20090170738 | LUBRICANT COMPOSITION - The present invention provides a lubricating composition, particularly a grease composition and a lubricating oil composition, containing an aralkylated diphenylamine and a phenol compound having a molecular weight of not less than 340 which are compounded into a base oil. The lubricating composition is hardly decomposed or volatilized even at high temperatures and has a long oxidation life so that the lubricating characteristics thereof can be maintained for a long period of time. | 07-02-2009 |
20090281008 | GREASE COMPOSITION - Provided is a grease composition with a long service life under high-temperature conditions, considerable low-evaporability, and incombustibility. | 11-12-2009 |
20100029524 | GREASE - Grease which includes a base oil containing at least 50% by mass of a specific diester compound of a glycol with a branched carboxylic acid, and a specific diurea compound as a thickener. The grease is excellent in low-temperature performance and has low oil separation tendency. In particular, when used in a rotation transmission device having a built-in one-way clutch, the grease can provide satisfactory clutch engagement performance (intermeshing) at low temperatures and is less apt to cause oil separation under high centrifugal force. | 02-04-2010 |
20100035779 | GREASE - A grease which comprises a base oil containing at least 50% by mass of a diester compound having a total carbon number of 28 to 40 and represented by the general formula (I): | 02-11-2010 |
20110041638 | GREASE COMPOSITION AND DIRECT-ACTING DEVICES WITH THE GREASE COMPOSITION - A grease composition includes: a poly-α-olefin having a kinematic viscosity at 40 degrees C. of 60 to 320 mm | 02-24-2011 |
20110143973 | GREASE COMPOSITION FOR MOUNTER, GUIDING DEVICE CONTAINING THE SAME, AND MOUNTER - 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. | 06-16-2011 |
20120065111 | BIODEGRADABLE LUBRICANT COMPOSITION - A biodegradable lubricating oil composition includes (A) an ester represented by a formula (1) below, the ester having a kinematic viscosity in a range from 300 mm | 03-15-2012 |
20120098269 | GREASE COMPOSITION - A grease composition includes a base oil and a thickener. The base oil includes a hydrocarbon-based synthetic oil at 40 mass % or more, and a component A at 20 mass % to 70 mass %, the component A having a kinematic viscosity of 70 mm | 04-26-2012 |
20130012416 | GREASE COMPOSITION - Provided are a grease composition which inhibits simultaneously a bearing wear and a fretting wear under a high load to make it possible to elongate a life of the bearing; a grease composition which can inhibit a fretting wear caused by a change in a load in a thrust direction in addition to an usual fretting wear caused by small vibration in an oscillating direction; and a grease composition which is excellent in low-temperature characteristics.
