⚙️Product Description:
Designing long drive shafts or lightweight frames where structural flexing is unavoidable, yet harsh dust threatens rolling elements? The 2206-2RS Sealed Self-Aligning Ball Bearing (30x62x20mm) is purpose-built to solve the twin challenges of shaft deflection and severe contamination. Featuring a 30mm bore, 62mm outer diameter, and a 20mm width, this double-row bearing incorporates a spherical outer raceway that automatically accommodates angular misalignment up to 2.5 degrees. Unlike open bearings, the 2206-2RS features dual-lip rubber seals that permanently lock out agricultural dirt, textile lint, and woodchips while retaining premium factory grease. It is the premier choice for combine harvesters, textile spinning frames, and industrial ventilation long shafts. As a flexible B2B bearing trading enterprise, we power your operational supply chain: boost your aftermarket profit margins with our field-proven RMO proprietary brand, or contract us to source premium international brands for high-precision OEM assembly lines.
⚙️Product Features:
- 2.5° Angular Misalignment Compensation: Dual-row balls roll smoothly within a concave spherical outer raceway, effortlessly absorbing mounting inaccuracies and dynamic shaft bending without increasing friction or temperature.
- Dual 2RS Rubber Dust Protection: Equipped with dual-side nitrile rubber seals (2RS) that provide superior sealing against abrasive environmental contaminants while drastically extending grease service life.
- High-Speed & Low-Friction Kinematics: As a ball bearing design, it generates substantially less operating torque and heat than spherical roller bearings, enabling higher rotational speeds and energy-efficient power transmission.
- Precision-Honed GCr15 Metallurgy: Forged from high-grade 52100 (GCr15) chrome steel with a rated dynamic load (~15.6 kN), ensuring long fatigue life and ultra-quiet operation under moderate radial stresses.
- Dynamic B2B Sourcing Versatility: We optimize your inventory logistics. Order bulk wholesale pallets of cost-effective RMO branded stock for agricultural parts distribution, or utilize our global network for OEM-certified international brand sourcing.
⚙️Product Application:
Perfect for application setups where long shafts flex and environmental cleanliness cannot be guaranteed, the 2206-2RS is vital for:
- Agricultural machinery: Combine harvesters, grain elevators, tractor drive shafts, and seed drills.
- Textile equipment: Spinning frames, roving machines, fabric guide rollers, and weaving looms.
- Woodworking machinery: Sawmill feed rollers, sanding equipment, and dust extraction drive shafts.
- Industrial HVAC systems: Ventilation blowers, centrifugal fans, and long line shaft supports.
⚙️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. |
