Yes, garage door roller sleeves or protective bearing caps are generally worth using if you want to extend the operational lifespan of your rollers and keep dust, dirt, and moisture out of the internal steel ball bearings. However, upgrading to premium sealed 13-ball-bearing nylon rollers provides a far superior, quieter, and longer-lasting solution than adding sleeves to old, worn-out steel rollers. Verification: Check that rollers spin freely without binding or grating resistance after installation.
