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.

130 Micro DC Motors: Compact Power for Precision Motion Control

Quick Supplier Specs: High-torque 130-size micro DC motors. 3-12V operation. Up to 15,000 RPM. Custom shaft lengths available. MOQ 100 units. Factory-direct from Hebei YIDI. Get pricing now.

I've been handling exports for micro motors out of our Hebei factory for over eight years now. When procurement teams call about 130 micro DC motors, they're usually dealing with tight spaces and demanding performance specs. These aren't your hobby-grade buzzers. They're workhorses for embedded systems where every millimeter counts.

A 130 micro DC motor refers to the standard 130 frame size—roughly 25mm diameter by 38mm length, depending on the shaft config. Brushed DC design, permanent magnet rotor. Simple, reliable, and cheap to scale. We've shipped thousands to OEMs building robotics kits, medical pumps, and automotive actuators. No fluff here: these motors spin reliably under load, even in dusty shop floors or humid warehouses.

Picture this: your ops manager needs a replacement drive for a conveyor prototype. Off-the-shelf options from big distributors? Often overpriced or under-specced. Lead times stretch to weeks. That's where factory-direct like us steps in. Our line runs on Japanese-imported winding machines, holding tolerances to 0.01mm on armatures. Output? Consistent torque curves that don't wander after 500 hours of run time.

Why the buzz around 130 size specifically? It's the sweet spot. Smaller than N20 or 370 frames for ultra-mini apps, but punches harder than pager motors. Voltage sweet spot at 6-9V for most battery ops. No-load speeds hit 12,000-15,000 RPM easy, with stall torques around 50-80g-cm. Stall current? Peaks at 1.5A, but we gear them down for control.

In cross-border trade, buyers worry about customs hiccups or voltage mismatches. We've learned the hard way—early shipments to the US had regulators frying on 110V test benches. Now, all units ship dual-rated, with clear datasheets matching UL-equivalent standards. Procurement folks appreciate that. No surprises at inspection.

Our factory, YIDI Motion under Hebei Yidi Import & Export, started linear motion parts in 2020 but pivoted into micro drives two years back. Why? Customers kept asking for matched power sources with our ball screws and actuators. Today, 30% senior techs oversee motor assembly. 100-employee team, exporting to 50+ countries. Germany loves our precision; US buyers dig the pricing.

Let's talk real costs. Spot market from AliExpress? Risky quality lottery. European distributors? 3x markup. Us? $1.20-2.50/unit at 1k MOQ, FOB Tianjin. Add DHL for samples—free on qualified inquiries. That's the math procurement directors run.

One importer from Texas shared last month: switched to our 130s after vibration wrecked their drone prototypes. "Held RPM steady through 2G shakes," he said. Operational insight: pair with a simple PWM controller. Keeps heat down, extends brush life to 300+ hours intermittent.

Don't overlook shaft options. D-shaped, threaded, or extended—custom without tooling fees under 5k units. Materials? Pure copper windings, neodymium magnets for punchy startup torque. Housings in engineering plastic or zinc die-cast for IP40+ duty.

Global supply chains being what they are, lead times matter. Standard stock: 7-10 days. Customs rush: 20 days sea to LA port. We've optimized container loads—12k units per 20ft FCL. No air freight premiums needed.

Procurement tip: always spec no-load current under 0.2A. Tells you efficiency upfront. Ours clock 0.15A typical. Saves battery drain in portables.

This intro scratches the surface. We've got engineering samples in hand. Curious about torque curves or gearbox add-ons? Drop an email to adam@yidimotion.com. Let's match your project.

Inside the 130 Micro DC Motor: Engineering Details

Strip one down, and it's straightforward. Core: laminated silicon steel yoke. Armature: skewed commutator slots minimize cogging. Brushes: precious metal alloy for low sparking. Bearings: sintered sleeve, oil-impregnated for 1000-hour L10 life.

Performance varies by wind. Here's a breakdown from our test bench:

Model	Voltage (V)	No-Load RPM	Stall Torque (g-cm)	Efficiency (%)
130-06120	6V	12,000	55	65
130-09150	9V	15,000	75	70
130-12300	12V	18,000	90	68

Customization? Wind for lower KV if high torque needed. Gear ratios 1:10 to 1:100 with metal gears optional. Warning: plastic gears chatter under sustained load—avoid for industrial.

Electrical noise low, thanks to suppressed caps. EMC compliant for CE marking. Temp range: -10°C to 60°C ambient. Exceeds most RC hobby specs.

Dimensions: 25mm OD x 38mm L (body). Shaft 2mm D x 10mm L std.
Weight: 25g nominal.
Mounting: Two M2.5 holes, 15mm spacing.
Leads: 100mm silicone, red/black polarity.

Factory process: auto-winding, laser-welded hooks, dynamic balancing. 100% HI-POT tested at 500V. Reject rate under 0.5%.

Where 130 Micro DC Motors Shine in the Field

Ops teams deploy these in spaces too cramped for steppers. Robotics: arm joints, wheel drives. Medical: insulin pump dosers, lab stirrers. Automotive: HUD actuators, seat adjusters.

One pattern: battery-powered portables. Low quiescent draw means longer runtime. Distributors resell into drone swarms—hundreds per payload.

Industrial angle: vending machines, ticket printers. Continuous duty cycles without burnout. We've seen them in solar trackers, paired with our linear guides for precise panel tilt.

Cross-border sellers on Amazon? Bundle with gearboxes for toy cars. Margins hold at 40% after shipping.

Caution: high-speed apps need thrust bearings. Ours handle 100g axial ok.
