⚙️Product Description:

Equipping a 30mm structural shaft that operates in unforgiving outdoor or heavy-impact environments? The 6906-2RS and 6906ZZ Deep Groove Bearings (30x47x9mm) deliver the perfect balance of radial compactness and rugged endurance. Featuring a versatile 30mm bore paired with a solid 9mm width, this bearing excels at absorbing the sudden shocks and lateral forces that frequently shatter ultra-thin alternatives. It is the uncompromising mechanical core for motorcycle wheel hubs, heavy-duty mining conveyor rollers, and robust agricultural machinery. Operating as an elite B2B bearing trading enterprise, we execute a dual-tier supply strategy: drive down your manufacturing costs with bulk pallets of our aggressively tested RMO proprietary brand, or task us to source authentic, heavy-duty international legacy brands for your most stringent OEM equipment audits.

6906 bearings

⚙️Product Features:

30mm Impact-Optimized Geometry: The 30x47x9mm dimension provides a substantial raceway depth and larger rolling elements, granting the bearing an exceptional ~7,250 N dynamic load capacity to easily manage the drop-shocks of motorcycle suspensions.
Severe Environment Sealing: Deploy the 6906-2RS (Rubber Seals) to form an impenetrable barrier against mud, crop residue, and rainwater in outdoor agricultural planters; or utilize the 6906ZZ (Metal Shields) for fast-spinning indoor packaging rollers.
Lateral Force Resistance: The 9mm cross-section drastically improves stiffness against off-axis twisting, which is critical for steering stem applications and unevenly loaded conveyor belts.
Heavy-Duty GCr15 Metallurgy: Forged from premium 52100 high-carbon chrome steel to prevent raceway spalling and metal fatigue when subjected to the relentless vibrations of material handling equipment.
Scalable B2B Procurement: We synchronize with your production rhythm. Supply your aftermarket network with highly profitable RMO inventory, or integrate specific top-tier global brands directly into your OEM factory lines.

⚙️Product Application:

Engineered for environments where resilience matters as much as smooth rotation, the 6906 series is vital for:

Motorcycle front/rear wheel hubs, steering stems, and ATV suspension linkages.
Industrial conveyor belt rollers, mining idlers, and material handling systems.
Agricultural machinery (seeders, harvesters, disc harrows) operating in muddy terrain.
Heavy-duty industrial power tools, rotary hammers, and large concrete mixers.
Global motorcycle parts wholesalers and heavy-machinery component importers.

⚙️Precautions:

1. Keep clean	2. Use with caution	3. appropriate tool	4. Hot-loading	5. Be careful of rust
Dust will have a bad effect on the bearing, so keep the surrounding clean.	Strong impact during use can easily cause scratches and indentations.	Avoid replacing existing tools, and use appropriate tools.	Bearings are precision parts, so hot installation is recommended.	Sweat on your hands during operation will cause rust, so it is best to wear gloves.
