Description
Live idler XY joints for v2.4 and Trident. Machined from 6061 aluminium, with precision pins machined from stainless steel and press fit toothed idler.
Revision 1.1
- Now compatible with Carbon Fiber beam
- Countersunk M5 screws for better rigidity
Why Live Idlers
Unlike idlers with built-in bearings, live idlers use a freely rotating shaft supported by bigger bearings in the joint itself. This design offers several advantages:
- Improved Durability – Traditional bearing-integrated idlers rely on small, pressed-in bearings that wear out quickly under constant belt tension. Live idlers shift the load to larger, more robust bearings in the assembly, extending service life.
- Higher Load Capacity – By decoupling the pulley from the bearing, live idlers can handle higher belt tension and side-loads without deforming or binding.
- Smoother Motion – With reduced friction and more precise alignment, live idlers minimize belt drag and improve motion accuracy, which translates into cleaner prints.
- Easier Maintenance – When a bearing eventually wears, you replace only the standard bearing in the joint, not a specialized idler pulley. This makes servicing simpler and cheaper.
- Better Alignment – Live idlers ensure consistent tracking of belts since the rotating element runs concentric with the shaft, avoiding wobble or tilt that can occur with small pressed-in bearings.
