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.

Abstract: An industrial robot includes a robot arm having multiple connecting links connected by joints, wherein at least two adjacent connecting links are connected by a swivel joint and can be adjusted by a motor. A mechanical stop device defines a maximum rotatable adjustment angle between the adjacent links and includes a stop projection connected to one of the two adjacent connecting links, an engaging piece connected to the other one of the two adjacent connecting links, and a trailing stop which can be adjusted by the engaging piece. The trailing stop comprises a trailing stop body and an annular body which is connected with the trailing stop body and which is pivoted in an annular groove in an inner wall of a housing component of one of the two adjacent connecting links.

Abstract: The invention relates to an industrial robot which comprises a robot arm having multiple connecting links that are connected by means of joints, in which at least two adjacent connecting links, respectively, are connected by means of a joint, which is designed as a swivel joint, can be adjusted by means of a motor and is defined in its maximum rotatable adjustment angle by means of a mechanical stop device, which connecting links comprise a stop projection which is connected to one of the two adjacent connecting links, an engaging piece which is connected to the other one of the two adjacent connecting links and a drag stop which can be adjusted by the engaging piece, which drag stop comprises a drag stop body and an annular body which is connected with the drag stop body which is pivoted in an annular groove in an inner wall of a housing component of one of the two adjacent connecting links.
