⚙️Product Description:
The 16287-2RS (also designated as 61902/16-2RS) is a highly specialized 16x28x7mm extra-light thin-section ball bearing. While standard 6902/61902 bearings feature a 15mm inner diameter, this unique variant is engineered with an expanded 16mm bore while maintaining a compact 28mm outer envelope. Designed specifically to accommodate 16mm oversized shafts and alloy bicycle axles, it eliminates the need to enlarge outer hub housings or re-engineer mounting spaces. Manufactured with dual contact rubber seals and pre-packed with waterproof synthetic grease, we supply these sought-after replacement and OEM bearings under our RMO brand, alongside comprehensive multi-brand sourcing for global cycle and precision engineering buyers.

⚙️Product Features:
- 16mm Expanded Bore Integration: Directly accommodates 16mm thru-axles within a narrow 28mm outer shell, increasing shaft rigidity without adding unnecessary frame bulk.
- Dual-Lip Rubber Seals (2RS): Dual contact rubber seals form an impenetrable barrier against mud, trail grit, and water spray during intense outdoor use.
- Pre-Lubricated Waterproof Grease: Factory-filled with premium high-viscosity synthetic grease, protecting raceways against micro-pitting and corrosion under wet conditions.
- Optimized Lateral Clearance: Precision GCr15 steel raceways are ground with specific radial clearance to absorb side-loading forces during aggressive cornering.
⚙️Product Application:
Tailored for 16mm axle integration and high durability in harsh environments, the 16287-2RS / 61902/16-2RS is widely used in:
- High-performance cycling: front and rear wheel hubs, freehub bodies, disc brake axles, and suspension pivots.
- Compact brushless motors: high-torque drone drives, RC model power units, and gimbal stabilizers.
- Robotics & automation: miniature rotary encoders, joint actuators, and lightweight robotic arms.
- Medical handpieces: dental equipment drivers, portable diagnostic readers, and laboratory agitators.
⚙️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. |
