Abstract

The present invention has the object of providing a grease composition for a mounter that exhibits excellent stability to mechanical shearing, and excellent mixing stability, a guiding device for a mounter that includes the grease composition, and a mounter that mounts the guiding device. A grease composition for a mounter includes a base oil and a thickening agent, has a worked penetration of 200-400, a dropping point of greater than or equal to 220° C., and a worked penetration change during a roll stability test of 0 to less than or equal to +100.

Claims

1. A grease composition for a mounter comprising a base oil and a thickening agent, the grease composition having a worked penetration of 200-400, a dropping point of greater than or equal to 220°

C., and a worked penetration change during a roll stability test of 0 to less than or equal to +100.

2. The grease composition according to claim 1, wherein the base oil contains at least 60 mass % of a poly α

-olefin.

3. The grease composition according to claim 1 wherein the thickening agent is a lithium-complex soap.

4. A guiding device for a mounter including the grease composition according to claim 1.

5. The guiding device for a mounter according to claim 4 wherein the guiding device operates with a maximum displacement speed of at least 1 m/s, or a maximum acceleration of at least 10 m/s².

6. A component mounter comprising the guiding device according to claim 4.
