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.

6002RS Bearing: Precision Sealed Deep Groove Ball Bearings for Demanding Applications

Looking for a dependable 6002RS bearing that handles high speeds and everyday wear without failing prematurely? We've supplied thousands to U.S. importers, machine shops, and OEM lines over the past few years. These are 15x32x9mm deep groove ball bearings with double rubber seals—built for motors, pumps, and conveyor systems where contamination is a real headache.

At YIDI Motion, we don't just stock them. Our Hebei factory runs them on German-imported grinders and Japanese precision assembly lines. Lead times? Typically 7-15 days for bulk, FOB Tianjin. Skip the middlemen and get factory-direct pricing that beats Alibaba spot deals.

Procurement managers in the U.S. often hit snags sourcing small-bore bearings like the 6002RS. Spot market prices fluctuate, quality varies wildly from unknown exporters, and those double-sided rubber seals (2RS) can leak grease if the contact isn't spot-on. We've seen it firsthand—jobs halt when a $2 bearing fails in a spindle or fan motor.

That's where our 6002RS steps in. Standard dimensions: 15mm inner diameter, 32mm outer, 9mm wide. Rated for 4300 RPM dynamic load, 2100 static, with a typical lifespan pushing 20,000 hours under moderate duty. Not hype—these numbers come from real dyno tests we run before shipment.

Back in 2020, when YIDI Motion fired up, we targeted linear motion parts but quickly expanded into bearings because buyers kept asking. Our 100-person team, 30% senior techs, handles everything from SF1 bushing parallels to these sealed balls. Exports to 50+ countries, including steady U.S. routes via LAX and ORD.

One importer from Ohio told us last quarter: "Switched to your 6002RS after Taiwanese seals wore out in three months. Yours held up through a full production run." Simple fix, but it saved them downtime costs.

Let's break it down further. The 6002RS isn't some generic import. It's a 6002 series deep groove, ZZ alternatives but with RS nitrile rubber lips that keep out dust better in washdown environments. Grease? Lithium-based, NLGI 2, good to 120°C continuous.

Buyers compare us to SKF 6002-2RS1 or NSK 6002DDU. Fair enough. Ours match ABEC-3 precision (P6 equivalent), but at 40-60% lower cost for wholesale lots. No compromises on chrome steel (GCr15), heat-treated to 58-62 HRC.

Ever dealt with radial play issues? Ours spec at 8-28 microns max, ensuring quiet operation in stepper motors or RC models—yeah, we supply those too.

Market's shifting. With supply chains tightening post-2022, U.S. ops managers are eyeing China direct more. But risks linger: fake certs, poor tolerances. We counter with ISO 9001 audits, RoHS compliance, and full traceability from billet to pack.

This intro alone scratches the surface. Scroll down for specs, apps, and why factories like ours beat distributors. If you're quoting 1K+ units, hit us up—samples ship free for qualified buyers.

Operations tip: Always pair 6002RS with proper shaft fits (h6/g6). Undersized shafts bind; oversized? Premature wear. We've QA'd returns to spot these mismatches early.

In cross-border trade, MOQs matter. We start at 100pcs for 6002RS, scale to pallets. Container loads? 20-foot fits 150K units, mixed with ball screws or linear guides.

Enough upfront. Time to dive into the details that make procurement decisions easier.

Where 6002RS Bearings Excel in U.S. Operations

These aren't lab curiosities. U.S. buyers slot them into HVAC fans, electric skateboards, 3D printers, and packaging lines. Radial loads up to 560kg handle conveyor idlers fine.

Motors & Pumps: Quiet, sealed for wet environments. Cuts relube needs by half vs. open 6002.
Automotive Aftermarket: Wheel hubs, alternators. Vibration-tested to 10G.
Food Processing: Washdown-rated with FDA-adjacent seals (inquire for cert).
RC & Robotics: High RPM in small frames. Hobby shops reorder monthly.
Linear Motion Pairing: With our SFU ball screws for CNC upgrades.

Contractor note: In dusty shops, RS seals trap grit better than ZZ metal shields. But check for overheat—above 150°C, swap to open or graphited versions.

One Texas fabricator uses 500/month in plasma table spindles. "No more seizing after 6 months," per their ops lead.

Frequently Asked Questions on 6002RS Bearings

What's the difference between 6002RS and 6002ZZ?

RS has rubber contact seals—better dirt exclusion, slight friction drag. ZZ metal shields: faster speed, less protection. Pick RS for contaminated spots.
