robolink® joints are the moving connecting components between the individual connecting plates of the robot arm. igus® supplies them with worm gears and in different sizes. For the gear wheels and slewing ring bearings of the joints, high-performance polymers that contain dry lubricants are used. Additional lubrication is therefore not necessary. This makes robolink® maintenance-free and clean. In addition, use in dirty environments is possible without problems as dust particles cannot adhere to the joints. If robolink® D joints are combined with a stepper motor, the latter ensures movement with a high degree of repeating accuracy, even in the case of applications involving spray water. The joints are available singly and can be combined with special components.
