A gear unit comprising a housing, two shafts arranged parallel with one another and each supporting a helically cut toothed gear, and two pairs of bearings supported by or relative to the housing in an arrangement in which each pair of bearings rotatably supports a shaft with the toothed gears of the two shafts being rotatable one relative to the other in mutual engagement, wherein two bearings of the two shafts lying to a common side of the inter-engaged helical gears are supported by a substantially common wall section of the gear unit housing, one of said two bearings being arranged to transmit to said housing wall section axial forces acting in a direction from the gears to the bearing and the other bearing being arranged to transmit to said wall section axial forces acting in a direction from said other bearing to the gears. The said two bearings of the two shafts lying to a common side of the inter-engaged helical gears may be taper roller bearings and the bearings of one shaft may be arranged in the manner of X type bearing configuration whilst the bearings of the other shaft may be arranged in an O type configuration.
