Lubricating part C-Lube and lubrication mechanism4 features

Long-term maintenance-free running with oil in "C-Lube" only

The innovative capillary lubrication technology using the capillary action (capillarity) is the IKO's original technology. It enables long-term running of products without additional lubricant supply and maintenance. It can greatly contribute to the environment of the earth, either.

Lubricating part "C-Lube" and lubrication mechanism

"C-Lube" is made by sintering fine resin powders onto sleeves or plates. The sintered resin part contains lots of communicating pores. The pores can hold a great amount of lubricating oil due to the capillary action (capillarity). By assembling "C-Lube" in linear motion rolling guides, IKO has lined up the oil-minimum C-Lube maintenance-free series.

What is Lubricating Part C-Lube?

Lubricating Oil Supplying Mechanism of C-Lube Linear Way

Maintenance free

This endures running over 20,000 km without oil feeding with lubrication oil in the C-Lube only.
Furthermore, grease is pre-packed in the slide unit so long period maintenance free can be realized.

Durability test result


As lubrication oil in C-Lube is supplied by the amount necessary to maintain lubrication performance of the rolling guide, the consumption of lubrication oil is reduced and lubrication performance is maintained even when it run for a long period.

Oil supply test result


As C-Lube Linear Way and C-Lube Linear Roller Way are integrated with lubrication part C-Lube, their slide units are not long unlike types with external lubrication parts. Replacement of conventional parts is easy free from constraints of mounting space and stroke length.


C-Lube Linear Way and C-Lube Linear Roller Way do not generate slide resistance unlike lubrication parts external to the slide unit that make contact with the track rail. Driving force follow-up property is superior and energy is saved by improvement of accuracy and reduction of friction loss.
