High Rigidity Ball Screw THK DIK2805-8 C5 Ball Screw

Selection Guide: Key Parameters

Critical selection factors include:
① Shaft Diameter: 28/32/36/40/50/63mm (load capacity increases with diameter);
② Lead: Affects speed and resolution (smaller lead = higher resolution);
③ Preload Grade: Light (micro-motion), medium (general), heavy (impact loads);
④ Accuracy Class: C0-C7 (DIK typically uses C5/C7). Match to equipment positioning requirements.

When installing THK DIK2805-8, there are strict requirements on the flatness and rigidity of the installation datum. The flatness error of the installation surface must be controlled within the specified range, otherwise, it will cause additional torque during the operation of the screw, aggravate wear and reduce accuracy. At the same time, the coaxiality between the screw shaft and the drive motor also needs to be calibrated. Excessive deviation will increase operating noise and vibration.

When installing on precision sliding table equipment, it is usually necessary to use a level and a dial indicator for debugging to ensure that the installation datum meets the requirements, laying a foundation for the stable operation of DIKDIK2805-8.
