Description
Timing belt J4A for Mitsubishi RH-6FH SCARA robots
The timing belt RH-6FH J4A is available from ROBTEC as an original spare part, ex stock.
This original timing belt J4A for the Mitsubishi RH-6FH ensures reliable motion transmission to the fourth axis of your SCARA robot with 6 kg payload. The timing belt J4A is a critical wear part that significantly influences the rotational movement at the tool flange.
Role of the J4A timing belt
Timing belts transmit the rotary motion of the servo motors to the robot’s axes. The designation J4A identifies the specific belt in the area of the fourth axis. Wear manifests itself in declining repeatability, visible cracking or unusual running noise. A preventive change as part of routine maintenance avoids costly downtime.
