This is the 42 tooth pulley used in the AM14U family of chassis. It works with all 5 mm pitch HTD timing belts. This pulley has a 1.875 in. bolt circle making it easy to attach to many of our motion components. It also has a locking pattern that is compatible with many of our wheels.
This pulley comes as two identical halves that mesh with each other to create one pulley that is the correct width for a 15 mm timing belt.
Here is a 39 tooth HTD profile pulley, fitting any two 15 mm wide HTD timing belts. This is shipped as an un-assembled kit. The center bore accepts any flanged bearings with a 1.125 in. OD. It can also accept any of our legacy hubs listed here:
500EX Hex Hub am-2568
500EX Key Hub am-0976
625 Key Hub am-0214a
10 mm Key Hub am-0985a
10 mm DD Bore Hub am-2279

Belt Profile: 5 mm pitch HTD timing belt, 15 mm wide
If you need to increase the width of our 42 Tooth pulley, here is the solution! This pulley extension mates with existing pulley halves (am-2234). This pulley extension can be used in a variety of settings, such as a wider conveyor belt, multiple belt output, and much more by stacking multiple extenders back-to-back between our standard pulley halves.
