⚙️Product Description:
Need to anchor a large 25mm rotating axis within an incredibly tight radial envelope? Our 6705ZZ and 6705-2RS Thin Section Deep Groove Ball Bearings (25x32x4mm) deliver the perfect engineering answer. Featuring a uniquely wide bore relative to its remarkably slim 4mm width, this micro-profile bearing is specifically optimized for hollow-shaft applications requiring expansive internal clearance for wiring or slip rings. As an agile global B2B bearing trader, we provide adaptable procurement models: maximize your cost-efficiency with our proprietary RMO brand factory-direct supply, or utilize our global network to source premium international legacy brands to align with your rigid technical blueprints.
⚙️Product Features:
- Large Bore with Ultra-Slim Profile: Designed with a 25mm inner diameter and 32mm outer diameter, creating an ultra-narrow 3.5mm cross-sectional height that effortlessly solves space-critical design bottlenecks.
- Versatile Shielding Systems: Available as 6705ZZ (Dual Metal Shields) for low-torque, ultra-high-speed operations, or 6705-2RS (Dual Rubber Seals) for superior defense against fine dust and moisture intrusion.
- Premium GCr15 Chrome Steel: Forged from high-carbon chromium bearing steel, ensuring excellent rolling fatigue life, dimensional stability, and high load-bearing performance under continuous rotation.
- Minimized Rotational Inertia: The skeletonized, low-mass design significantly reduces the starting and running torque of your mechanical assemblies, heavily conserving energy in battery-operated motor drives.
- Streamlined Multi-Brand Sourcing: Seamlessly choose between wholesale factory-direct orders of our RMO brand or direct trading channels for specific top-tier global brands to suit diverse market tiers.
⚙️Product Application:
Striking an exceptional balance between an expanded internal diameter and a miniature cross-section, the 6705 series is heavily specified for:
- Industrial automation turntables, rotary tables, and hollow-shaft collaborative robot (cobot) joints.
- Precision optical instruments, laser scanning modules, and large-scale camera gimbal rings.
- Specialized medical imaging gear, laboratory diagnostic arrays, and fluid control hardware.
- High-performance E-bike hub motors, aerospace actuator components, and micro-stepper drives.
- International B2B component distributors and mechanical OEMs searching for non-standard, lightweight precision bearings.
⚙️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. |
