Competition-grade durability
Impact-resistant design: 30% thickening from the hexagonal hole to the edge of the track to avoid cracking under high loads (measured static load ≥ 1.8kN).
Zero Failure Record: 1000+ FRC team verified, adapting to frequent collision, start-stop and high-speed operation scenarios.
Accurately adapted to hexagonal shaft
Bore size 12.7mm (adapted to standard FRC hexagonal shaft), keyless installation, reducing the risk of transmission slippage.
Fast delivery guarantee
Regular delivery 7-10 days, direct shipment from China's three major ports (Guangzhou/Ningbo/Shanghai), support for urgent orders expedited.
1.FRC robot key transmission: robotic arm joints, drive hubs, lifting mechanism
2.Educational robot development: keyless connection solution for 3D printing/CNC machining parts
3.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. |
