Facom 30-ton Jack with Mechanical Screw (U.33A) - Used in conjunction with mechanical pullers, hydraulic jacks help separate the fittings to be removed. This U.33A is rated at 30 tons with 5mm of travel. During screw tightening, a shear-pin will protect the tools and user if the maximum allowable torque is exceeded (shear-pin rating is 110nm). When using both puller and jack, make sure generated forces are compatible. Never use with pneumatic tools!
The FACOM U.33A falls under the category of high-capacity puller boosters, mechanical-hydraulic force screws, or compact push-puller cylinders. It is designed to bridge the gap between pure mechanical pullers and fully isolated hydraulic pump setups by using a compact manual screw to generate immense axial separation pressure.
- Travel 5 mm.
- Shear-pin rating 110 Nm.
- Supplied with 2 shims/wedges (25mm & 50mm)(U33-13 and U33-11)
- 33mm diameter plunger
- Length : 260 mm, head height : 35 mm.
- Force : 30 tons ; 300 kN.
- 19 mm hexagonal screw.
- Shear Pin Set (3pc) (U.33GJ3)
The FACOM U.33A is a master-grade 30-tonne mechanical screw jack engineered for heavy-duty industrial dismantling operations. Typically deployed as a power-booster in conjunction with heavy mechanical pullers (like the FACOM U.102T set), this tool delivers an immense 300 kN of pushing force to release exceptionally stubborn bearings, gears, and pulleys without damaging machinery axles or shafts.
Key Specifications & Built-In Safety Features
- High-Power, Short-Stroke Piston: Driven manually using a standard 19 mm 6-point / hexagonal socket or wrench. It extends a thick 33 mm diameter plunger over a precise 5 mm travel distance to break frozen fits with maximum control.
- Calibrated Shear Pin Protection: To safeguard the user, workpieces, and parent puller arms from explosive failure under overload, the internal drive screw utilizes an integrated shear pin. This pin is structurally designed to shear cleanly at 110 Nm of input torque if maximum safe limits are breached.
- Included Extensions & Spares: Supplied from the factory with two extension shims / blocks (25 mm and 50 mm heights with a 40 mm diameter) to step out plunger reach, plus 3 spare shear pins (replacement part no. U.33GJ3).
- Critical Operational Warning: Never utilize impact guns or pneumatic air tools with the U.33A. Shock loads instantly trigger premature pin shearing and risk permanently destroying the internal mechanical screw threads
