Notes

Tapered roller bearings are cone / cup assemblies; cone and cup weights are listed separately and the total is their sum. 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.

Bearing life (ISO 281 basic rating life)

C / P	Equivalent load P (N)	L₁₀ (10⁶ rev)	L_10h at 500 rpm
4	35,500	102	3,386
6	23,667	392	13,083
