The Tamiya 70242 Universal Joint Set is aimed at model builders and club projects where flexible drive arrangements are useful. It helps illustrate mechanical transmission principles with straightforward parts and assembly.
This universal joint set supports power transfer at angles up to 45 degrees, allowing varied mechanical layouts. It contains three joint variants compatible with common shaft formats: 3mm hex shafts found in many gearboxes, 2mm hex shafts used in some underwater or compact gearboxes, and 4mm standard shafts used across the Tamiya Technicraft Series.
Produced from low-friction plastic for steady rotation, the joints are suited to moving models and teaching setups. The kit includes mounting brackets to broaden installation options and supplies two each of 2x33mm, 3x27mm and 3x50mm hex shafts together with 3mm screws and nuts for secure fixing.
