Notes

Thrust bearing ratings are axial values Ca / Coa; T is the overall height. Weights are given in kg. Load ratings are shown in both the original catalogue units and the converted value (1 N = 0.2248 lbf). Data is provided for selection reference only - confirm against the latest official catalogue before ordering.
