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 Plaguing Your Bearing Supply Chain

You demand precision, but competitors like high-price brands or unreliable Chinese suppliers fall short. Here's why:

High Prices Eating into ROI: Premium Western bearings cost 30-50% more, squeezing your budgets without proportional gains.
Low Quality Leading to Failures: Cheap imports fail prematurely, causing 20% downtime – that's $50,000+ lost per incident in mid-size factories (per IndustryWeek data).
Skyrocketing Shipping Costs: Overseas delays add 15-25% to total costs, with lead times over 45 days disrupting your USA operations.
Inconsistent Service: No customization, poor after-sales – leaving you scrambling during breakdowns.
Supply Chain Vulnerabilities: Reliance on distant sources ignores China's efficient chains, but without quality vetting.
Technical Mismatches: Bearings not optimized for high-speed linear motion in robotics or CNC, reducing efficiency by 25%.

These issues compound: a single bearing failure cascades into production halts. Ready to fix this? Contact YIDI now for a no-obligation assessment.

What Does Bearing Mean? Complete Definition, Types, Specs, and Applications

In the first 100 words: What does bearing mean? A bearing is a mechanical component that supports rotating or linear motion by minimizing friction between moving parts. It enables shafts to rotate freely while handling radial, axial, or combined loads. Essential in industrial manufacturing, bearings ensure efficiency in everything from conveyor systems to precision robotics.

Core Functions of Bearings – What Is a Bearing Used For?

Bearings reduce friction (by up to 50% vs. plain surfaces), support loads, and extend machine life. In engineering, bearing meaning extends to "directional support" – preventing wobble or misalignment.

Radial Loads: Perpendicular to shaft (e.g., weight in motors).
Axial Loads (Thrust): Parallel to shaft (e.g., propeller thrust).
Moment Loads: Tilting forces in heavy machinery.

Types of Bearings Explained – LSI: Ball Bearing, Roller Bearing, and More

Understanding types of bearings is key for selection. Here's a breakdown occupying technical depth:

Type	Description	Dynamic Load (kN)	Static Load (kN)	Max Speed (rpm)	Applications
Deep Groove Ball Bearing	Versatile radial load handler with low friction; steel balls in raceways.	12-60	25-120	20,000	Electric motors, pumps, automotive wheels.
Cylindrical Roller Bearing	High radial capacity; rollers for heavy loads, no axial support.	50-200	100-400	15,000	Gearboxes, rolling mills, wind turbines.
Angular Contact Ball Bearing	Handles combined loads; 15-40° contact angle for thrust.	20-80	40-150	18,000	Machine tools, spindles, pumps.
Thrust Ball Bearing	Axial loads only; washers and balls for one-direction thrust.	N/A	50-300	5,000	Cranes, turntables.
Plain (Bushings)	Sleeve-type; low-speed, high-load with lubrication.	5-50	10-100	2,000	Hinges, agricultural equipment.
Linear Bearings (YIDI Specialty)	Recirculating balls for smooth linear motion.	10-100	20-200	3m/s	CNC, actuators, automation (ties to ball screws).

what is the purpose of bearing type of bearing the bearing
