ONA Casting supplies GP300S main shaft assemblies forged from alloy steel. Each unit is 100 % dynamic-balanced and shipped complete with shaft, sleeves, key, seals and bolts. Fast global delivery, 1-year warranty, material and dimensional report included.
ONA Casting's GP (including GP-S) cone crushers are generally superior to original Metso in terms of one-time procurement costs, delivery cycles, spare parts prices. For users with tight budgets, short-term payback periods, ONA's imitation machines are "more cost-effective".
