A bending machine for reinforcing rods and the like wherein a rod is placed between two mandrels which are mounted on axles in a mandrel carrier and the carrier and one mandrel is rotated about the axle carrying the other mandrel. Means for holding the fixed axle in firm bearing relationship with a semicircular bearing includes, in one embodiment, a semiannular key surrounding each axle which engages a semicircular key slot concentric with the bearing means for that axle when the axle is the one about which the apparatus rotates. Either axle can be the "fixed" axle about which the carrier rotates, permitting bending in either direction. In another embodiment the means for holding one axle in firm bearing relationship includes a T latch which is movable to either axle, the latch having complementary bearing surfaces.
