6900 series dimension and load range

AttributeRange across published models
Bore diameter (d) 10 – 100 mm
Outside diameter (D) 22 – 140 mm
Width (B) 6 – 20 mm
Basic dynamic load rating (Cr) 3.35 – 56.2 kN
Basic static load rating (C0r) 1.25 – 41.9 kN

Each span is the minimum and maximum over the 21 published model pages listed below, whose values are model-bound catalog figures traceable to a collected source. The series page adds no numbers of its own; a designation not listed here is not yet published with evidence, and we confirm it at quotation on request.

Choosing inside the 6900 series

Within a designation series, the bore determines the shaft fit and the series digit trades section height against capacity: moving from the 6000 to the 6300 series at the same bore gives a larger outside diameter and width and, with them, higher load ratings. Use the range table to shortlist boundary dimensions, then confirm the exact model against your housing space, speed and load spectrum on its own page.

Executions (open, ZZ shielded, 2RS sealed) are published per designation where evidence exists; if your size appears only as an open execution and you need a sealed one, send both in the inquiry — we confirm availability at quotation.
