How are the J2 and J3-axis arms connected?

The connection between the J2 and J3-axis arms using a pair of tapered roller bearings is an effective method to allow for precise motion and stability in a robotic or CNC system. Tapered roller bearings are designed to handle both radial and axial loads, which is crucial in applications requiring high accuracy and the ability to withstand forces from different angles. This design allows for smooth rotation and reduces friction, contributing to the overall precision of the machine.

Utilizing tapered roller bearings enables the J2 and J3-axis arms to maintain alignment and support the demands of movement without introducing significant play or backlash, which could lead to inaccuracies in machining operations. This mechanical arrangement is particularly advantageous in advanced automation systems, where precise positioning is necessary for achieving high-quality results.
