What are the procedures for replacing robot bearings?

11-07, 2023 / in News / by PRS

Robot bearings, also known as robotic bearings or bearings for robots, are specialized bearings designed for use in robotic applications. Robots require precise and smooth movement in various joints and components, and bearings play a crucial role in facilitating these movements. Replacing bearings in a robot is a task that requires precision and care to ensure the robot continues to operate smoothly and efficiently.

Robot bearings

  • Identify the Problem

Determine which bearing(s) need replacement. This might be due to unusual noises, increased friction, or visible wear and tear. Identifying the problematic bearings is crucial before proceeding with the replacement process.

  • Gather Necessary Tools and Bearings:

Collect the appropriate tools, including screwdrivers, pliers, bearing pullers, and lubricants. Also, make sure you have the correct replacement bearings that match the specifications of the old ones. Refer to the robot's manual or consult the manufacturer if you're unsure about the bearing specifications.

  • Turn Off the Robot and Disconnect Power:

Before you begin the replacement process, ensure the robot is powered off completely, and disconnect any power sources. Safety should be the top priority.

  • Disassemble the Robot:

Carefully disassemble the components around the bearing that needs replacement. This might involve removing covers, panels, or other parts that provide access to the bearing. Keep track of the disassembly process, and take pictures if needed to aid reassembly later.

  • Remove the Old Bearings:

Use appropriate tools to remove the old bearings. A bearing puller or press can help in gently extracting the bearing without damaging the surrounding components. Be cautious not to apply excessive force, which could cause damage to the robot parts.

  • Clean the Bearing Housing:

Once the old bearings are removed, clean the bearing housing thoroughly. Remove any debris, dirt, or old lubricant to ensure a clean surface for the new bearings.

  • Install the New Bearings:

Insert the new bearings into the housing carefully. Ensure they are properly aligned and seated securely. Use a press or a soft mallet to tap the bearings gently into place. Avoid applying force directly on the bearing's inner or outer race, as it can cause damage.

  • Reassemble the Robot:

Carefully reassemble the robot components in the reverse order of disassembly. Refer to the pictures or notes you took earlier to ensure everything is correctly put back together.

  • Lubricate the Bearings:

Apply an appropriate lubricant to the newly installed bearings. Consult the robot's manual or the bearing manufacturer's recommendations for the suitable lubricant type and quantity.

  • Test the Robot:

Power on the robot and conduct a series of tests to ensure it functions properly. Check for any unusual noises, vibrations, or issues with movement. If everything seems fine, the bearing replacement process is successful.

  • Regular Maintenance:

Implement a regular maintenance schedule for the robot, which includes checking and lubricating bearings as part of routine tasks. Proper maintenance can extend the lifespan of bearings and the overall robot system.

If you're not confident in performing the bearing replacement yourself, it's advisable to seek assistance from a qualified technician or the robot's manufacturer. Professional technicians have the expertise and specialized tools to ensure a safe and accurate bearing replacement process.
