The Spring Cores
The xARM ships with a selection of three pairs of our polymer spring cores with an outer shell of neoprene. Neoprene is stronger and more resistant to heat, oil, solvents, water through vulcanization.
Each spring core has a smooth and linear lifting capacity. They perform their best when being used near their maximum weight capacity. Because of this, each spring core has a weight range of about 5 Kg / 11 Lbs, allowing the operator to fine-tune the arm to optimal performance.
The spring cores are easy to swap and adjust. Remove one screw and lift out the spring core to replace it with another, then screw back in. A short swap time to gain exceptional performance.
The xARM ships with the following spring cores:
- Blue 17-22.5 Kg / 37-49.5 Lbs
- Orange 20-25.5 Kg / 44.5-56 Lbs
- Purple 23.5-29 Kg / 52-64 Lbs
For lighter setups there are also a lighter spring core available:
- Teal 8-14 Kg / 17.5-31 Lbs
- Green 14-19.5 Kg / 31-43 Lbs
* For very heavy setups we can also offer custom made spring cores, up to around 35 Kg / 77 Lbs. Send us an email if you’d like to order a custom set of spring cores.
