Strong Radial Load Capacity: The linear contact between the cylindrical rollers and the raceway enables the RN307M to bear heavy radial loads, which is far superior to deep groove ball bearings in high load working conditions such as mining machinery and industrial motors.
Space-Saving Design: The outer ring free structure simplifies the mechanical assembly. It can be directly matched with the appropriate inner diameter journal to form a supporting structure, which is especially suitable for equipment with limited installation space.
Low Friction & High Efficiency: The precision processed rollers and cage (brass optional) minimize the friction coefficient during operation. It achieves low-noise and low-energy consumption operation while maintaining high speed.

| 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. |
