OY2020B-D 20Ton premium Hydraulic Shop Press

The OY2020B-D is a 20-ton capacity manual hydraulic shop press engineered for professional workshops demanding consistent performance and durability.This premium model features a reinforced H‑frame structure that minimizes frame deflection under full load, ensuring repeatable pressing accuracy across thousands of cycles. The extended working range of 0–955 mm accommodates large components such as truck axle housings, industrial gearboxes, and heavy equipment parts, while the 550 mm bed width provides ample lateral clearance for oversized workpieces or multiple fixtures. 
The manual hydraulic pump incorporates an integrated overload protection valve, calibrated to the 20‑ton nominal capacity, which prevents inadvertent over‑pressurization and preserves cylinder seal integrity. The frame is fabricated from high‑strength structural steel with full‑penetration welding at all load‑bearing joints, a construction method that distributes stress evenly across the structure and eliminates potential weak points. 
OY2020B is not a single feature but a suite of enhancements: tighter manufacturing tolerances on ram alignment, upgraded hydraulic seals rated for extended service intervals, and additional reinforcement at the base and crown of the H‑frame. These refinements translate into measurable improvements in alignment stability over the machine’s service life—a critical factor when pressing interference‑fit components where angular misalignment could damage bores or shafts.
