Another important component of rock drill tools is the drilling machine itself. These machines are usually powered by compressed air or hydraulics, providing the necessary force to drive the drill bit into the rock. The drilling machine allows for precise control of the drilling process, ensuring accuracy and efficiency in tunnel excavation The drilling machine allows for precise control of the drilling process, ensuring accuracy and efficiency in tunnel excavation

Metal-cased oil seals are usually installed in a housing bore made of the same material. This allows for equal expansion and contraction of the materials during operation, preventing leakage. This type performs best when used in a steel housing.


Oil seals in the motor, including the engine and other critical components, are essential for maintaining the integrity and efficiency of the vehicle. These seals are designed to contain lubricating oil and prevent leaks, contributing to the smooth operation and longevity of the motor. Proper maintenance and replacement of oil seals in the motor are crucial for the reliability and performance of the vehicle's systems.
Once you have selected the most suitable seal available, considering the environment, temperature, shaft speed, pressure, lubrication availability, as well as the size, of course, the seal should be stored adequately and then fitted properly. Here are a few suggestions that could help:-
