What Are Linear Shafts?
A linear shaft is a mechanical component used to guide and support linear motion, typically paired with linear bearings or sliders to achieve low-friction, high-precision movement. They are commonly made from high-strength alloy steel, stainless steel, or surface-treated carbon steel to ensure durability and corrosion resistance.
Types of Linear Shafts
The types of linear shafts can be classified in detail based on their structure, material, and surface treatment. During the selection process
By Structure:
Solid Linear Shaft: High strength and rigidity, suitable for heavy loads and applications requiring stability.
Hollow Linear Shaft: Lightweight while maintaining rigidity, ideal for reducing overall system weight and accommodating wiring or tubing.
Chrome Plated Linear Shaft: Enhanced wear and corrosion resistance, perfect for humid or corrosive environments.
Spline Linear Shaft: Features splines along the shaft to transmit torque while enabling linear motion, commonly used in systems requiring combined rotation and linear movement.
Stepped Linear Shaft: Varying diameters along its length, designed to accommodate different components or mounting requirements.
By Material:
Carbon Steel Shaft: Offers high strength at a low cost, suitable for general industrial applications.
Stainless Steel Shaft: Provides excellent corrosion resistance, ideal for humid or specialized environments.
Alloy Steel Shaft: Delivers superior strength and wear resistance, commonly used in heavy-load applications.
By Surface Treatment:
Heat-Treated Shaft: Enhanced hardness and wear resistance.
Nickel-Plated Shaft: Additional protection against rust and corrosion.
