BSB MFG #7540-C XD Slider with Preload Bearing

The BSB MFG XD Slider features true duel bearing technology with a bearing at the base and a second bearing surface on the face of the plunger to give stability throughout its full range of motion. With a larger bore it can handle more side load than any other slider.
It is a Class III bearing that was design to replace a linear ball bearing setup. This bearing is designed to run in a dirty environment and carry 20 times the load of a linear ball bearing, and can do it with or with out lubrication.
