1. The purpose of lubrication

For the linear guide rail lubrication is intended to prevent metal to metal contact between the linear guide rail surface and interior of the rolling body, reduce friction and wear,prevent heating and sintering.When the film roll contact surface of the rolling element raceway surface and formed components, also has a reduced contact stress due to the load generated by the effect. Manage lubrication, fully form a film on the linear guide to ensure the reliability is very important.

2, the choice of lubricant

To give full play to the performance of the linear guide, it is necessary according to the linear guide in the form of load, speed, etc., to choose the right type of lubricant and lubrication methods.However, compared with the linear guide rail and the sliding guide rail he dependence of the lubricant is extremely small, so small to the oil, add the interval too long, can play to reduce the burden of maintenance margin management. Linear guide lubricant used can be divided into two kinds of lubricants and lubricating oils.

3,the grease lubrication

Linear Guides general use lithium soap grease (JIS consistency No. 2), for heavy-duty, it is recommended to use add with extreme pressure additives grease.In a clean environment and the high vacuum environment,can use lubricating grease base oil or lithium other soap and other low dust, volatile using synthetic oil as. Used in these environments, linear guide in line with the conditions of use at the same time, must fully consider how to satisfy the lubrication performance.

4. Grease filling gap

Even high-quality grease, its performance will be run over time and aging, and therefore essential for proper supplement. Grease filling interval because conditions vary, usually six months time, for long-distance reciprocating machinery, recommended three months plus one grease.

5, grease filling method

Fill grease from the grease nipples and other devices to fully inject grease until the old grease discharge date. After running-greasing operation, the excess grease will be discharged linear guide, to discharge grease removal before starting operation.

Standard grease filling volume is the volume of the internal space of the linear guide about 1/3 to 1/2, as a example, when the initial grease lubrication from the mouth, there will be some loss in the filling path, it is necessary to consider the loss factor.
