What are the main applications of a screw jack?

•Height adjustment of clamps when securing machined workpieces. •Used in combination with clamps to ensure stable and precise positioning. •Supports heavy loads in fixture assemblies for machining operations. •Provides fine-tuned leveling for components requiring precision.

How does the SJK-K model differ from other screw jacks?

The SJK-K model features a through-hole in the center, allowing it to be fixed in place using bolts for added stability. This design is especially useful in high-precision clamping setups where movement needs to be restricted.

What makes the SJK screw jack ideal for machining applications?

•Precision height adjustment allows fine-tuning of workpieces. •High-strength steel construction ensures durability under high loads. •Compatible with various clamps for versatile workholding solutions. •Threaded adjustment mechanism enables smooth and controlled positioning.

How does the screw mechanism ensure smooth height adjustments?

The precision-machined threaded screw mechanism allows for incremental height adjustments, ensuring precise leveling and consistent clamping pressure without shifting.
