Bearings are essential in any machinery, serving to reduce friction and support rotating parts. In a jaw crusher, there are generally two types of bearings involved the main bearings that support the eccentric shaft and the bearings that support the pitman assembly. High-quality bearings are critical for the efficient functioning of the machine, and regular maintenance is necessary to ensure longevity and optimal performance.

At its core, submarine hammer drilling employs a powerful hammer mechanism to drive a drill bit into the seabed. The system utilizes both air and water pressure to deliver repeated impacts on the drill bit, which enables it to break through hard rock formations or sediments that might hinder installation efforts for marine infrastructure. The design of the hammer ensures that the energy is efficiently transmitted to the drill bit, allowing it to operate at significant depths.

The DTH hammer operates through a system of compressed air. High-pressure air is directed down the drill string, powering the hammer at the end of the drill bit. The hammer strikes the bit with considerable force, fracturing the rock immediately beneath it. As the bit penetrates further, the broken rock is then cleared from the hole by the same air stream, allowing for continuous drilling without the interruptions often associated with other drilling methods.
