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.

6002 Bearing Dimensions: Engineering Specs and Procurement Essentials

Sourcing the right deep groove ball bearing starts with nailing the dimensions. The 6002—15mm bore, 32mm OD, 9mm width—is a workhorse in motors, pumps, and machinery. We've shipped thousands to US buyers. Avoid undersized failures or overkill costs.

Procurement managers hit roadblocks when bearing specs don't match OEM drawings. The 6002 bearing dimension query spikes because it's a standard metric size that fits countless setups—from small electric motors to conveyor systems. At YIDI Motion, we've fielded calls from US importers frustrated by inconsistent tolerances from low-tier suppliers.

Picture this: you're retrofitting a pump assembly. Inner diameter needs to be exactly 15mm for the shaft press-fit. Outer at 32mm to clear the housing. And that slim 9mm width keeps the stack compact. Get it wrong, and vibration kicks in early, leading to downtime. We've seen it happen.

Our factory in Hebei churns out these bearings with GCr15 chrome steel—hardened to 58-62 HRC for durability. Not some mystery alloy. We pull from German and Japanese grinding machines, hitting ABEC-3 precision or better on request. Export volumes to North America? Steady since 2020, with repeat orders from machine shops in Ohio and California.

Why does dimension matter so much? Bearings fail 70% of the time from misalignment or sizing errors, per field reports. The 6002's design—deep groove, single row—handles radial loads up to 4.5kN dynamic. But only if dimensions hold. Tolerates minor axial too, which saves headaches in misaligned apps.

Importers often overlook chamfer sizes. On the 6002, it's 0.6mm inner, 0.6mm outer. Critical for seal installation without nicking. We've customized these for OEMs adding rubber seals or snap rings. MOQ starts low—500pcs for standard, drops for long-term.

Market shifts hit hard lately. Steel prices up 20% in China, but we lock supplier contracts to keep 6002 pricing stable. US buyers appreciate that. Compare to SKF or NSK retail—our wholesale beats it by 40-60% on volume. No middlemen.

One engineer from Texas shared how swapping to our 6002 cut his prototype costs. "Exact dims, no slop," he said. That's the feedback loop we live by. Dive into the specs below. Or skip to procurement tips if you're in a rush.

Logistics from Shijiazhuang? 25 days sea to LA port. Air for urgent—7 days. We handle consolidation if mixing with ball screws or linear guides from our lineup.

This isn't fluff. It's what we've learned shipping 50+ countries. Germany demands DIN 620 compliance. US wants ASTM vibes. We cover it. Let's break down the numbers next.

Real-World Applications for 6002 Bearings

Electric motors dominate. Fractional HP units in appliances, fans. The compact dims fit stator housings perfectly. We've supplied lines for US HVAC assemblers.

Pumps next. Centrifugal models where radial loads peak. Tolerates dirty water if shielded.
