Specification Brand : Generic BulletPoint : BF 12.7mm*12.7mm Plum coupling elastic coupling servo motor coupler OD30 L42 BulletPoint1 : Package Includes: 1pcs 14mm - 19mm Connector Flexible Coupler,1 pcs hex wrench. Size: 66 x 40 mm/2.6 x 1.6 inch (H*OD Dia.) BulletPoint2 : Material - The plum flexible shaft coupling is primarily made of aluminum, a lightweight durable corrosion resistance, and heat dissipation metal. BulletPoint3 : Plum Design - The coupling features a plum-shaped design, which provides flexibility and damping properties to absorb shocks, vibrations, and misalignments in the connected shafts. The coupling can be disassembled and used on its own. BulletPoint4 : Function - The flexibility of the coupling shaft removes stress between the motor and drive components, allowing the coupling to compensate for slight angular and axial misalignment between the shafts, reducing wear on the connected components. BulletPoint5 : Application - Flexible Couplings are suitable to offset axial, radial and dampen vibrations and torque shocks for 3D printers, CNC machines, servo motors, stepper motors, and other machinery.
