What Is a Ball Screw and How Does It Work?

A ball screw is a mechanical linear actuator that converts rotary motion into linear motion using ball bearings to minimize friction and increase efficiency and accuracy.

What Types of Ball Screws Do You Offer?

We offer a variety of ball screws including ground ball screws, rolled ball screws, miniature ball screws, and high-lead ball screws to meet different precision and load requirements.

How Do I Choose the Right Ball Screw for My Application?

Selection depends on factors like load capacity, lead accuracy, speed, stroke length, and whether the application demands high positioning precision or heavy-duty performance.

What Is the Difference Between Ground and Rolled Ball Screws?

Ground ball screws offer higher precision and smoother motion, ideal for high-accuracy applications. Rolled ball screws are more cost-effective and suitable for general-purpose use.

What Maintenance Is Required for a Ball Screw?

Regular lubrication is essential. Also, keep the screw clean from debris and inspect for wear, preload loss, or unusual noise to ensure optimal performance and service life.

3 Critical Pain Points When Sourcing MGN12 Linear Rails

Procuring MGN12 linear rails for industrial or CNC applications often hits these roadblocks:

❌ Problem #1: Counterfeit or Low-Quality Rails

40% of buyers report receiving substandard rails that fail under load or wear out prematurely. Many suppliers cut corners on hardness (HRC58-62) or use inferior steel, leading to reduced lifespan and machine downtime.

❌ Problem #2: Long Lead Times & Stock Issues

Hiwin and THK lead times can stretch to 12+ weeks. Smaller suppliers often lack inventory, forcing you to halt production or pay premiums for rush orders.

❌ Problem #3: Hidden Costs in Customization

Need custom lengths, pre-drilling, or black oxide coating? Many manufacturers charge 20-50% extra for modifications, or refuse small MOQs (Minimum Order Quantities).

YIDI Motion solves these:

✅ Certified quality (ISO 9001, RoHS) with 100% hardness testing.
✅ 5000+ rails in stock for 7-day global shipping.
✅ OEM/ODM flexibility—no MOQ for prototypes, bulk discounts for large orders.
