Introduction
When a screw jack fails on a production line, every hour of downtime costs money. Ordering a direct replacement from the original manufacturer often means waiting weeks — and paying a significant premium for it.
There is a faster, more cost-effective option.
LiuDrive manufactures precision screw jacks as 1:1 drop-in replacements for over 20 global OEM brands — same mounting dimensions, same load ratings, same gear performance. We work with buyers across different budget levels and application requirements, and can advise on the most suitable specification for your situation. Standard models ship in as little as 3 days.
This guide covers which brands we replace, how compatibility works, and how to get a quick confirmation before ordering — whether you are an engineer validating a specification, a procurement manager managing lead times, or a maintenance team looking to get a machine back online fast.

What Does “1:1 Screw Jack Replacement” Mean?
A 1:1 replacement means the alternative unit is dimensionally and functionally compatible with the original OEM product:
- Flange & mounting holes — bolts directly into your existing frame with no modification
- Screw diameter & lead — stroke speed and positioning accuracy unchanged
- Gear ratio — input torque and output force remain identical
- Load rating — rated capacity matches the original specification
- External appearance differs — finish and branding differ, but fit, form, and function do not
Every LiuDrive replacement is engineered against the original OEM drawing to ensure a seamless swap. Each model is matched to a specific OEM series — not produced as a generic off-the-shelf actuator.

Frequently Asked Questions
Will a LiuDrive replacement fit my machine without modification?
Yes, provided the model is correctly matched. Our replacements are dimensionally identical to the OEM original—same bolt pattern, same screw diameter, and same shaft dimensions. Absolutely no machining or frame modification is required.
Do you replace entire multi-jack systems, or just individual units?
Both. We supply individual jacks for immediate MRO (maintenance) replacements, and we also manufacture complete, synchronized multi-jack systems for OEMs and new equipment builds. We will perfectly match your original gear ratios and synchronization layout.
Can I order a single unit for testing before committing to a larger order?
Yes, our MOQ (Minimum Order Quantity) is 1 unit. Many engineers and distributors order a single sample first to validate fit and performance before placing bulk production orders.
I don’t have drawings or a full model number—can you still help?
Absolutely. A photo of the unit and its nameplate is usually enough. If the label is unreadable, our factory engineers will guide you on how to measure it quickly. Most of our 1:1 matches are successfully confirmed from photos alone.
My brand is not listed in this guide—can you still find a match?
Send us a photo or any details you have. We manufacture replacements for far more brands and models than listed here, and we can usually engineer a compatible alternative based on your basic dimensions and load specifications.
How fast can you deliver for an urgent MRO replacement?
Standard models ship directly from our factory within 3 working days. For extreme emergency maintenance situations, contact us immediately, and we will expedite the fastest available production option.
What warranty is included?
All LiuDrive screw jacks carry a 12-month factory warranty on key components, backed by lifetime technical support from our engineering team.
