Flange Shaft Coupling Weight Reduction Flange Coupling Connector For Intelligent Robot Equipment For Engineering Feature:1. The flange shaft coupling is designed to reduce weight to reduce unnecessary rotational mass.2. The flange coupling is balanced in weight and volume, so it can effectively avoid the centrifugal force and vibration caused by the unbalanced weight and volume of the parts in high-speed applications.3. The flange coupling joint avoids centrifugal force and vibration and is ideal for high-speed applications.4. There are 6 M4 threaded holes with 8mm pitch in a 16mm grid. These M4 threaded holes provide excellent installation flexibility for these lightweight hub axle mounts.5. Can connect the shaft to other parts, suitable for intelligent robots, engineering and equipment, etc. Specification:Item Type: Flange CouplingMaterial: Aluminum Alloy Model: 3308-0016-1006Middle Bore Size: 6mm hole D.Application: Can connect the shaft to other parts, suitable for intelligent robots, engineering and hardware, etc. Package List: 2 x Flange Couplings Note: Please match the right size of your project before installation and use 1) we accept Alipay, West Union, TT.
