Product Description

Guideway flat rail rack

Precision-engineered flat rail rack made from hardened alloy steel, featuring accurately ground teeth for smooth meshing with
pinion gears. Designed for high-load, high-precision linear motion in CNC machines and automation systems, offering durability and
long-term performance.

The flat rail rack integrates linear guidance and power transmission in a single component, serving as both a structural rail and a driving element in the guideway system. It works with a drive pinion gear connected to a servo motor: as the pinion rotates, it engages with the rack’s teeth to convert rotational motion into precise linear movement. This enables accurate positioning, high-speed travel, and strong load capacity in CNC machine axes, making it essential for applications requiring long stroke and high dynamic performance.

Choosing the right linear guide involves determining several key attributes:

1. Load Capacity: Ensure it matches your application's weight and force requirements.
2. Precision: Select based on needed accuracy for positioning and movement.
3. Speed and Acceleration: Choose a guide that supports your operational speeds.
4. Environment: Consider conditions like temperature, dust, and corrosives.
5. Size and Space: Fit within the physical constraints of your machinery.
6. Durability and Life: Look for guides rated for long-term use in your application.
7. Cost: Balance performance needs with budget considerations.

Q: What are the accuracy grades for linear guides? A: Linear guide accuracy grades are generally categorized into five grades: standard, advanced, precision, ultra-precision, and ultra-high precision.24 The specific grade you choose depends on your application requirements.

Q: How do you determine the length of a linear guide? A: The guide rail length should be calculated based on the effective travel of the equipment plus a necessary safety margin. If a protective cover is required, the compressed length of the cover at each end should also be considered.

Q: Can pin holes be machined into the slider and guide rail to eliminate backlash? A: In some cases, pin holes can be machined into the slider and guide rail to eliminate backlash. However, it should be noted that for small-sized guide rails that use through-hardening, later drilling may not be feasible.

Q: Are linear guides self-locking? A: Linear guides do not inherently have a self-locking function, but if self-locking is required, it can be achieved by adding an external self-locking device.

Q: What is the operating temperature range for linear guides? A: Generally speaking, the operating temperature range of linear guides is between -30℃ and 80℃. Prolonged use in high temperature environments may cause material aging or deformation
