Linear Motion Components

Q: What is the difference between ball and roller linear guides?

Ball-type guides offer lower friction for high-speed applications. Roller-type guides provide higher load capacity and rigidity for heavy cutting forces.

Q: What accuracy grade of ball screw do I need?

For general positioning, rolled C7 is cost-effective. For CNC machine tools and precision measurement, precision ground C5 or C3 screws are recommended.

Q: Can you provide pre-assembled linear motor axes?

Yes. We offer integrated linear motor stages including coil, magnet track, encoder, and cable management for simplified integration.

Q: How do I select the correct preload for a linear guide or ball screw?

Light preload is standard. Medium or heavy preload is used where maximum stiffness is required. Our engineers can help select based on your application needs.

Frequently Asked Questions

What is the difference between ball and roller linear guides?

Ball-type guides offer lower friction and are suitable for high-speed, moderate-load applications. Roller-type guides provide significantly higher load capacity and rigidity, making them ideal for heavy cutting forces in machine tools or injection molding platens.

What accuracy grade of ball screw do I need?

For general positioning and material handling, rolled C7 ball screws are cost-effective. For CNC machine tools and precision measurement, we recommend precision ground C5 or C3 screws, which offer much tighter lead accuracy and repeatability.

Can you provide pre-assembled linear motor axes?

Yes. We offer integrated linear motor stages that include the motor coil, magnet track, linear encoder, and cable management. These ready-to-install axes simplify integration and ensure optimal alignment for high-performance motion.

Do you offer custom ball screw end machining?

Absolutely. We provide custom end machining services to match your bearing journals and coupling requirements. Please supply a drawing specifying diameters, thread details, and shoulder lengths, and we will machine the screw ends to your exact specifications.

How do I select the correct preload for a linear guide or ball screw?

Light preload is standard for most applications, providing good rigidity with minimal friction. Medium or heavy preload is used in high-vibration environments or where maximum stiffness is required. Our application engineers can assist in selecting the optimal preload class based on your load and accuracy requirements.
