igus has developed a new type of linear actuator, drylin GRW-0630, which is fit for use in highly dynamic linear applications with low loads, particularly found in the pick & place sector. The motor is integrated into the carriage, rather than the end block, in this new linear drive system. As a result, the carriage and motor are static, allowing the rail to move vertically up and down quickly, up to one metre per second. Instead of power being transmitted via a traditional toothed belt drive, the actuator has been designed with a lightweight plastic rack that eliminates deflection and pretension, and allows for smooth strokes up to 150mm based on loads up to one kilogram. The profile material is aluminium, so combined with the plastic drive rack makes for a very lightweight complete system. It is a modular system complete with adaptor plates and connecting angle accessories that can be fitted with additional two or three linear gantries. The linear actuator is completely lubrication free, dirt and dust repellent, and provides a reliable service over a long life.
