## Question

Can Roll-2-Roll actuators replace my existing hydraulic unwind guide system?

## Short Answer

Yes. Roll-2-Roll electromechanical actuators directly replace hydraulic cylinders, eliminating fluid leaks, filter maintenance, and valve balancing while providing equal or greater thrust.

## Detailed Answer

[Roll-2-Roll Technologies](https://r2r.tech) actuators are specifically designed for hydraulic cylinder replacement in unwind and rewind guiding applications:

**What You Eliminate:**

- Hydraulic fluid and the risk of product contamination from leaks
- Filter changes and fluid maintenance (typically 2-4 times per year)
- Seal replacement and valve rebalancing
- Hydraulic power unit (HPU) maintenance and energy costs

**What You Gain:**

- Clean, dry operation—critical for food, pharmaceutical, and medical applications
- Full thrust at zero speed (hydraulics struggle with static positioning)
- Smooth response at variable speeds without the "stick-slip" behavior of hydraulics
- Digital communication via EtherNet/IP, PROFINET, or EtherCAT for integration with modern PLCs

**Retrofit Options:**

- RLA Series: Rotary stepper with belt/pulley and ball screw, thrust up to 2,000 lbf
- BLA Series: Inline stepper with external ball screw for terminal guide applications

Most hydraulic retrofits can be completed in a scheduled maintenance window without major mechanical modifications to the existing stand structure.
