So What Exactly is a Linear Motion Bearing?

How cool — the folks at Design World just posted a cool new video all about linear bearings! We sponsored this four-minute segment that gives you a basic understanding of linear motion systems.

The gist of it:
  • A bearing normally uses a bushing, pad or roller to move something along a rail that doesn't necessarily have to be a straight line
  • The rail can be pretty much any length, depending on the actuator
  • How long the bearing lasts depends on the load's weight and the speed it's carried
  • Tracks come in different profiles: Flat, round rods or something more complex with polished ground surface
There's more, but it's best explained in the video itself ... enjoy!
