CYCK 51MM Ultra-long Stroke 12 Bearing 2-inch Dual Speed Toothed Focuser for SC Telescope C925HD/C11/C11HD/C14/C14HD

CYCK 51MM Ultra-long Stroke 12 Bearing 2-inch Dual Speed Toothed Focuser for SC Telescope C925HD/C11/C11HD/C14/C14HD

Advantages:
- Maximizing the focusing stroke in the shortest optical path: Thanks to the unique design of 3 rows and 4 sets of 12 point bearing support, the SCT focuser can achieve an ultra long focusing stroke even in a very short optical path. The stroke is optimized to 51mm, and the total length of the rack is 56mm, with a utilization rate of 91.07%. After the 40mm mark, it will automatically switch to 8-bearing support.
- Greatly enhanced stability: supported by 3 rows and 4 groups of 12 point bearings, and using enlarged bearings, the support force of the focusing cylinder is more uniform, with less deformation, greatly improving stability. It is also the most important secret to achieve ultra long focusing stroke with ultra short focusing bucket. After the 40mm scale, it will automatically switch to 8-bearing support.
- The probability of looseness is greatly reduced: among the 12 fixed points, if one point becomes loose due to various uncertain factors, it will not affect the overall support stability. Even if two or three points become loose, it basically has no effect. The probability of two or even three points in the same row becoming loose together is very small. After the 40mm mark, it will automatically switch to 8-bearing support.
