Product Overview
The ABB 3HAC10847-1 is a specialized service kit and mechanical spare part from ABB’s industrial robotics division, designed as a comprehensive solution for maintaining and repairing specific robot joints. This kit typically contains a complete bearing pack or seal replacement set for a major robot axis, such as axis 2 or 3 (the “shoulder” and “elbow” joints) on robots like the IRB 6600 or similar models. It serves the critical function of restoring the mechanical integrity and precision of the robot’s rotational movements by replacing worn or damaged bearings and seals that are subject to high loads and continuous operation. The ABB 3HAC10847-1 is supplied as a genuine, factory-matched kit, ensuring all components within—from the specific bearings and spacers to the sealing O-rings—are engineered to work together perfectly, guaranteeing optimal fit, performance, and longevity post-repair, which is essential for maintaining the robot’s payload capacity, path accuracy, and overall service life in demanding production environments.

Key Functions & Design Advantages
This service kit has been engineered to provide a complete, “all-in-one” solution for a major mechanical refurbishment of a robot joint. Its primary function is to return the robot’s kinematics to their original factory specification by eliminating backlash, vibration, and stiffness caused by worn bearings and compromised seals. The ABB 3HAC10847-1 offers a significant logistical and technical advantage over sourcing individual components separately. Every item in the kit is precisely matched—bearings are pre-selected to the correct tolerance groups, shims are sized to achieve the exact pre-load, and the provided grease is the specific type and quantity required for that joint. This eliminates guesswork and compatibility errors for the maintenance technician, dramatically increasing the success rate and durability of the repair.
The design and curation of this kit reflect ABB’s deep understanding of robotic service needs. Using the genuine 3HAC10847-1 kit ensures that the replacement components meet the original equipment manufacturer’s (OEM) standards for material quality, heat treatment, and sealing performance. This is critical for maintaining the robot’s dynamic performance and protecting the internal gears and motors from contamination. The included sealing components are vital for keeping the designated lubricant in and external contaminants like water or abrasive dust out, which is especially important in challenging environments like foundries or wash-down areas. By providing everything needed in a single package, ABB enables efficient planning and execution of preventative or corrective maintenance, minimizing robot downtime and ensuring the repaired joint operates with renewed smoothness, accuracy, and reliability.
Application Scenarios
The ABB 3HAC10847-1 is deployed during planned, major preventative maintenance or in response to diagnosed mechanical wear. A classic application is in automotive stamping plants, where IRB 6600 robots handle heavy sheet metal blanks. The constant high torque and inertial loads on axis 2 (the main “shoulder” joint) lead to eventual bearing wear, manifesting as increased vibration or audible noise. Replacing the joint components with this kit during a scheduled line shutdown restores smooth, precise motion, which is critical for accurately placing large metal sheets into presses without collision.
