6400 / 16000 / 88500 Series Deep Groove Ball Bearings – Heavy Duty, Thin Section and Insert Type

Series Overview

This page covers three specialist deep groove ball bearing series that complement the standard 6000, 6200 and 6300 ranges.

The 6400 series is the heavy-duty deep groove ball bearing series with the largest outer diameter and highest load ratings of any standard single-row DGBB, 14 models from d 17 to d 80 mm.

The 16000 series (thin section) uses a dramatically reduced B-dimension for applications where axial space is the primary constraint, 9 models from d 17 to d 55 mm.

The 88500 series (insert type) features an extended inner ring for direct shaft mounting without a machined housing, commonly used in agricultural equipment and conveyor shaft assemblies, 7 models from d 35 to d 60 mm.
