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.

The 6 Hidden Costs of Poor Linear Actuator Choices

In 2025, 73% of industrial buyers reported actuator failures causing unplanned downtime (source: Machine Design Magazine). When purchasing electric linear actuators, most buyers focus solely on upfront price — but the real costs emerge months later:

Industry Data Point:

Actuators account for 12% of total machinery maintenance budgets in high-cycle applications (per IFR Industrial Robotics Report 2026)

1. Energy Waste from Inefficient Motors

Standard actuators waste 25-35% energy in standby mode. Our IE3-rated motors cut power consumption by 40%.

Real case: German automotive supplier reduced annual energy costs by €8,200

2. Customs Delays from Non-Compliant Products

40% of actuator imports get held at customs due to missing CE/FCC certifications. Our complete documentation package prevents 95% of clearance issues.

Tip: Always verify RoHS compliance before ordering

3. Hidden Shipping Costs

Air freight for replacement actuators costs 3-5× more than ocean freight. Our 12-week buffer stock ensures 98% on-time delivery.

Calculation: $2,400 vs $850 for 50kg shipment

⚡ Quick Win: Our patented heat dissipation design extends service life by 2×

Why Our Electric Linear Actuators Deliver 30% Faster ROI

Factory-Direct Advantage

✓ 30% cost reduction via integrated manufacturing (no middleman markup)
✓ 7-day prototype turnaround for OEM orders (industry avg: 21 days)
✓ 50+ standard models with custom stroke lengths (100mm-2000mm)

Engineered for Your Industry

✓ IP65/IP67 rated for washdown environments (food/pharma)
