6806 Bearing: Your Go-To Thin Section Deep Groove Solution
Sourcing a dependable 6806 bearing shouldn't mean endless supplier hunts or quality roulette. We've shipped thousands to U.S. operations managers handling spindle drives and automation lines. Inner diameter 30mm, outer 42mm, slim 7mm width—built for where space is tight and speeds hit 20,000 RPM without chatter.

Procurement teams in the U.S. often hit snags when specs like the 6806 bearing call for exact tolerances. This deep groove ball bearing, sized at 30x42x7mm, slots into compact assemblies where every millimeter counts. Factories pushing CNC spindles or servo motors rely on it because it handles radial loads up to 4.55 kN dynamic while keeping noise low.
Over here at YIDI Motion, we've seen importers balk at lead times from sketchy overseas sources. Our Hebei setup cranks these out with Japanese-imported grinders ensuring roundness within microns. No fluff— just steady output for repeat orders. Exporting to over 50 countries means we've dialed in the logistics for pallets landing in New Jersey ports without customs drama.
Why does this matter? A mismatched bearing fails early, spiking downtime on your production floor. We've fielded calls from operations managers mid-shift, scrambling after a cheap import grenaded under load. The 6806 isn't flashy, but its thin-section design—Chrome steel GCr15 construction—delivers ABEC-3 precision as standard, with upgrades to P6 if your application demands it.
Let's break it down operationally. Picture a U.S. automation firm retrofitting robot arms. Space constraints rule out bulkier options like 6006 equivalents. The 6806 fits snug, spins clean at high RPMs, and shrugs off minor misalignment. We've customized cages—steel or nylon—for clients needing oil or grease retention in dusty shops.
Market shifts play in too. With supply chains tightening post-2022, buyers now prioritize factories with vertical integration. YIDI Motion doesn't just assemble; we source rod stock, heat-treat in-house, and test vibration on German Schaeffler-grade equipment. Result? Bearings that outlast generics by maintenance cycles, based on what our U.S. distributors report back.
One importer from Texas shared how switching to our 6806 cut spindle rebuilds from quarterly to annual. Not hype—straight from their uptime logs. If you're quoting projects, factor in the total cost: initial price plus reliability. Ours hover competitive because volume from Europe and Asia keeps margins tight.
Technically, it's a single-row radial bearing per ISO 15 dimensions. Open or sealed variants available—ZZ for metal shields, 2RS for rubber to trap lube in harsh spots. Static load? 2.7 kN. Reference speeds top 20,000 RPM unlubricated, but grease it right and you're good for 15,000 continuous.
We've packed these into 20-foot containers holding 50,000 units, FOB Xingang port. U.S. duties? Classed under HTSUS 8482.10.5012, typically 2.5%—we prep paperwork to smooth CBP clearance. No minimums for samples; bulk starts meaningful at 500 pieces.
Curious about variants? The 6806-2RS thrives in sealed environments like electric motors. For vacuums or cleanrooms, our 6806 LLU with low-torque seals cuts drag. Procurement folks appreciate the drop-in compatibility—no re-engineering needed versus Japanese or European brands.
In procurement workflows, specs sheets are king, but real talk seals deals. We've consulted on swaps from 6906 series when axial loads creep in. Test data shows the 6806 edges out on radial efficiency, especially under 10,000 RPM where heat buildup matters.
YIDI's edge? Senior techs—30% of our 100-person team—tweak processes weekly. Imported grinders from Japan hit Ra 0.1 surface finishes. Exports to Germany demand that level; U.S. buyers get it standard. Phone us at +86 18134111662 for a quick audit of your current supplier's output.
This isn't entry-level advice. We've walked factory floors where misground races led to brinelling after 6 months. Our QCs catch that pre-ship. Bottom line: stable partners beat spot-market gambles every time.
Deep Dive: 6806 Bearing Technical Specifications
Exact dimensions matter when you're dimensioning assemblies. Here's the rundown, pulled from our ISO-compliant drawings.
| Parameter | Value |
|---|---|
| Bearing Number | 6806 (6806ZZ / 6806 2RS) |
| Dimensions (d x D x B) | 30 x 42 x 7 mm |
| Dynamic Load (Cr) | 4.55 kN |
| Static Load (Cor) | 2.70 kN |
| Max Speed (Grease) | 15,000 RPM |
| Material | GCr15 Chrome Steel |
| Precision Class | ABEC-1 / P0 (P6 optional) |
| Weight | 0.032 kg |
Suits most metric setups. Compare to NSK or SKF analogs—interchangeable, but ours test tighter on radial runout. Watch for fakes; measure chamfer radius—should be 0.3mm nominal.
Where 6806 Bearings Excel in Practice
High-speed spindles top the list. U.S. machine shops spin these at 12,000 RPM for PCB drilling. Compact footprint keeps head weight down, boosting acceleration.
- Electric Motors: Armature supports in servo units. Handles imbalance better than angular contacts in radials.
- Robotics: Joint pivots where payload limits rule. Nylon cages quieten servo noise.
- CNC Routers: Z-axis slides. Sealed 2RS versions fend off chips.
- Pumps & Fans: Impeller shafts. Thin profile fits OEM redesigns.
- Medical Devices: Scanner turntables. Low torque variants available.
One caveat: Avoid pure axial loads over 1 kN—pair with thrust bearings. We've seen failures in propeller hubs from overlooked vectors.
Smart Procurement Guide for 6806 Bearings
Distributors chase low bids, but ops directors eye lifecycle. Vet suppliers on heat-treat logs, not brochures. YIDI provides batch certs tracing to raw billet.
- Grease type compatibility—lithium NLGI 2 standard.
- Packing density for air freight—FOB vs CIF quotes.
- Sample policy: Test 10 pieces first.
- Return terms: 30 days for DOA.
Bulk pricing drops at 1,000 units. U.S. importers favor our DDP terms to dodge brokerage hassles. Compare: Spot buys from Alibaba average 20% markup over direct factory.
Installation Realities & Maintenance
Press-fit with arbor tool—never hammer. Heat inner race to 80°C max. Align housing bore to H7 tolerance.
Grease every 2,000 hours or quarterly. Listen for growl—early wear sign. Replace if vibration exceeds 0.08 g.
Logistics note: Pack in VCI bags for ocean transit. We've halved rust claims with this.
