Non-standard Bearing
FR8ZZ hexagonal bearings designed for FRC robots, made of high-carbon chrome steel, ABEC-3 precision, ZZ double dust seals, fast delivery in 7-10 days. Direct delivery from stock, support OEM customization! Improve the load capacity of robot joints, 0 fault verification.
Specification
The FR8ZZ hex bearing, specially designed for the FIRST Robotics Competition (FRC), has gone through several rounds of technological improvements, and has become a reliable core component for robotics teams around the world, with its core advantages of thicker inner rings, enhanced load capacity, and low-noise operation. The FR8ZZ Hexagonal Bearing is the core component trusted by robotics teams around the world.
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.

Q: Can FR8ZZ bearings replace ordinary deep groove ball bearings?
Yes, but we need to confirm the shaft type. The hexagonal hole design is optimized for hexagonal shafts. If you use round shafts, we suggest you choose standard bearings (e.g. 608ZZ).
Q: Does it support high precision customization above ABEC-5?
We can provide ABEC-5/7 precision program (delivery time extended by 3-5 days), please contact customer service for quotation.
Q: How to install hexagonal bearings to avoid damage?
Use the special hexagonal shaft adapter, and prohibit hammering installation. Free PDF installation guide is available.
