Endless Gear Rack and Pinion Modular Linear Actuator - drylin® EGW

Are you looking for a linear system for long travels?  Then discover our Endless Gear linear actuator with rack and pinion drive.  If rail profiles could be attached endlessly, it would even be possible to control several carriages in parallel or independently of each other. Users could also easily extend travels at a later point in time thanks to the rack and pinion segments - similar to a toy train.

The drylin EGW modular system provides you with everything from one source - from linear guide and carriages to chains and cables for energy supply. If required, we will deliver your kit ready to install, including motor and control system.

Detailed views of the linear module

Here you can see a single linear module in detail. Thanks to the modularity of the system, the modular system consists of pieces that are each only two meters long, which significantly simplifies handling and transport.

drylin w exchange bearings

drylin® W exchange bearings

Exchange bearings for 24/7 operation. Simple bearing exchange on the rail without disassembly. Liners can be easily replaced on the rail.
