An eight-part bundle of genuine LEGO® Technic rotation joint and axle connector parts across four part numbers: two Technic Axle 1L with Pin 2L with Friction Ridges (11214), two Technic Brick Modified 1 x 2 x 1⅓ with Rotation Joint Socket (80431), two Technic Rotation Joint Ball Loop with 2 Perpendicular Pins with Friction (47455), and two Technic Rotation Joint Cylinder with Pin Hole and Rotation Joint Ball Half (1994).

Part Specifications — 11214, 80431, 47455 & 1994

The axle/pin connector (11214) combines a 1L axle and 2L friction pin in a single element, suited to compact pivot assemblies. The modified brick socket (80431) accepts a rotation joint ball directly into a standard 1x2 brick form factor, maintaining stud connectivity on the top face. The ball loop (47455) provides two perpendicular friction pins alongside the ball loop connection, enabling multi-axis articulation within a single part. The cylinder (1994) integrates a pin hole and ball half into one cylindrical housing, functioning as a self-contained joint anchor.
