Core advantages of THK DK6310-4 ball screw
High precision: The grinding process ensures that the lead error is extremely small (within ±0.01mm/300mm), and the THK DK6310-4 ball screw is suitable for precision positioning.
High rigidity: The double nut preload structure of the THK DK6310-4 ball screw can withstand high axial loads (such as the DK series rated dynamic load of up to tens of kilonewtons).
Long life: With optimized ball contact angle and material processing, the life of the THK DK6310-4 ball screw can reach tens of millions of reciprocating motions.
Low noise: The ball circulation path is smooth, and with precision processing, the operating noise is lower than that of ordinary screws.
Energy saving and high efficiency: The friction coefficient is low (about 0.003~0.01), and the transmission efficiency of the THK DK6310-4 ball screw is as high as more than 90%, reducing drive energy consumption.
