizing performance and operational efficiency is critical.

Optimized Hollow Design: The strategic removal of core material achieves a substantial reduction in weight, thereby enhancing the dynamic response and reducing the inertia of the moving system.
Broad Compatibility: Designed for seamless integration with standard linear bearings and bushings, facilitating straightforward assembly and reliable performance.
High-Hardness Surface: The shaft surface possesses exceptional hardness, providing superior resistance to wear and extending service life even under continuous operation.
Superior Surface Finish: A meticulously finished surface topography minimizes rolling or sliding friction, contributing to exceptionally stable and smooth motion.

Specificatinos of Hollow Linear Shafts

Hollow Linear Shaft vs Solid Shaft

Feature	Hollow Shaft	Solid Shaft
Weight and Inertia	Lighter weight reduces system inertia, enhancing dynamic performance and energy efficiency.	Heavier, offering more rigidity but higher energy consumption.
Rigidity and Strength	Maintains structural integrity but slightly less rigid; ideal where reduced weight is critical.	Offers maximum rigidity, suitable for high-load conditions.
Cost Considerations	Material savings can reduce cost in large systems; custom machining may increase unit price.	Simpler manufacturing often reduces initial cost but increases total system weight.
Precision and Stability	High-precision machining ensures smooth, repeatable motion; slightly more sensitive to deflection under extreme loads.	Excellent stability under heavy loads, maintaining straightness and roundness over time.
Maintenance and Durability	Surface-hardened treatment extends service life; lightweight design reduces wear on supporting components.	Extremely durable, resistant to bending and deformation under stress, but heavier systems may increase wear on bearings.

Opt for a Hollow Linear Shaft when:

System performance can be enhanced through the reduction of moving mass and inertial forces.
Industrial equipment requires exceptionally precise and smooth motion while aiming for lower energy consumption.
The application involves OEM or custom-engineered solutions where design flexibility and weight optimization are paramount.

Choose a Solid Shaft when:

The primary requirement is for high-load capacity and absolute maximum rigidity.
Operating environments present severe spatial constraints or where any shaft deflection must be stringently controlled.
Applications involve heavy machinery where ultimate durability takes precedence over weight savings.
