⚙️Product description:
RN309M is a single-row cylindrical roller bearing with an outer ring-free structure, specifically designed for industrial heavy-duty scenarios. Boasting high load-carrying capacity, low friction loss, and stable operating performance, it is widely applied in core mechanical components such as reducers, motors, and machine tools. It serves as a cost-effective choice for industrial manufacturing, equipment maintenance, engineering supporting, and other related fields.

Heavy Load Capacity Advantage: Line contact design between rollers and raceways enables a radial dynamic load capacity of 71.7KN and static load capacity of 47.7KN, far exceeding ordinary ball bearings. It easily handles heavy-duty scenarios such as reducers and gearboxes.
Space-Saving & Easy Assembly: Outer ring-free structure simplifies mechanical design, allowing direct coordination with journals of matching inner diameters to form supports. Particularly suitable for equipment with limited installation space.
Efficient & Low-Noise Operation: Precisely machined rollers paired with brass cages ensure low friction coefficient and minimal operating noise. The speed reaches up to 5600r/min with grease lubrication and 7000r/min with oil lubrication.

⚙️Typical Applications:
| 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. |
