Abstract
An industrial robot includes a robot control configured to execute a robot program and a robot arm having a plurality of links connected by joints. The joints are configured to automatically adjust the links relative to one another according to the robot program, wherein at least one of the joints is configured as a rotary joint that connects a first link of the plurality of links to an adjacent second link for rotation relative to one another. The first link comprises a shaft sealing ring that has a sealing lip formed from a PTFE material, and the second link has a shaft portion with a running surface formed from a PTFE material, on which the shaft sealing ring bears with its sealing lip in a sealing manner. A method for moving the robot arm in a clean room is also disclosed.
