EPL-U & EPR-U Gearboxes for Linear Actuators
The GAM hollow output EPL and EPR have been redesigned for easier installation with more integrated adapter plates and clamping collars.
The new EPL-U inline and EPR-U right angle hollow output gearboxes specifically address the difficulty of connecting a gearbox to a linear actuator. The hollow output and zero-backlash clamping collar create the quickest and most economical way to add a gearbox to a linear belt or ball screw actuator module.
The EPL series gearbox is the best value servo gearbox on the market with tens of thousands sold since 1998 with the best quality available for the price point.
The EPR series gearbox provides all the advantages of the EPL in a right angle configuration.
EPL-U & EPR-U Features
- A quick, simple, low cost solution used to mount onto off-the-shelf linear belt or ball screw module.
- Inline or right angle configuarations
- Ready to mount to your module with a customized output
- Hollow output with zero backlash clamping collar and integral mounting plate for shaft-input actuators - no additional coupling needed
