608 Slotted-Arm 90° Bellcrank
A 90° bellcrank that pivots on a press-fit 608 bearing (22.05 mm pocket on an 8 mm bolt or pin). It turns a push-pull rod or cable pull through a right angle for things like remote gate latches, hidden cabinet releases, RC linkages and attic hatch pulls. Each 50 mm arm has a fixed M3 clearance hole at the tip and a 3.4 mm adjustment slot from 20 to 40 mm, so you can change the throw and lever ratio without reprinting.
624 Bearing Servo Saver Bellcrank
A compliant steering bellcrank for RC trucks and robot linkages: the hub presses onto a 624 bearing (4 x 13 x 5 mm) and drives two 36 mm output arms through a pair of spiral leaf flexures, so curb strikes deflect the arms ~10° and spring back instead of stripping the servo. 83 x 83 x 7.5 mm, M3 clearance holes at both tie-rod arms and two link positions on the input arm, with the arm sides hitting the ring ends as built-in over-travel stops.
