Questions about this item

What shaft and housing diameters does the 280x283x347mm thrust ball bearing fit?

The bearing suits a 280 mm shaft and a 283 mm housing bore, with an overall outside diameter of 347 mm.

Press the inner ring onto the shaft and the outer ring into the housing using a sleeve that contacts only the ring being seated; never transmit force through the rolling elements.
