INEC cross are constructed in forged material and thermally trated to guarantee it's strength the operations. The rolling trail's tolerance and the turning bodies are delimited in a way to warranty the best redemption during high rolations. The lubrification system by grease cups is disposed in 05 dots (to cross with torque above 19000 Nm), in other words: 01 central dot and 04 dots, as one to each cilindric bearing facilitating the lubrification process, so the cross has interior chanels to reach the spikes.
