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.

Struggling with the Wrong Types of Rolling Bearings? Here's Why It's Costing You

You know the drill: machinery breakdowns, unexpected downtime, and suppliers who promise the world but deliver headaches. In 2026, with USA manufacturing ramping up amid supply chain volatility, choosing the right types of rolling bearings is critical.

High Prices Eating into ROI: Premium brands charge 30-50% more, yet competitors undercut with low-quality imports that fail prematurely.
Poor Quality Leading to Failures: Mismatched bearings cause 25% of industrial equipment seizures, per recent McKinsey reports – think vibration, overheating, and seized shafts.
High Shipping Costs & Delays: Overseas orders from unreliable Chinese supply chains add $5K+ in freight and wait 8-12 weeks, disrupting your operations.
Lack of Customization: Off-the-shelf options don't fit high-precision needs in automation or heavy machinery.
Compliance Nightmares: Navigating USA regs like RoHS and FDA for food-grade apps is a minefield without certified partners.
No Reliable Support: Post-sale service? Forget it – leaving you scrambling during peak production.

Master Types of Rolling Bearings: Specs, Applications & Why YIDI Excels

At YIDI Motion, established in 2020, we specialize in ball bearings, roller bearings, and more – all from our 100-employee factory with 30% senior technicians. Imported German/Japanese equipment ensures precision. Here's your guide to key types of rolling bearings for industrial machinery, backed by data.

Rolling bearings reduce friction via rolling elements (balls or rollers) between races. They outperform plain bearings by 40% in speed and handle radial/axial loads efficiently.

1. Ball Bearings: Versatile for High-Speed Apps

Deep groove ball bearings are the workhorse – ideal for electric motors, pumps. Self-aligning variants handle misalignment up to 3°.

Type	Bore Dia (mm)	Dynamic Load (kN)	Max Speed (RPM)	Apps
Deep Groove	10-200	5-150	20,000	Motors, Fans
Angular Contact	10-150	10-200	15,000	Machine Tools

2. Roller Bearings: Heavy-Duty Load Kings

Cylindrical rollers excel in radial loads; tapered for combined loads in gearboxes. Needle rollers save space in transmissions.

Type	Bore Dia (mm)	Dynamic Load (kN)	Max Speed (RPM)	Apps
Cylindrical	20-500	50-1000	10,000	Conveyors
Tapered	15-300	100-800	8,000	Automotive Axles
Spherical	20-400	200-1500	6,000	Mining Equipment
Needle	3-140	10-100	12,000	Gearboxes

These specs are from ISO 281 standards; our bearings exceed by 15% in fatigue life due to premium chrome steel and heat treatment up to HRC 62.
