⚙️Product Description:
The 6900 series (10x22x6mm) is an extra-light, thin-section deep groove ball bearing specifically developed for applications constrained by strict spatial and weight limits. Featuring a slim cross-section profile that pairs a 10mm bore with a compact 22mm outer diameter and 6mm width, this bearing delivers high rotational speed and low frictional torque without compromising load integrity. Available with low-friction metal shields (6900ZZ) or protective rubber contact seals (6900-2RS), we supply these high-efficiency thin-section bearings under our proprietary RMO brand, supported by versatile multi-brand OEM procurement for global precision equipment manufacturers.
⚙️Product Features:
- Ultra-Compact Thin-Section Profile: Minimizes radial space requirements, enabling engineers to downsize machinery housings and reduce overall system weight significantly.
- Low Rolling Resistance: Precision-ground raceways and optimized ball complement reduce starting and running torque, enhancing energy efficiency in battery-powered electronics.
- Dual Protection Variants: Select 6900ZZ with steel shields for high-RPM operation, or 6900-2RS with contact rubber seals for superior water and dust defense.
- High Load Capacity per Weight Ratio: Premium GCr15 chrome steel construction ensures robust radial support despite the ultra-narrow ring wall thickness.
⚙️Product Applications:
Engineered for lightweight agility and tight spatial integration, the 6900-2RS/6900ZZ bearing is extensively used in:
- Bicycle components: high-end front hubs, rear suspension pivots, bottom brackets, and pedals.
- Aerospace & drones: brushless motor rotors, UAV gimbal camera stabilizers, and servo actuators.
- Medical & dental instruments: handheld optical readers, micro pumps, and diagnostic equipment.
- Robotics & automation: joint reduction gearboxes, optical encoders, and small power tools.
⚙️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. |
