Why Upgrade to RMO FR8ZZ?
• Thicker Inner Ring: Reinforced design prevents cracking under shock loads (a common issue with generic bearings).
• Perfect Hex Fit: Precision-ground 1/2" Hex Bore ensures a zero-slip fit with leading North American robotics brands.
• Premium Material: Made of GCr15 Chrome Steel (not soft Carbon Steel) for superior hardness and durability.
• OEM Ready: We offer custom laser marking on the shield – put your team or company logo directly on the bearing!
• FRC robot key transmission: robotic arm joints, drive hubs, lifting mechanism
• Educational robot development: keyless connection solution for 3D printing/CNC machining parts
• Industrial lightweight equipment: automated production lines, precision rotating parts for testing instruments.
| 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. |
