Linear bearings are low-cost production linear motion systems for use with cylindrical shafts with infinite travel. Since the bearing ball is in point contact with the shaft, the operating load is small. The steel ball rotates with minimal frictional resistance, resulting in a smooth motion with high precision.

Linear bearings are widely used in electronic equipment, precision equipment such as tensile testing machines and digital three-dimensional coordinate measuring equipment, as well as multi-axis machine tools, punching machines, tool grinders, automatic gas cutting machines, printers, card sorting machines, food Sliding parts of industrial machinery such as packaging machines.

*Lubrication and friction

*Grease lubrication

The anti-corrosion oil is injected into the linear bearing. Anti-corrosion oil, air dry before adding grease.

It is recommended to use lithium soap grease with viscosity marked N0.2.

*Oil lubrication

If oil lubrication is used, it is not necessary to remove the anti-corrosion oil, According to the temperature change, the lubricating oil of ISO viscosity grade VG15-100 can be selected. The shaft lubrication can be supplied from the oil supply pipe or from the oil hole on the outer bearing seat. Oil lubrication is not suitable for non-porous sealed bearings because the seals will scrape the oil.
