⚙️Product Description:
Developing ultra-compact devices where every millimeter and gram counts? Our 6700ZZ and 6700-2RS Ultra-Thin Section Bearings (10x15x4mm) are the definitive solution for micro-mechanical designs. Featuring an incredibly slim 2.5mm cross-section, this miniature bearing drastically reduces the overall weight and spatial requirements of your assemblies without sacrificing rotational precision. Whether you need the frictionless high-speed performance of the metal-shielded (ZZ) version or the robust dust/water resistance of the rubber-sealed (2RS) variant, we have you covered. Operating as a flexible global B2B trader, we proudly supply our high-margin RMO brand factory-direct, while also fulfilling custom requests for tier-1 international bearing brands to match your exact OEM specifications.

⚙️Product Features:
- Ultra-Miniature Geometry: Measuring just 10mm (ID) x 15mm (OD) x 4mm (Width), it offers one of the lowest cross-sectional profiles available, perfect for hollow shafts and micro-housings.
- ZZ & 2RS Shielding Options: Choose 6700ZZ (Dual Metal Shields) for maximum RPMs and minimal friction, or 6700-2RS (Dual Rubber Seals) for superior protection against moisture and micro-debris in harsh environments.
- Premium Chrome Steel (GCr15): Manufactured from high-carbon chrome steel, ensuring exceptional hardness, fatigue resistance, and a longer lifecycle under continuous high-speed rotation.
- ABEC Precision Grinding: Finely ground raceways and perfectly matched steel balls result in whisper-quiet operation, low vibration, and superior dynamic stability.
- Strategic B2B Sourcing: Optimize your procurement strategy. Leverage our RMO brand for massive cost savings on bulk production runs, or utilize our sourcing channels for specific global legacy brands.
⚙️Product Application:
Designed for mechanisms requiring high precision within microscopic envelopes, the 6700 series is heavily utilized in:
- Camera gimbals, drone (UAV) brushless motors, and precision optical stabilizers.
- High-end RC (Radio Control) cars, helicopters, and hobbyist model gearboxes.
- Miniature robotics, micro-actuators, and compact stepper motors.
- Dental handpieces, portable medical diagnostic tools, and lab centrifuges.
- B2B hardware importers and tech-hardware OEMs seeking reliable ultra-thin components.
⚙️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. |
