Plain Linear Bearings - Closed

What is the difference between a closed and open linear bearing?

The closed variants of Simplicity plain linear bearings are ideal for handling loads in all directions and offer a number of mounting options. This is as opposed to open variants which allow the shaft to be attached to a rail for greater system rigidity. Both types are offered in Inch, ISO Metric and JIS sizing options
