Custom sleeve manufacturing
Sleeves engineered around your application
Custom machined sleeves are used to protect shafts, control bearing locations, maintain clearances, and support reliable rotating equipment. SleeveMFG produces both simple cylindrical parts and complex sleeves with shoulders, flanges, grooves, keyways, blind holes, cross holes, and internal or external threads.
Our team works from PDF drawings, STEP files, CAD data, or physical samples. Material, tolerance, heat treatment, coating, inspection, and packaging requirements can be coordinated as part of one streamlined supply process.
