Mini 0.5Ton Standard Trapezoidal Screw Structure
Equipped with compact self-locking T-screw and miniature tin bronze worm gear pair. Its friction angle exceeds thread lead angle, so light loads are firmly locked after power cut without sliding down.
Mini Integrated Lightweight Cast Iron Housing
One-piece cast compact iron body with tiny overall dimension. Standard single-side input flange supports two driving modes: hand crank and micro geared motor.
Simplified Dustproof & Sealing Assembly
Single oil-resistant skeleton seal embedded on housing end face, plus standard simple telescopic dust boot for screw rod. It blocks floating dust and mild water mist to protect internal transmission parts for normal indoor working environments.
Ultra-small Installation Footprint
The 0.5T mini body is much smaller than standard tonnage jacks, easy to embed into narrow machine frames, compact testing fixtures and desktop fine-adjustment equipment.
Labor-saving & Smooth Adjustment
Precisely polished worm and worm gear teeth reduce transmission resistance. Manual rotation works without jamming, and lifting height can be finely calibrated with stable positioning accuracy.
Low Operation & Maintenance Cost
Simple component layout without complex precision parts. Unified grease filling port simplifies regular maintenance, with low failure rate and easy operation for new operators.
Q: What is the rated load capacity of SWL 0.5T screw jack? Is short-time overload allowed?
A: Its standard rated load is 0.5 ton. Overload operation is forbidden. Short impact load shall not exceed 80% rated capacity, otherwise worm gear abrasion will accelerate and self-locking function may fail.
Q: Can multiple 0.5T jacks be linked for synchronous lifting?
A: Two units can form a synchronous lifting system matched with small bevel gearboxes and thin drive shafts for dual-station leveling. It is not recommended for synchronization of 4 or more jacks.
Q:What mini equipment scenarios are SWL 0.5T screw jacks applied to?
Desktop testing instrument fine-tuning tables, small lab lifting brackets, light packaging lifting stations, mini woodworking fixtures and tiny solar sample leveling devices.
