⚙️Product Description:
Are your clients’ rear hubs and freehub bodies wearing out prematurely under the immense torque of modern drivetrains? The 17287-2RS Bicycle Bearing (17x28x7mm) is specifically dimensioned for the 17mm internal axles found in premium 12mm thru-axle rear hubs. Because the rear wheel endures the brunt of pedaling forces, chain tension, and rider weight, this bearing is engineered with a high-capacity ball complement and full-contact rubber seals to resist water crossings and trail contamination. As an expert B2B bearing trader, we supply resilient RMO brand 17287 bearings in bulk, alongside comprehensive sourcing for specific OEM hub components, ensuring your wheelsets deliver relentless power transfer.
⚙️Product Features:
- 17mm Internal Axle Optimized: The 17mm bore is the exact industry standard for modern Boost and non-Boost rear hub shells and freehub bodies, ensuring a precise press-fit.
- High Torque Resistance: Engineered with premium SAE52100 chrome steel to withstand the severe radial loads and asymmetrical chain tension generated during aggressive sprints or steep climbs.
- Full-Contact 2RS Sealing: Equipped with heavy-duty dual rubber seals (often referred to as LLU or 2RS) that provide maximum protection against high-pressure washing and muddy cyclocross conditions.
- Nylon / Steel Retainer: Precision cages maintain ball separation under high-RPM descents, preventing cage failure and ensuring a long, quiet service life.
- B2B Global Supply: Leveraging our robust manufacturing network, RMO offers high-volume standard stock or customized grease/clearance options for international wheelset factories.
⚙️Product Application:
Built for endurance and power transmission, the 17287-2RS is the go-to component for:
- Premium rear wheel hubs (especially 12x142mm and 12x148mm Boost spacing).
- Multi-pawl and ratchet system freehub bodies (compatible with Shimano/SRAM cassettes).
- Heavy-duty Enduro and Downhill (DH) mountain bike wheelsets.
- Certain full-suspension mountain bike main pivot linkages.
- International hub manufacturers, custom wheel builders, and high-end cycling repair centers.
⚙️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. |
