How to 3D Print Large Crossed Roller Bearings (with Metal Raceway)

Описание: Large metal crossed roller bearings are expensive. 3D printing can significantly reduce the cost, but fully 3D printed bearings don't last very long. In this video I design and make a large 3D printed crossed roller bearings (with a METAL RACEWAY) to create a hybrid design that is much cheaper than an all-metal commercial crossed roller bearing.
