Standard Reinforced 2.5T Transmission Pair
Φ30 thickened quenched trapezoidal screw paired with high-tin wear-resistant cast bronze worm gear. 6-grade precision milled gear teeth match 25% standard intermittent duty cycle, delivering far more stable self-locking performance under medium loads than small-tonnage models.
Multi-standard Flange Compatible Input Structure
Dual-side output shafts support IEC, NEMA and servo motor adapter flanges. Direct connection with all power sources without custom transition plates, plus reserved hand crank shaft for emergency adjustment to expand driving compatibility.
Wide Temperature Range Fully Sealed Assembly
Low & high temperature resistant composite grease inside, multi-lip imported oil seals on both housing ends, and telescopic bellows for screw rod. It operates stably from -20℃ to 100℃, suitable for both low-temperature workshops and high-temperature drying production lines.
Cost-effective for Medium-load Applications
Covers standard jacking demands of small & medium equipment. It has smaller outline and lower purchase cost than 5T models, and sufficient load margin compared with 1T jacks. It balances cost and safety redundancy for long-term intermittent medium-duty operation.
Freely Switchable Assembly Forms
Two screw output modes (A upward pushing, B downward pulling) and four mounting angles (vertical, horizontal, side-mounted, inverted). Three interchangeable screw end fittings (flange, clevis, thread) enable one unit to fit multiple tooling layouts.
Low-cost Standardized Synchronous Matching
Uniform shaft and flange dimensions fit off-the-shelf bevel gearboxes and drive shafts. Synchronous systems with 2/4/6 jacks require no custom non-standard connectors, shortening assembly cycle and reducing spare part replacement expense.
Q: What is the maximum allowable input speed of SWL 2.5T jack? What damage will overspeed cause?
A: The rated maximum input speed is 1500r/min. Long-term overspeed leads to severe heat and abrasion on worm gear teeth, which weakens self-locking function. It is recommended to limit operating speed within 1000r/min daily.
Q: How to choose between translating screw and rotating screw versions?
A: Type 1 translating screw is for stations requiring linear lifting without screw rotation; Type 2 rotating screw is for applications where the nut lifts loads while the screw spins in place. Type 2 is preferred for long-travel guided tooling.
Q:What is the operating temperature range of 2.5T jack? What modifications are needed for high-temperature environments?
A:Standard working temperature ranges from -20℃ to 100℃. For continuous temperature over 80℃, customized high-temperature grease and thickened heat-dissipating housing are optional to prevent grease failure and leakage.
