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.
