Product Introduction K3V140DT-1CER: Durability Meets Efficiency for R290-7 31N8-10010 ExcavatorsTough job sites demand tough components, and the K3V140DT-1CER is engineered for the R290-7 31N8-10010’s harshest workflows. Peak pressure of 39.2 MPa amplifies the excavator’s breakout force, tackling compacted soil and rock with ease. Its semi-logarithmic swash plate maintains stability at low speeds, avoiding energy waste. Corrosion-resistant materials and tight tolerances reduce maintenance downtime, letting the R290-7 31N8-10010 stay productive longer—lowering operational costs.
