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 US Manufacturers Face with Sprag Bearings

As a purchasing manager in the USA industrial sector, you know the frustration. Traditional sprag bearing suppliers often fall short, leading to costly disruptions.

1. Skyrocketing Prices Without Performance Gains

Premium brands charge 40-60% more for sprag bearings, yet deliver marginal torque improvements. Data from Machinery Lubrication reports shows average cost per unit at $150+, eroding your ROI.

2. Unreliable Quality & Frequent Failures

Low-grade sprag clutches seize prematurely under high-speed operations, causing 25% unplanned downtime per Thomasnet surveys. Your operations grind to a halt.

3. Prohibitive Shipping Costs & Delays

Imports from distant suppliers add $50-100 per unit in freight, with lead times stretching 8-12 weeks. In 2026's fast-paced market, this kills competitiveness.

4. Lack of Customization for US Standards

Off-the-shelf sprag bearings rarely match ANSI/AGMA specs, forcing costly modifications.

Comprehensive Sprag Bearing Technical Specifications

Sprag bearings (also known as sprag clutches or one-way bearings) are precision devices using wedging sprags for high-torque overrunning in one direction while locking instantly in the opposite. Ideal for backstopping, indexing, and speed switching in industrial applications.

Key performance characteristics include torque capacities up to 50,000 Nm, operational speeds exceeding 10,000 RPM, and lifetimes over 10,000 hours under load. Our sprags use high-carbon chrome steel with phosphate coating for corrosion resistance in harsh USA environments.

Model	Bore Dia (mm)	OD (mm)	Torque Capacity (Nm)	Max Speed (RPM)	Weight (kg)
YD-SPRAG-10	10	22	15	12,000	0.05
YD-SPRAG-20	20	35	85	10,000	0.12
YD-SPRAG-30	30	47	250	8,500	0.25
YD-SPRAG-50	50	72	850	6,000	0.65
YD-SPRAG-80	80	110	2,500	4,500	1.8
YD-SPRAG-120	120	150	8,000	3,000	4.2

Customization Options: Adjustable drag torque, integrated bearings, special lubrication for high-temp USA ops (up to 200°C). All models RoHS/REACH compliant.

Sprag geometry ensures <0.1° slip angle for precise locking. Overrunning efficiency >99%, with radial load support up to 50% of torque rating.
