Semiconductor Equipment Bearings Where Cleanliness and Runout Dominate
Wafer handling, vacuum robots, and precision stages care more about particle generation and runout than about raw load capacity. Thin-section and angular-contact bearings appear where envelopes are tight and motion must stay smooth under cleanroom rules.
Lubricant choice is constrained by outgassing and cleanliness classes. A grease that works on a factory conveyor can contaminate a vacuum chamber. Document fill quantity, cage material, and preload with the bearing designation so a later swap does not reopen process qualification.
