Hello everyone, I have been tasked with finding an off-the-shelf Bearing Isolator specifically designed for sleeve bearings. We previously had a sleeve bearing with a traditional isolator that failed due to metal-to-metal contact with the housing. I have been researching off-the-shelf bearing isolators, but all I have found are designed for ball bearings which are not suitable for the axial and radial movements present in sleeve bearings. Has anyone come across off-the-shelf isolators designed specifically for sleeve bearings? Any advice or recommendations would be greatly appreciated. Thank you, Habib.

Our motors with sleeve bearings are equipped with INPRO style bearing isolators, ensuring optimal performance and protection against contaminants.
I'm glad to hear your positive feedback, electricpete! Can you share details on the axial and radial movements, as well as the shaft speed you're experiencing? Are you satisfied with these parameters and how frequently do you find yourself replacing the bearing isolator? I'm currently exploring options from both Inpro and Protech for my own project.
Hey Habib, I faced a similar situation last year and I found a solution with the Guardian Bearing Isolators from Inpro/Seal. They're designed specifically to support sleeve bearings and perform well with axial and radial movement. The best part is their non-contact design, which completely eliminates any metal-to-metal contact situation like you described. However, every case can be unique, so it's important to communicate your specific needs to the vendor to ensure the isolator will be a good fit. Hope this helps!
Hey Habib, your challenge resonates with a similar issue I faced a while ago. What you might be looking for is a labyrinth seal type bearing isolator. They can handle oscillations and movements that sleeve bearings typically present. Garlock's KLOZURE® Model 26 might be an option for you, as it's been designed for sleeve bearing applications. If you're dealing with high axial displacements, look for a bearing isolator that has an axial labyrinth as well. However, you need to ensure your chosen isolator is compatible with your specific application. Hope this helps!
Hey Habib, I totally understand the challenge you're facing! Have you checked with manufacturers like Garlock or KMS? They often have specialized solutions for sleeve bearings and might offer off-the-shelf options that fit your needs. Additionally, considering the specific axial and radial movement requirements, it's worth looking into custom solutions from smaller manufacturers, as they might provide tailored designs without a long lead time. Good luck, and I hope you find what you need!
