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.

Sourcing Reliable 6200 Bearings: Factory Insights from Hebei YIDI

Procurement teams know the drill when hunting for 6200 bearings. You need that standard deep groove ball bearing—10mm bore, 30mm outer diameter, 9mm wide—that handles everyday loads without drama. We've shipped thousands to operations in the US, Germany, and beyond. At YIDI Motion, we're not just another exporter; our Hebei factory cranks out these workhorses with German and Japanese tooling for consistency that importers count on.

Picture this: your motor assembly line grinds to a halt because a supplier sent undersized shields or noisy open types. Happens more than you'd think in cross-border deals. That's why buyers circle back to us. We get the pain—lead times stretching past 30 days, customs headaches on partial containers, or bearings that seize after 500 hours. Our 6200 stock? Chrome steel GCr15, precision ground, with options like ZZ metal shields or 2RS rubber seals for dusty shop floors.

Over the years, we've learned what sticks in procurement workflows. Engineers want ABEC-1 or P0 tolerances (ISO P0 equivalent), dynamic loads around 5.1 kN, and speeds up to 20,000 rpm greased. Purchasing directors prioritize FOB Qingdao pricing under $1.50 per unit at volume, plus samples that ship DHL in 48 hours. We handle that. Exports to 50+ countries mean we know Incoterms cold—EXW for locals, CIF for US ports like LA or NY.

Let's break it down operationally. A 6200 bearing isn't flashy, but it's the backbone for fractional HP motors, conveyor idlers, and pump housings. Failures often trace to misalignment during install or skipping grease checks. We've seen importers save 15-20% on total cost by switching to our pre-lubed ZZ versions versus cheap stamped alternatives. No hype—just field reports from repeat US clients.

Inside the 6200 Bearing: Engineering Realities

Deep groove ball bearings like the 6200 series trace back to basic radial load designs from SKF's early days. Bore's 10mm ID, perfect for shafting under 1/2 inch. OD at 30mm slots into housings without custom machining. Width? 9mm keeps profiles slim for compact assemblies.

Materials matter here. We use GCr15 chrome steel—52100 equivalent—heat-treated to 58-62 HRC for inner/outer rings. Balls are the same, separated by a pressed steel cage that won't gall under vibration. Tolerances hit P0 standard: radial runout under 7 microns. Not ultra-precision, but solid for 90% of OEM needs.

Load ratings: dynamic Cr at 5.1 kN (1,145 lbf), static Cor 2.39 kN (537 lbf). Grease life? Expect 5,000-10,000 hours at 10,000 rpm, depending on temp. Oil lube pushes higher. Seals make or break it—2RS rubber contacts the ring for grease retention in washdowns; ZZ metal shields suit high-speed spindles.

One operational note: never press-fit without a proper arbor. We've seen rings crack from overzealous installers using sockets. Heat the housing to 80C instead. And preload? Minimal for these; excessive kills life fast.

Compared to 608 or 6300? 6200 bridges small and medium. Cheaper than angular contacts, tougher than sleeve bearings. If noise is an issue, our phenolic cage upgrades quiet things down 3-5 dB.

Where 6200 Bearings Thrive in the Field

Electric Motors: Fractional HP units in fans, blowers, HVAC. Handles axial misalignment better than expected.
Pumps & Compressors: Centrifugal impellers, small reciprocating setups. 2RS seals block coolant splash.
Conveyors: Idler rollers in food processing or parcel sorting. ZZ for dust-prone zones.
Automotive Aftermarket: Alternators, power steering pumps. Vibration tolerance shines.
Appliances: Washers, dryers—spin cycles demand that radial capacity.
Power Tools: Drills, grinders. Compact size fits tight housings.

Contractors tell us these last 2-3x longer than no-name imports in humid US warehouses. One Midwest distributor swapped for our stock after failures in wet environments—downtime dropped.

Smart Procurement for 6200 Bearings: Avoid These Traps

Importers trip up on a few things. First, ignoring seal types—open bearings leak grease in vertical mounts. Second, skimping on vibration testing; cheap cages shed balls under shock loads. Third, forgetting MOQ negotiations. We start at 100 pcs but drop to 50 for samples.

20X42X12Mm Bearing

Ask suppliers these:

What's your radial clearance code (C3 common for interference fits)?
