Connecting aluminum profile with stainless steel

[everetthitch]

We are building a light detection system which works like a clock’s hand: an aluminum profile (the “hand”,shown in schematics) carrying detector assemply on its one end rotates around the other end; as the aluminum profile is quite long (2200L*40W*40H mm) and heavy (~10kg)，we will add a counter-weight to the other end of the hand to reduce the torque.The hand rotates around the center of the system through the inner part of a cross-roller bearing. The question is, is there any “off-the-shelf design" of a stainless steel “connection block” that connects the aluminum profile, the bearing and the counter-weight?

Unfortunately, there is no "off-the-shelf design" of a stainless steel connection block that will meet the requirements of your project. You will need to design and build a custom connection block to suit your specific needs. The best way to go about this would be to work with a qualified engineer who can help you design and manufacture the appropriate connection block.
