Constant cross-section bearings are a special category of thin section bearings. Unlike ordinary 618/619 thin wall bearings whose cross-section grows with the bore diameter, constant cross-section bearings maintain the same cross-section dimension no matter how large the inner diameter becomes.

This advantage makes constant cross-section bearings irreplaceable in large-diameter compact equipment. Designers can obtain a large hollow channel for wiring and pipeline layout without increasing equipment wall thickness.

Common application scenarios include hollow rotary platforms, large robot rotating supports, medical scanning equipment, surveillance turntables and semiconductor automation devices. Four-point contact constant cross-section thin section bearings are the most popular model due to comprehensive load capacity.
