# Automation Bearings for Oscillating Joints and Low Stick-Slip Torque

Robot joints lose repeatability when seal drag and preload drift, not only when a catalog radial rating is exceeded. Thin-section bearings under moment load need careful mounting and clean assembly; a single particle reads as encoder noise for weeks.

Oscillating fretting differs from continuous rotation fatigue. Grease and seal friction belong in the axis error budget from day one.
