It's a standard taper roller bearing. Measure the bore (Shaft diameter) of the inner part, the outside diameter of the outer race and the width of the outer race. You should then be able to identify it by looking here Bearing Units and Housings - SKF.
There is also the possibility that you will need a collapsible shim which gives the preload, you will have to get that from a main dealer.
The bearing will be cheaper from a bearing stockist but be sure to get a reputable make...SKF, FAG or Timken
