⚙️Product Description:
The 6816 series (80x100x10mm) is a large-aperture extra-light thin-section deep groove ball bearing designed specifically for applications requiring large hollow shaft clearance and extreme weight control. Featuring an expansive 80mm inner bore combined with a narrow 100mm outer diameter and 10mm width profile, it allows electrical wiring, optical light paths, or hydraulic lines to pass through central shafts without expanding machinery dimensions. Available with double steel shields (6816ZZ) or contact rubber seals (6816-2RS) pre-filled with high-performance grease, we supply these space-saving thin-section bearings under our RMO brand while facilitating flexible multi-brand OEM procurement for global robotics, medical imaging, and automation manufacturers.
⚙️Product Features:
- Large 80mm Bore with 10mm Ultra-Thin Profile: Maximizes internal hollow passage space within a minimal 10mm cross-sectional envelope.
- Low Rotational Inertia & Resistance: Precision-ground GCr15 raceways and lightweight complement reduce starting torque and dynamic rotational mass.
- Compact Spatial Optimization: Replaces bulky standard-series bearings, saving substantial housing space and total equipment structural weight.
- Versatile Shielded & Sealed Options: Select 6816ZZ metal dust shields for high-speed low-friction operation or 6816-2RS rubber seals for superior dust protection.
⚙️Product Application:
Engineered for hollow-shaft integration, light structural weight, and compact spatial control, the 6816 bearing is widely specified in:
- Robotics & motion control: harmonic drive reducers, collaborative robot joints, and hollow rotary indexing tables.
- Semiconductor & cleanroom: wafer handling robotic arms, vacuum transport systems, and automated testing gimbals.
- Medical & optical equipment: CT scanner slip-ring mounts, dental diagnostic rotators, and optical tracking gimbals.
- Industrial automation: textile printing cylinders, packaging line turntables, and lightweight encoder 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. |
