Precision Hollow Linear Shafts by MULTISTEEL for Industry Use

Hollow linear shafts are manufactured from high-quality steel, carefully processed for precision and durability. Each shaft are chrome plated and undergoes precision grinding and polishing to achieve tight dimensional tolerances and a smooth surface finish. The hollow structure allows a significant reduction in weight without compromising strength or stiffness, making it suitable for high-speed or lightweight machinery applications.

Customization options are available for diameter, length, and surface treatment, allowing clients to integrate shafts seamlessly into their machinery. The high hardness surface ensures long-term wear resistance, while the precise machining guarantees smooth and accurate linear motion. These hollow shafts are designed for demanding industrial environments where reliability and performance cannot be compromised.

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.

When to Choose Hollow Shafts

Systems where reducing weight and inertia improves performance.
Industrial equipment requiring precise, smooth motion with lower energy consumption.
OEM and custom solutions where flexibility in design is required.

When to Choose Solid Shafts

High-load applications requiring maximum rigidity.
Environments with minimal space or where shaft deflection must be strictly controlled.
Heavy machinery where weight is less critical than durability.

FAQs

1. What is a hollow linear shaft?
A hollow linear shaft is a cylindrical rod with a hollow center, designed for linear motion applications. It is lighter than a solid shaft, which reduces system weight and inertia. Hollow linear shafts are commonly used in CNC machines, automation systems, and precision equipment.

Their lightweight design improves energy efficiency and allows faster, smoother movement. High-precision machining ensures accuracy, and surface hardening improves wear resistance, making hollow linear shafts reliable for long-term industrial use.

2. What are the disadvantages of a hollow shaft over a solid shaft?
Hollow shafts have some limitations compared to solid shafts. They are slightly less rigid, so they may bend or deflect under very high loads. Hollow shafts can be more sensitive to torsion and extreme stress.

Custom machining and surface treatment may also increase their cost. While they save material and reduce weight, hollow shafts may not be ideal for applications requiring maximum strength and stability.

3. What are hollow shafts used for?
Hollow shafts are used in applications that require precision linear or rotational motion while keeping weight low. Common uses include CNC machines, robotics, automation systems, medical equipment, and aerospace devices.

They are also suitable for shafts that need to carry bearings or other components inside the hollow space. The combination of precision, durability, and reduced weight makes them popular in industrial and high-tech machinery.

4. How are hollow shafts made?
Hollow shafts are made from high-quality steel or alloy materials. The manufacturing process typically involves precision machining, drilling, and turning to create the hollow center. After shaping, shafts undergo surface hardening or coating to improve wear resistance and durability.

Some shafts are polished to achieve tight tolerances, straightness, and smooth motion. Custom hollow shafts can also be produced to meet specific diameter, length, and performance requirements for industrial applications.
