In the selection of lubricants, we need to choose based on practicality. Some lubricants have the effect of reducing friction and preventing its exchange, some lubricants have the effect of reducing surface stress between rolling surfaces and extending their service life, and some lubricants can prevent surface rust and fully improve their utilization rate. Therefore, different lubricants should be selected for different purposes. Common linear guides require lubricants that meet multiple conditions simultaneously, including high stability, corrosion resistance, wear resistance, low friction, and high oil film strength.
According to the type of lubricating oil, it can be divided into grease lubrication and oil lubrication. Generally, different types of grease should be selected based on the conditions and environment for grease lubrication：
Grease lubrication
Linear guides must be lubricated with the lithium soap based grease before installation. After the linear guides is installed, we recommend that the guides be re-lubricated every 100 km. it is possible to carry out the lubrication through the grease nipple. Generally, grease is applied for speeds that do not exceed 60 m/min faster speeds will require high-viscosity oil as a lubricant.
Oil lubrication
The recommended viscosity of oil is about 30~150cSt. The standard grease nipple may be replaced by an oil piping joint for oil lubrication. Since oil evaporates quicker than grease, the recommended oil feed rate is approximate 0.3cm3/hr.
The above are tips for lubricating linear guides. It is reminded that when choosing lubricating oil, it should be decided according to the work purpose to ensure better use.
