Ball Bearing Adjuster, 2.5mm / 4-40, 4 Pack

Ball link with bearing for 2.5mm and 4-40 threaded rods or turnbuckles. Center screw fits 2.0mm hole.

4 per pack

The shaft of the link measures 5.37 in diameter and can be drilled to fit any sized rod 4/40 or 3mm is not a problem.

Note:
When using these the bearings must face the top. The 2mm screws head go up against the center ring of the bearing. There is a small plastic washer/spacer that sandwiches between the bearing and the servo arm. This is very important.

The 2mm screws are a perfect match to all of the Secraft servo arms that we sell
