  "id": "MLC-T-ADM-000207",
  "term": "Linear bearing",
  "field": "Additive manufacturing and 3D printing",
  "definition": "A mechanical component designed to provide free motion in a single direction along a linear axis or rod. In many desktop 3D printers, these components support the print bed or the print head assembly, guiding their movement along the X, Y, or Z axes with low friction. Common types found in printers include ball bushings, which contain recirculating ball bearings, and sleeve bearings made from self-lubricating polymers.",
