⚙️Product Description:
The RN206 (including the high-capacity RN206EM variant) is a specialized single-row cylindrical roller bearing engineered without an outer ring. Featuring a 30 mm bore diameter, a 53.5 mm roller assembly outer diameter, and a 16 mm width, its precision rollers run directly against the housing bore. Designed with double integral ribs on the inner ring, this compact unit delivers exceptionally high radial capacity while minimizing radial space requirements. We provide factory-direct inventory of our proprietary RMO brand RN206 bearings with solid brass or steel cage options, alongside premium international brand sourcing for planetary gearboxes, hydraulic pumps, and compact mechanical drives.
⚙️Product Features:
- Outer-Ringless Compact Design: Direct contact between precision rollers and the housing bore eliminates the outer ring, reducing radial weight and structural envelope size.
- Double-Ribbed Inner Ring Guidance: Two integral inner ring flanges ensure strict axial roller guidance and prevent cage tilting during high-speed rotation.
- Heavy-Duty Brass Cage Option (EM): High-strength machined brass cage provides superior resistance to mechanical shock, vibration, and thermal expansion in continuous duty.
- Crown-Profiled GCr15 Rollers: Optimally profiled chromium steel rollers eliminate edge stress concentration under heavy radial loading.
- Flexible Dual-Track Supply: Direct factory supply of RMO brand micro-space bearings for cost optimization, paired with top global brand sourcing for specialized OEM requirements.
⚙️Product Application:
- Planetary Gear Units & Compact Gearboxes: Compact planetary gear assemblies, automotive transmissions, and industrial speed reducers.
- Hydraulic Pumps & Motors: Axial piston pumps, heavy-duty hydraulic motors, and fluid power equipment.
- Textile & Agriculture Machinery: High-density drive spindles, agricultural equipment gearboxes, and power take-off (PTO) shafts.
- Construction & Mining Equipment: Small-footprint reduction units, winch drive drums, and auxiliary drive assemblies.
⚙️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. |
