|---|---|---|---|
| Dovetail Slides | Feature a dovetail-shaped cross-section to prevent lateral movement. | Cost-effective, stable under heavy loads. | Higher friction, requires lubrication. |
| Linear Bearing Slides | Use ball or roller bearings for low-friction linear motion. | Smooth motion, high precision, low maintenance. | May require more space for installation. |
| Hardened Way Slides | Designed for high durability and wear resistance. | Excellent for heavy loads, minimal maintenance. | Higher initial cost, may be overkill for light tasks. |
Detailed Overview of CNC Linear Slides
Dovetail Slides
Dovetail slides are one of the most cost-effective slide solutions. They feature a dovetail-shaped cross-section that prevents lateral movement and provides stability. With strong construction and a range of load-bearing capabilities, they’re great for machine applications. Dovetail slides are commonly used in lathes, milling machines, and metalworking equipment.
Linear Bearing Slides
Linear bearing slides, also known as linear rails, deliver low-friction linear motion in a compact package. They use ball or roller bearings inside a carriage, which rolls along a rail with the load on top. This design allows for precise control over position and movement, making them ideal for applications requiring smooth motion and high precision, such as CNC machining and robotics.
Hardened Way Slides
Hardened way slides are designed to resist wear and handle heavy loads while delivering stable linear motion. They are made from high-hardness materials and undergo a heat treatment process to enhance their durability. These slides are ideal for high-production applications, such as feeding devices and shuttle systems, where minimal maintenance and high reliability are essential.
