Linear Bearings

Linear Bearings

Linear bearings are designed to provide free motion in one direction and linear motion with minimal deflection and friction to the shaft. They can use a pad, bushing or a roller system to carry on a load that is not in a straight line. These bearings can reduce friction in motion systems where the motion functions in a straight or curved pathway. With heavier loads, linear guides with a re-circulating ball or roller bearings in the mounting pads or slide units are used to help bear the load. The rolling element of the bearing is what helps move a load. Basics are modified and added to these bearings to fulfill a range of manufacturing and industry needs. Linear bearings are used in both small and large applications. They are often used in pull-out equipment drawers, sliding doors, 3D printers, automation, and the medical industry. The following are some key considerations and benefits of linear bearings:

  • Reduced friction
  • Low noise
  • Simple structure
  • Easy lubrication
  • High performance
  • High load capacity
  • Long service life
  • Can deliver more precise motion control
