NTN CORPORATION will begin mass production in November of SP-1 grease for machine-tool main-spindle bearings. The dmn value has reached 2.3 million for grease-filled bearings, with the aim of improving high-speed rotation performance.
NTN CORPORATION is reportedly scheduled to begin mass production in November of SP-1 grease for machine-tool main-spindle bearings. The move to mass production is viewed as a step toward practical application.
The dmn value of bearings filled with SP-1 grease has reportedly reached 2.3 million, indicating improved performance at high rotational speeds.
The grease is expected to be used as an alternative to air-oil lubrication and could provide a new option for the lubrication design of main-spindle bearings.
