OEM/ODM Available Spring Balancer with Stainless Steel Wire Rope for Construction

Honestly, the biggest thing people don't realize is working stroke—1.5m is standdard, and while our company can customize it, that's the baseline, so if you need a longer reach for high ceiling, just let us know the exact length you need, it's pretty straightforward to adjust.

But for most assembly lines and automotive work, that 1.5m stroke actually covers the vast majority of tasks, and what really makes it work is the ±0.1kg accuracy—it's tighter than most mechancial balancers out there, so operators don't feel that annoying tug or sag when they're moving a 20kg tool around.

We've got models from EW-3.0 up to EW-120, covering 1.0-120kg load capacity, and the stainlss steel wire rope comes in 3.0mm, 4.2mm, or 5.1mm diameters—most buyers go with the 4.2mm for general use, it's a good balance of strength and flexibility, and the anti-rust coating on the carbon steel body holds up well in humid workshops (just don't leave it submerged in water, obviously).

MOQ is just 1 unit, so you can test one before committing to a bulk order, and bulk pricing kicks in around 20 units or so—roughly 15-20% off depending on the model and color customization (standard yellow is fastest, custom colors add about 10 days to lead time).

What this isn't suited for is any application that needs a powered or pneumatic balancer—it's purely mechanical hand operation, so if you're dealing with automated pick-and-place systems, you'd want something else, but for manual tool suspension, it's better than reagent grade alternatives we've seen.

Also, we usually have stock on the EW-3.0 through EW-60 models, but lead time for EW-120 or custom strokes is about 20 days or so—confirm before ordering if you're in a hurry, and we'll include the COA and TDS with every unit, no extra charge.
