⚙️Product Description:
Looking for a reliable supply of highly specialized components for precision robotics joints without facing massive custom manufacturing backlogs? Our Non-Standard FR6ZZ Flanged Deep Groove Ball Bearing features a unique imperial-metric hybrid custom profile (4.384mm x 22.225mm x 7.142mm). Engineered with a specialized custom bore to perfectly match non-standard shafts in robotic arms and automated mechanisms, it features dual metal shields (ZZ) for lifetime lubrication and dust protection. As a versatile B2B bearing partner, we supply this rare-size precision component under our own rigorous “RMO” brand to maximize your cost-efficiency, or leverage our trade supply network to procure specific global premium brands to fit your project requirements.
⚙️Product Features:
- Exclusive Non-Standard Geometry: Features a rare 4.384mm bore paired with a robust 22.225mm outer diameter, solving unique engineering mismatches without extra tooling costs.
- Integral Flanged Design (FR): The precision-engineered outer ring flange allows simplified housing designs and secure axial positioning, preventing displacement under high-vibration robotic arm movements.
- Double Metal Shields (ZZ): Pre-lubricated with high-performance robotic synthetic grease, sealing out fine dust and manufacturing debris while retaining lubricant.
- High-Grade Chrome Steel (GCr15): Both rings and balls are deeply hardened to ensure exceptional radial load capacity, lower friction coefficient, and micro-scale precision longevity.
- Flexible B2B Sourcing Support: Benefit from high profit margins via direct supply of our proprietary RMO brand, or request our global trade division to procure tier-1 international brands.
⚙️Product Application:
Due to its unique customized sizing and heavy-duty tracking capabilities, the non-standard FR6ZZ bearing is widely utilized in:
- Multi-axis robotic arms, cobots (collaborative robots), and custom articulation joints.
- Precision medical scanning equipment drives and laboratory automation tracks.
- Customized linear guide pulleys, wire rope tracking systems, and drone gimbal stabilization.
- High-end RC models, specialized aerospace prototyping, and micro-motor shafting.
- Automated optical inspection (AOI) systems and high-tech semiconductor handling grippers.
⚙️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. |
