Technical Part Definitions for Heavy Machinery

• Bushing: A removable metal lining used to reduce friction and wear. It is often installed in connection points to protect pins and shafts.                
  Example: Sandvik DD321 feed slide bushing (EN), 山特维克DD321进给滑块衬套 (CN), Втулка подающей каретки Sandvik DD321 (RU).

• Rock Drill Piston: The reciprocating component inside a rock drill’s percussion unit that delivers impact energy to the drill bit. It is located within the rock drill hammer.                
  Example: Epiroc Boomer L2C rock drill piston (EN), 英格索兰Boomer L2C凿岩机活塞 (CN), Поршень перфоратора Epiroc Boomer L2C (RU).

• Crawler Chain: The articulated chain of links and pins that forms the track for a tracked vehicle, distributing the vehicle’s weight. It is mounted on the undercarriage.                
  Example: Atlas Copco SmartROC D65 crawler chain (EN), 阿特拉斯科普柯SmartROC D65履带链 (CN), Гусеничная цепь Atlas Copco SmartROC D65 (RU).

• Hydraulic Cylinder Seal Kit: A collection of seals and gaskets used to prevent fluid leakage in a hydraulic cylinder. It is installed within the piston and rod end of the cylinder.                
  Example: Sandvik DT1130C hydraulic cylinder seal kit (EN), 山特维克DT1130C液压缸密封件工具包 (CN), Комплект уплотнений гидроцилиндра Sandvik DT1130C (RU).

• Main Bearing: A bearing that supports and allows the crankshaft to rotate freely. It is located in the engine block's main bearing saddles.                
  Example: Atlas Copco MT6020 main bearing (EN), 阿特拉斯科普柯MT6020主轴承 (CN), Коренной подшипник Atlas Copco MT6020 (RU).

• Pressure Relief Valve: A safety valve that limits the pressure in a hydraulic system by diverting excess fluid. It is installed in the hydraulic circuit, often near the pump or cylinder.                
  Example: Sandvik Pantera DP1500i pressure relief valve (EN), 山特维克Pantera DP1500i泄压阀 (CN), Предохранительный клапан Sandvik Pantera DP1500i (RU).

• Hydraulic Pump: The component that converts mechanical power into hydraulic energy, moving fluid through a hydraulic system. It is mounted on the engine or power take-off.                
  Example: Epiroc ROC L8 hydraulic pump (EN), 英格索兰ROC L8液压泵 (CN), Гидравлический насос Epiroc ROC L8 (RU).

• Steering Knuckle: A part of the front axle assembly that contains the wheel spindle and is connected to the tie rod and steering gear. It is a key component of the steering system.                
  Example: Atlas Copco Boomer 282 steering knuckle (EN), 阿特拉斯科普柯Boomer 282转向节 (CN), Поворотный кулак Atlas Copco Boomer 282 (RU).

• Propeller Shaft: A mechanical component for transmitting torque and rotation, used to connect other components of a drive train that cannot be connected directly. It is typically found in the driveline.                
  Example: Sandvik TH663 propeller shaft (EN), 山特维克TH663传动轴 (CN), Карданный вал Sandvik TH663 (RU).

• Water Pump: A pump that circulates coolant fluid through an engine's cooling system. It is mounted on the front of the engine, connected to a belt system.                
  Example: Epiroc FlexiROC T40 water pump (EN), 英格索兰FlexiROC T40水泵 (CN), Водяной насос Epiroc FlexiROC T40 (RU).
