679 models in the BT series, 711.2–3811 mm bore. Every row links to the full specification page and to the cross-reference page of that model.
BT series bearings follow the ISO dimension plan for this family, so a given number is dimensionally interchangeable between brands - see the cross-reference to confirm. Choose the suffix for your duty: shields for dry, clean positions, contact seals for wet or dusty ones, and a larger clearance class where the fit or temperature demands it.
