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.

Sourcing Challenges: Why HGR20 Linear Rails Frustrate US Buyers

As a Operations Manager in the USA manufacturing sector, you're under pressure to optimize linear motion systems without breaking the budget. But here's the reality:

High Prices: Competitors charge 20-40% premiums due to middlemen and import tariffs, eating into your ROI.
Low Quality Issues: Cheap knockoffs from unverified suppliers fail prematurely, causing 37% more downtime per industry reports from Automation World (2025).
Skyrocketing Shipping Costs: Delays of 4-6 weeks and fees up to $500 per pallet from distant suppliers disrupt your production lines.
Inconsistent Supply Chains: China's fragmented suppliers lead to mismatched specs, voiding warranties on your CNC or robotic arms.
Lack of Customization: No OEM/ODM options mean retrofitting, adding 15-25% to total costs.
Compliance Headaches: Missing CE/RoHS certs block FDA-regulated or UL-listed applications in the US.

These issues compound, with 68% of US buyers reporting supplier switches in the last year (per McKinsey Supply Chain Survey 2026). Ready to fix this? Scroll to our solutions.

Detailed Technical Specifications – HGR20 Linear Rail

Our HGR20 rails dominate one-third of linear guide applications in automation. Below is a comprehensive spec table for easy integration into your CAD systems. (Compliant with US standards: RoHS, CE, ISO 9001).

Model	Width (mm)	Height (mm)	Dynamic Load (C) kN	Static Load (C0) kN	Accuracy Grade
HGR20	20	17.25 (Block)	28.1	27.5	C0 (Normal), H (Light), P (Medium), SP (Heavy), UP (Super Heavy)
Block Length Options	45 / 60 / 70 / 90 / 105 / 120 / 150mm	Friction Coefficient	0.003	Max Travel Length	4,000mm (custom)
Preload	ZP (Light), Z0 (Medium)	Dust Protection	SS (Standard)	Operating Temp	0-80°C

Performance Characteristics: HGR20 excels in high rigidity (4-row ball circulation), low noise (<65dB at 2m/s), and vibration resistance. Rigidity formula: K = 120 N/μm (X/Y/Z directions). In tests, it handles 5G accelerations without deflection.

Real-World Applications & Case Studies

HGR20 is the backbone of linear motion components in:

CNC Machines: 3-axis mills achieving 50m/min rapids – Case: US fabricator reduced setup time by 25% with our matched sets.
