What is a crossed roller slide? - Linear Motion Tips

24/9/2015· What is a crossed roller slide? As their name suggests, crossed roller slides (also referred to as crossed roller bearings) are linear bearings that use cylindrical rollers—as opposed to balls—to carry a load. The rollers ride between parallel guides in which v-shaped grooves have been ground. The term “crossed” refers to the fact that
