Linear Plain Bearings

Linear plain bearings are bearing elements for translation type motion (motion along a path). Unlike roller bearings, linear plain bearings move on a shaft or static guideway, as opposed to on movable component slides. Depending on the type of guiding system, the sliding layer is applied to the rigid or movable component.

Types of linear plain bearings

Linear plain bearings are available in a wide range of sizes and material types, suited to different applications. They come in three main configurations: closed, open and split.

What are linear plain bearings used for?


Linear plain bearings are resistant to shock and contamination. They offer high static load capacity and low wear, and make little noise. These characteristics make them suitable for applications where the bearing position must be low maintenance or maintenance free, or where lubrication is either impermissible or undesirable. They are found in in everyday applications including:

  • Printers
  • Lab equipment
  • Thermoperformance
  • Additive manufacturing
  • Welding machines
  • Stone saws and heavy-duty cutters
  • Assembly and inspection stations
  • Seat adjustment and shock absorption
