Abstract: A belt conveyor, a collecting hopper and a screw conveyor are sequentially disposed below a chute for feeding hydrogenated petroleum resin pellets from a pelletizing portion. Even when the hydrogenated petroleum resin pellets fed onto the belt conveyor are dropped off or scattered, the hydrogenated petroleum resin pellets can be collected by the collecting hopper that is located below and can be securely transferred to an outside by the screw conveyor.

Abstract: A bearing grease contains a base oil and a thickener. The base oil is a base oil mixture containing a polyalphaolefin and an ester. The bearing grease is used in an atmosphere of a fluorine compound refrigerant containing no hydrogen. A bearing using the bearing grease does not cause elution of grease for a long time. Further, since there is no need for a collecting system unlike lubricating oil, the arrangement around the bearing can be made compact. Thus, the bearing can be easily applied in a form of an energy recovery equipment to a vehicle or various industrial machineries.
