Product Overview

The ABB 3HAC16843-1 Robotics RMO 150 Lubricating Oil is a dedicated industrial robot lubricant associated with ABB robotic mechanical systems. It is used where the specified RMO 150 lubricant is required for compatible robot gearboxes and mechanical transmission assemblies.

Robot gearboxes operate through repeated acceleration, deceleration, reversing, and positioning cycles. These movements create changing loads across gears, bearings, and other internal mechanical surfaces. The correct lubricant helps maintain an appropriate oil film while limiting friction and mechanical wear during continuous operation.

For ABB robot maintenance, lubricant selection should always follow the specification for the particular robot model, axis, and gearbox. RMO 150 should not be treated as a universal replacement for other robot gearbox oils.

Technical Specifications

Product Features

• RMO 150 formulation for compatible ABB robotic mechanical applications.
• Suitable for specified robot gearbox lubrication and maintenance procedures.
• Supports lubrication of gears and other loaded mechanical surfaces.
• Helps reduce direct metal-to-metal contact within moving transmission components.
• Supports consistent lubrication during repetitive robot axis movement.
• Suitable for planned maintenance of compatible ABB robotic equipment.
• Helps manage friction and heat generated by loaded mechanical transmission components.
• Intended for applications where the specified lubricant grade is required.

Working Principle

Inside a robot gearbox, lubricant separates contacting mechanical surfaces with an oil film. As gears rotate and transfer torque, the oil reaches the gear teeth and bearing surfaces, reducing direct contact between metal components.

Robot axes frequently change speed and direction. These operating cycles create variable contact loads and sliding conditions inside the transmission. Maintaining the specified lubricant level and lubricant grade helps keep the oil film available across these changing conditions.

During maintenance, the lubricant is normally replaced or replenished according to the robot manufacturer’s service procedure. Correct oil quantity is important because insufficient lubrication can increase friction and wear, while excessive lubricant can also create undesirable operating conditions.

Role in a Robotics Gearbox Control Architecture

The ABB 3HAC16843-1 is a mechanical maintenance component rather than an electrical control device. Its function supports the gearbox within the robot’s axis transmission system.

A typical robot motion chain can be represented as:

Robot Controller → Robot Drive → Servo Motor → Gearbox → Robot Axis → Mechanical Load

The controller determines the required robot movement, while the drive and motor generate the rotational motion. The gearbox transfers and modifies the motor’s torque and speed for the robot axis. The lubricant works inside this mechanical transmission to maintain suitable lubrication conditions for gears and bearings.

Proper lubrication therefore supports the mechanical condition of the axis transmission and helps maintain consistent operation over repeated robot cycles.

Industrial Applications

• ABB industrial robot maintenance for compatible mechanical assemblies.
• Robotic assembly lines with repetitive axis movements.
• Automotive manufacturing robots.
• Material handling and machine tending systems.
• Robotic welding cells with high-cycle axis operation.
• Palletizing and packaging robots.
• Industrial robot gearbox servicing.
• Preventive maintenance programs for compatible ABB robot systems.

Installation and Maintenance

1. Confirm the robot model and axis before applying the lubricant. The lubrication requirement can vary between different robot mechanical assemblies.
2. Verify the specified lubricant grade against the applicable ABB maintenance documentation before servicing the gearbox.
3. Clean the lubrication area around the filling or service point before opening the system to prevent contamination.
4. Use clean filling equipment that is suitable for the lubricant and has not been contaminated by incompatible oils.
5. Avoid uncontrolled lubricant mixing with other gearbox oils unless compatibility has been confirmed.
6. Follow the specified oil quantity for the particular gearbox or axis. Do not determine the filling quantity only by visual inspection.
7. Inspect gearbox seals and service points for oil leakage during routine maintenance.
8. Check gearbox temperature during normal robot operation. An abnormal temperature increase should be investigated rather than corrected only by adding lubricant.
9. Monitor mechanical noise during robot movement. New or increasing gearbox noise can indicate lubrication or mechanical problems.
10. Keep unused lubricant properly sealed to reduce exposure to dust, moisture, and other contaminants.
11. Record each lubrication service with the robot identification, axis, lubricant grade, service date, and maintenance activity.
12. Dispose of used lubricant properly according to the facility’s industrial waste-handling and environmental procedures.

Technical FAQs

Is ABB 3HAC16843-1 suitable for all ABB robot gearboxes?

No. Different ABB robot models and gearbox assemblies can have different lubricant requirements. The specified lubricant for the particular robot and axis should be verified before use.

What should be checked before adding RMO 150 to a robot gearbox?

Check the robot model, axis or gearbox identification, specified lubricant grade, required oil quantity, and applicable maintenance procedure. The condition of the existing lubricant should also be considered.

Can RMO 150 be mixed with another robot gearbox lubricant?

It should not be mixed with another lubricant unless compatibility has been confirmed. If the existing oil is unknown or differs from the specified lubricant, the applicable maintenance procedure should be followed.

What symptoms may indicate a robot gearbox lubrication issue?

Abnormal gearbox noise, increased temperature, visible oil leakage, unusual mechanical resistance, or changes in axis movement can indicate a lubrication or mechanical issue. These symptoms should be evaluated together with the gearbox’s mechanical condition.
