⚙️Product Description:
The 16004 series (20x42x8mm) is an ultra-narrow deep groove ball bearing belonging to the extra-light ISO 16000 dimension series. Designed specifically to resolve tight axial length restrictions, it features a 20mm inner bore and 42mm outer diameter matching the popular 6004 radial footprint, but reduces total width to just 8mm—saving 33% axial envelope space compared to standard series bearings. Available in low-friction metal shields (16004ZZ) or dust-tight rubber seals (16004-2RS), we supply these high-speed, space-saving components under our trusted RMO brand, backed by global multi-brand OEM procurement for electrical motor and automotive equipment builders.
⚙️Product Features:
- 33% Axial Space Reduction: Maintains standard 20x42mm radial mounting dimensions while trimming width to 8mm, freeing up vital internal axial space for compact designs.
- Reduced Rotational Mass: The lighter ring geometry lowers total assembly mass and rotational inertia, driving up motor acceleration response and overall system energy savings.
- High-Speed Operational Stability: Precision-honed raceways and tight tolerances handle continuous high RPMs with minimal friction, heat buildup, or acoustic noise.
- Dual Protection Options: Select ZZ steel shields for low-torque high-speed oil lubrication, or 2RS contact rubber seals to isolate dirt and moisture in demanding work environments.
⚙️Product Application:
Optimized for compact axial envelopes and swift rotational speed, the 16004 bearing is widely specified in:
- Automotive accessories: car alternators, starter motors, tensioner pulleys, and auxiliary pump drives.
- Compact power tools: cordless hand drills, angle grinders, high-speed rotators, and planar equipment.
- Industrial electronics: optical rotary encoders, textile high-speed spindling units, and stepper actuators.
- Light e-mobility: electric skateboard wheel hubs, scooter gearboxes, and lightweight drone gimbals.
⚙️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. |
