Description of rotating frame parameters:
1. Continuous rotating mounting seat uses two precision bearings to realize smooth and clearance-free rotation. Aperture with M26 internal threads can install 25.4-inch optical elements with a maximum thickness of 11.9 mm.
2. The connecting rod element can be installed through M4 threaded hole.
3. The rotary dial has lace rolling to adjust the rotation. 360-degree laser engraved, 2-degree increment scale lines are used for precise, repeatable positioning and fine angle adjustment. Tighten the M4 fastening screw at the side to tighten the inner hexagon to fix the rotation of the dial.
