Product Overview

8 different offerings of our 25 Series Plate Sprockets. These are perfect for meshing with roller chain and finally getting that-thing-that-you-need-to-spin moving!

These aluminum sprockets work perfectly with any of our 6 hole hubs and mesh with #25 roller chain.  They also work with other build systems that use a 2 in. bolt circle for mounting. The larger versions also have a mounting pattern compatible with 2x1 box tube usefull for making arms.

Note: Despite the prints, at this time tooth alignment to holes is not controlled on these sprockets.

    Worked Great On an Arm

    These worked as a great drop-in replacement for VEXpro sprockets with the same 1.875" bolt circle for our 2023 robot arm. The larger diameters meant we were able to achieve a higher reduction, reducing motor current draw. They seemed machined to tight tolerances and held up the whole season without any bending or damage. Would highly recommend these to any FRC teams that need to build an arm or other pivoting mechanism. Arjun Bhatia FRC 7902: Markham FireBirds Mentor
