5207 2RS Bearing – Double Row Angular Contact for Heavy-Duty Precision
Sourcing the right 5207 2RS bearing shouldn't mean chasing unreliable suppliers or dealing with inconsistent quality. At YIDI Motion, we've shipped thousands to operations across the US, Europe, and Asia. Get specs, pricing, and samples direct from our Hebei factory.
Quick Navigation
Why Bearing Procurement Goes Wrong – And How to Avoid It
I've seen it too many times. A purchasing manager orders 5207 2RS bearings from a cut-rate overseas listing, only to find the seals fail after a few months in the press or conveyor. Lead times stretch from weeks to months. Suddenly, your downtime costs spike.
Common pitfalls? Unverified suppliers quoting rock-bottom prices but skimping on steel quality. No contact seals mean contaminants sneak in, accelerating wear. Or mismatched tolerances that bind under load. In high-volume ops like yours, this isn't just annoying – it's a balance sheet killer.
Take angular contact bearings like the 5207 2RS. They're designed for combined radial and axial loads in machine tools or pumps. Get the preload wrong or seals that don't hold grease? Expect premature fatigue. We've consulted on fixes where clients swapped cheap imports for our spec-matched units and cut failures by half in the first year.
Another headache: logistics. Spot market buys from unproven exporters lead to partial shipments or customs holds. Container delays from China to US ports? Add 4-6 weeks if paperwork's off. Procurement teams waste hours chasing updates.
Short story: Last quarter, a Midwest fabricator called us after burning through three suppliers. Their 5207 2RS stock was inconsistent – some ran hot, others seized. We audited their needs, shipped samples overnight air, and locked in volume pricing. Production stabilized overnight.
Want to sidestep this? Vet for ISO 9001 certs, real factory tours via video, and proven export records to your region. Test samples under your load conditions. And always factor in total landed cost, not just unit price.
Our 5207 2RS Bearing: Built for Reliability in Demanding Setups
At YIDI Motion, the 5207 2RS isn't just another SKU. It's a double-row angular contact ball bearing with nitrile rubber seals on both sides (2RS), precision-ground from GCr15 chrome steel. Bore 35mm, OD 72mm, width 27mm. Rated for 23.5 kN dynamic load, 18.3 kN static.
What sets it apart? Contact angle of 25 degrees handles thrust like a champ without separating under preload. Seals keep grease in and dirt out – critical for dusty shop floors or washdown environments. We've optimized the cage for low noise and vibration, which matters in precision spindles.
Compared to open 5207 or basic single-seal versions, the 2RS cuts maintenance intervals. No relubrication needed for years in moderate speeds up to 7500 RPM. And our heat treatment hits ABEC-3P tolerances consistently – no lottery on quality per batch.
Buyers often ask about alternatives. SKF or NSK equivalents run premium, but our OEM line matches at 40-60% less. Direct from factory means no middleman markup. We've tooled these for US importers reselling under private label.

These specs aren't pulled from thin air. Tested on our German-imported grinders and Japanese spectrometers for alloy purity. Every lot gets vibration analysis – under 0.5 microns runout typical.
For OEM runs, we match your print tolerances. Added polyamide cages for corrosive environments? No problem. Minimum order 100pcs, but samples ship same week.
Where the 5207 2RS Shines – From Pumps to Presses
Angular contact like this handles misalignment better than deep groove types. Common in agricultural gearboxes, where axial thrust from helical gears eats lesser bearings.
- Textile machinery spindles – steady at high RPMs.
- Hydraulic pumps – resists side loads.
- Conveyor idlers – sealed against grit.
- Metalworking lathes – preload for zero backlash.
- EV motor assemblies – compact thrust support.
One client in Texas runs them in oilfield pumps. Harsh vibration, saltwater exposure. Our 2RS seals held up where competitors leaked after 800 hours.
Not ideal for pure radial loads – use 6207-2RS there. But for combined? Spot on.

Installation and Maintenance Realities
Press-fit with care – use induction heater, not torch. Target interference 0.01-0.02mm on shaft. Align rows parallel; preload via nut to 1-2% deflection.
Grease with lithium complex NLGI 2. Run-in at 50% speed first hour. Monitor temp – over 80C? Check alignment.
Maintenance? Inspect seals yearly. Replace at 5000 hours or vibration rise. In wet apps, annual rinse advised.
What Buyers Say About Our 5207 2RS
John M., Texas Fabricator: "Switched after two bad batches from Alibaba. YIDI's held 2000 hours no issues. Pricing beat Timken quote. Fast air samples sealed the deal."
Maria L., Ontario Importer: "OEM run for our brand. Consistent bore sizes, no rejects. Shipping to Toronto was smooth – full pallet intact."
Raj P., Mumbai Machinery: "Used in spindle rebuilds. Low noise beats local suppliers. Video factory tour built trust."
Mike S., Ohio Plant Manager: "Downtime dropped. Seals don't weep grease like others. Worth the direct import."
Frequently Asked Questions on 5207 2RS Bearings
What's the difference between 5207 2RS and 5207 ZZ?
2RS uses rubber seals – better for contaminated areas, lower friction. ZZ metal shields for high speeds, but less protection.
Can I get these in stainless?
Yes, for food/pharma. AISI 440C, but lead time +20%. Quote required.
MOQ and pricing?
100pcs start. Bulk 500+ drops 15-25%. Email for tiered quote.
Shipping to USA?
Sea 25-35 days door-to-door. Air 7-10 days. DDP options available.
OEM customization?
Full service – logos, packaging, specs tweak. Past clients: pumps, ag equip.
Logistics from China to Your Door
FOB Xingang. 20ft holds 4500pcs packed 10/box, foam protected. Duties? Bearings 4.5% US MFN. We handle docs.
Tracking via Maersk/CMA. Incoterms flexible. Past shipments: LA port 28 days average.
