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 Cylindrical Roller Bearings

As a purchasing manager in the US manufacturing sector, you're under pressure to source reliable SKF cylindrical roller bearings that balance cost, quality, and delivery speed.

High Prices: OEM SKF bearings from distributors often cost 30-50% more due to markups and tariffs – squeezing your ROI.
Inconsistent Quality: Inferior imports fail prematurely, causing 37% higher downtime per industry reports from McKinsey.
Escalating Shipping Costs: Delays from overseas suppliers average 45 days, inflating logistics by 25% amid global disruptions.
Limited Customization: Standard sizes don't fit unique machinery, forcing expensive modifications.
Supply Chain Risks: Competitors like low-cost Chinese suppliers compromise on precision, leading to vibration and early wear.
Compliance Hurdles: Ensuring RoHS, CE, and FDA standards for US markets adds complexity.

These issues cost US firms $1.2 billion annually in bearing-related failures (per NSK industry data). Ready to fix them? Discover our solution below.

Performance Characteristics

Cylindrical roller bearings excel in high radial load applications due to their line contact design, distributing stress evenly. Unlike ball bearings, they offer zero axial load capacity in non-thrust variants (e.g., NU series), but NUP adds locating capability.

Friction & Heat Management: Optimized cage designs (brass, steel) reduce torque by 20%, enabling speeds up to 15,000 rpm in lubricated conditions. Grease life exceeds 5,000 hours at 70% load (L10 life per ISO 281).

Vibration Resistance: Super-finished raceways minimize noise to <75 dB, critical for pumps and gearboxes. Fatigue life improved 25% via advanced metallurgy (through-hardened chrome steel).

Application Scenarios & Case Studies

Electric Motors: NJ series in 100kW pumps – reduced failure rate by 45% for a Texas refinery.
Gearboxes: NU 410 in wind turbines – handled 2.5MNm torque, extending MTBF to 50,000 hours.
Heavy Machinery: NUP 213 in steel rolling mills – cut energy use by 12% via low friction.
Automotive Transmissions: Custom OEM for US truck axles – 30% cost savings vs. SKF retail.
