LM76 has manufactured stainless steel and self-aligning linear ball bearings. These bearings feature a lubrication fitting, along with an alignment set screw in both the pillow and flange blocks. The linear ball bearings have undergone modifications by utilizing an alignment that is flat ground on the outer shell of the bearing as well as driving in a hole through the outside shell. Lubricants may be pumped directly into a linear ball bearing without requiring the removal of the bearing from the shaft.
