OY2040 40Ton Heavy-Pneumatic Shop Press

The OY2040 40-ton heavy-pneumatic shop press is built for high-throughput industrial pressing operations where 40 tons of force must be delivered quickly and repeatedly throughout the production shift. Pneumatic actuation at 40 tons requires a large-bore, high-flow air circuit and a correspondingly robust frame structure to contain the reaction forces generated when the cylinder exhausts at full capacity. The OY2040's frame is fabricated from heavy-duty high-strength steel with integral welding specifically engineered for the shock loading characteristic of pneumatic cylinder cycling at this force level.
The heavy-pneumatic specification is the correct choice for production metalworking operations where the press is integrated into a line and must match the cycle time of upstream and downstream processes—manual hydraulic pumping at 40 tons is too slow for any but the most generous production cycle times, and the pneumatic circuit eliminates this constraint entirely. Force output is consistent across every cycle regardless of operator effort, improving batch quality by removing human variability from the pressing force equation.
The 1080 mm working range and 460 mm bed width are consistent with the OY2040S hydraulic press specifications, ensuring that the pneumatic and hydraulic variants of the 40-ton platform can serve the same component range. At 233 kg and packaged at 91 × 37 × 191 cm, the OY2040 is a permanent production-floor installation requiring a compressed air supply at 0.75–0.85 MPa. A clear pressure gauge allows real-time monitoring throughout the cycle.
