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.

Common Pain Points with Linear Guide Blocks in US Manufacturing

As a purchasing manager, you face relentless pressure to optimize operations. But subpar linear guides amplify issues.

High Prices: Imported blocks cost 20-40% more from premium brands, eroding your ROI.
Low Quality: Cheap alternatives fail prematurely, causing 15-25% unplanned downtime per industry reports from AMT.
High Shipping Costs: Slow ocean freight from Asia adds $500-2000 per pallet and weeks of delay.
Inconsistent Performance: Variable preload leads to vibration in high-speed CNC, reducing precision by up to 0.05mm.
Supply Chain Risks: Competitors' stockouts halt production lines, costing $10K/hour in lost output.
Limited Customization: Off-the-shelf blocks don't match your OEM needs for robotics or automation.

These issues hit your bottom line hard. Imagine slashing them with a reliable HGW 20 CC ZA C block.

HGW 20 CC ZA C Block: Comprehensive Technical Parameters

The HGW 20 CC ZA C block is a flange-type, medium-load linear guide block designed for 20mm wide rails. Its "CC" denotes compact equal length for balanced load distribution, "ZA" indicates light preload (0.08C) for smooth, low-friction motion, and "C" specifies the carriage configuration. Ideal for automation where precision meets affordability.

Key Performance Characteristics:

Dynamic Load Rating (C): 19.8 kN – Handles 20% higher speeds than HG series.
Static Load Rating (C0): 30.2 kN – Superior rigidity under heavy moments.
Pitch Accuracy: ±0.003mm/300mm – Ensures micron-level repeatability in CNC.
Friction Coefficient: 0.003 max with grease lubrication.
Max Speed: 150 m/min; Acceleration: 1.5G.
Operating Temp: -10°C to 80°C; Dust-proof to IP65.

These specs ensure 37% cost reduction over 3 years via extended L10 life (50,000km at 2m/s). Tested per ISO standards.

Performance Characteristics in Depth

The block's 4-row circular-arc contact design yields 45° contact angle for even load distribution, minimizing elastic deformation. Under 10m/s² acceleration, deflection is <0.01mm. Lubrication intervals: 5000km with our lithium grease.

In vibration tests (per ASTM), it outperforms generics by 25% in fatigue resistance. For USA compliance, materials are RoHS-free of Pb/Cd.
