HC50 and HC109 spline sleeves are made of high-quality alloy steel material, which has excellent strength and wear resistance and can withstand high-intensity impact and torsion. In rock drilling operation, the equipment often faces complex rock structure and high intensity impact, and the spline sleeve made of high-quality alloy steel material is able to transmit power stably and ensure the stability and reliability of the equipment.

Thanks to the use of high-quality alloy steel or other special materials, HC50 and HC109 spline sleeves have excellent corrosion and wear resistance, and can be used for a long time in harsh working environments without deformation or damage. Whether under severe conditions such as high temperature, high humidity and high pressure, or in frequent shock and vibration environments, the spline sleeve can maintain stable performance, ensuring the normal operation and safety of the equipment.
