The development of a metallurgical hydraulic cylinder body air over oil cylinder necessitates careful consideration of various parameters. The scale of the cylinder must be optimized to support the needed load and pressure. Additionally, the material option is crucial, as it directly affects the cylinder's robustness and immunity to wear and tear.

Piston rod bearings are crucial components in internal combustion engines, facilitating smooth oscillation between the piston and the connecting rod. Their efficacy heavily influences engine durability. The design of these bearings involves intricate considerations of materials, geometry, and lubrication to withstand the harsh operating conditions
