Star points/arms are precision radial extensions on star wheels that engage with mating components to transfer motion in indexing and conveying systems.
Star points or arms are the protruding radial elements of a star wheel (also called Geneva wheel or Maltese cross mechanism) that precisely interface with slots or pins on a mating component. These components convert continuous rotary motion into intermittent or indexed motion through controlled engagement and disengagement cycles. They are critical for timing, positioning, and material handling in automated machinery where precise start-stop motion is required.

Star points typically refer to the tapered ends that engage with mating components, while star arms refer to the entire radial extension including the structural portion. In practice, the terms are often used interchangeably for the complete protruding element.
The number of arms depends on required indexing angle and duty cycle. More arms provide shorter dwell times and smoother motion but reduce torque capacity per arm. Common configurations: 4 arms (90° indexing), 6 arms (60°), 8 arms (45°).
Regular inspection for wear on engagement surfaces, lubrication of bearing surfaces (if applicable), and checking for proper alignment. Replacement is typically needed when wear exceeds 0.5mm or positioning accuracy degrades beyond specifications.
