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.

Your Biggest Challenges with Spline on Shaft Sourcing

As a purchasing manager in the USA, you face relentless pressure to optimize supply chains. But subpar spline on shaft components derail your operations.

High Prices: Competitors charge up to 25% more without matching quality, eroding your ROI.
Low Quality: Inferior splines lead to 45% failure rates in high-load apps, per industry reports from AMT.
Skyrocketing Shipping Costs: Delays from unreliable Chinese suppliers add $5K+ per order in expedited freight.
Inconsistent Specs: Off-the-shelf splines mismatch your CNC or robotic needs, causing redesigns.
Poor Customization: No OEM/ODM flexibility means extra tooling costs and months of wait.
Compliance Headaches: Missing CE/RoHS certs block FDA-regulated machinery imports.

These issues compound: a single spline failure can halt production for 48 hours, costing $12,000/hour in lost output. Ready for a fix? Explore our solutions below.

spline shaft shaft spline splined shaft

Materials: High-carbon chrome bearing steel (SCM440), hardened to HRC 58-62. Friction Coefficient: <0.003 under greased conditions. Max Speed: 3m/s. Torque Capacity: Up to 500Nm for BSK32, ideal for rotational-linear motion.

Spline Shaft Design & Performance Characteristics

The spline on shaft features Gothic-arch grooves for multi-axis ball contact, distributing loads evenly. This design (per ISO 286 standards) minimizes backlash to 3μm and boosts rigidity by 40% vs. traditional splines.

Spline Profile: Involute with 40° pressure angle; nut integrates circulating balls for zero-slip torque transmission. Preload options (light/medium/heavy) tailor to your app—e.g., heavy for pick-and-place robots enduring 50G acceleration.

Performance Data: In 1 million cycle tests (ASTM F2886), our splines show <1% wear. Vibration damping reduces noise by 25dB, per NSK benchmarks. Heat-treated shafts resist corrosion (salt spray test: 500hrs).

Application Scenarios & Case Studies

CNC Machines: BSK20 spline enables 5-axis milling with 0.01mm repeatability, cutting cycle times by 28% for a Texas fabricator.
Robotics: High-torque BSK25 in SCARA arms handles 15kg payloads at 2m/s, used by a California automation firm.
Medical Devices: FDA-compliant BSK16 for surgical robots, sterile packaging included.
Packaging Lines: Custom OEM spline reduced jams by 35%, saving $150K/year for a Midwest packer.
