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.
These versions do not have a slewing ring bearing (PRT) and are a low-cost alternative to our robolink® D joints. Replaceable coupling components can be used to adapt different shaft diameters on the output side.
