Robotic Bearing Bore Size

Why Robotic Bearing Compactness Matters

Robotic bearing bore size directly impacts the performance, fit, and functionality of a robotic system.

Reducing the bore size of robotic bearings allows for a smaller outer diameter, helping minimize the overall envelope of robotic systems. This is especially valuable in compact or space-constrained applications.
