KUKA KRC4 60GB00-183-962 Reduction Gear – RV320E-185 Series for KR30C4 Industrial Robots
When a reduction gear fails on a KUKA KR30C4 robot, the entire production line stops. Axis positioning errors, abnormal vibration, and torque loss cascade into unplanned downtime that costs manufacturers thousands of dollars per hour. The KUKA KRC4 reduction gear (Part No. 60GB00-183-962 / KPP600-20-140 / 00-198-260) is the precision mechanical heart of the robot’s joint drive system — without it, accurate, repeatable motion is impossible.
The RV320E-185 is a high-reduction-ratio RV (Rotary Vector) cycloidal gear unit engineered specifically for KUKA’s KR30C4 heavy-duty articulated robot arm within the KRC4 controller generation. As one of KUKA’s most widely deployed 30 kg payload robots in automotive body-in-white, foundry, and general handling applications, the KR30C4 demands a reduction gear that delivers zero-backlash precision and long service life under continuous industrial duty cycles. This part number is the OEM-specified replacement component, ensuring full mechanical compatibility and restoring factory-rated performance.
