Timing Pulley - Shaft Mount (15T; 0.25" Bore)

These shaft-mountable aluminum timing pulleys use XL timing belts and attach to a 0.25" output shaft with a set screw. They have 15 teeth with a gear pitch of 1/5P, an outer diameter of 1”, a bore of ¼", and requires a belt width of 3/8”.

Actobotics is a robotics building system based around extruded aluminum channels, gears, precision shafts, and ball bearings. Thanks to the two standardized hole patterns, nearly all Actobotics components can be intuitively connected together. The wide range of components makes building complex electromechanical prototypes or finished projects a reality.

  • Teeth - 15T at 1/5P
  • OD - 1”
  • Bore - 0.25"
  • Belt Width - 3/8”

Customer Comments

  • Do you think this bore size and pin screw will work with a 5mm shaft if I file it down flat a little on one side?
