The steel common joint can be bent at any attitude (with a rotation attitude of 45 degrees), and the common joint can exchange the transmission direction at any angle. Originally, a motor shaft became facing south and related through a common joint, which may change the path of the rotating shaft to face the ground. It can isolate or soak up axial vibration and impact, has meaningful benefits such as excessive torque, small transmission inertia, huge adjustment angle, handy installation, wide application range, and long carrier life, and is appropriate for various general mechanical occasions.Universal joint description:5-6 represents a diameter of 5mm on one end and 6mm on the different end; (Use M4 machine screws for side holes)6-6 represents a diameter of 6mm on one finish and 6mm on the other end; (Use M4 machine screws for facet holes)Material: Exquisite iron electroplated5-6-6-6 5-5-4-5 4-4.4-6 3.17-5.3-6 3-5mm outer diameter 11mm, length 23mm, aspect fixing hole M43.17-3.3-4 3.17-4.2.3-3 3-3mm outer diameter 9mm, size 23mm, side fixing hole M34-8.3-3-8 6-8mm outer diameter 14mm, size 25mm, facet solving hole M45-8.8-8 6-8mm outer diameter 14mm, size 34mm, aspect fixing hole M4Each order has complete screws and 1-2 wrenches for every order.Scope of application: metallic universal joint is suitable for the use of motor directly shaft, and is appropriate for different metal adaptors akin to Model car, mannequin ship, robot, and so on
