The linear ball bearing linear bearings consists of hardened steel to guides within the complete system. Since the slide rail kits come with just one slider carriage, we have decided to offer extra carriages, or sliders, on our website for your consumption. These are identical to the units on the Heavy Duty Linear Slide Rail, and can be used with the existing rail and carriage. The carriages have a force adjustment device to enable you to make the carriages slide as easy or stiff as your application dictates
