Atlas Copco Parallel Key Part Number 0337715200 is a genuine original transmission connection component specifically designed for the GA series screw air compressors. It precisely fits the connection requirements of key transmission parts in GA models, such as the motor shaft and reducer input shaft, as well as the main rotor shaft and coupling. As a core connecting element in the power transmission system of GA models, this parallel key primarily serves two critical functions: First, it achieves circumferential fixation between the shaft and transmission components on the shaft (e.g., couplings, gears). Through its precise fit with the shaft groove and hub groove, it stably transmits the power output from the motor to subsequent transmission components, ensuring torque transmission without slippage or loss, thereby guaranteeing the continuity and stability of power transmission during GA model operation. Second, it assists in positioning the radial placement of components on the shaft, working in conjunction with bearings, shaft shoulders, and other parts to limit radial displacement of transmission components. This prevents transmission noise or component wear caused by misalignment, maintaining the precise fit state of the transmission system.
As a genuine original part, the production of this parallel key strictly adheres to Atlas Copco's high-standard quality system. It is manufactured from high-strength alloy structural steel through precision machining, offering excellent shear strength and wear resistance. It can withstand torque impacts during long-term high-load operation of GA models, avoiding key breakage or deformation due to insufficient material strength. Its dimensional parameters, such as key width, key height, and key length, fully match the specifications of the corresponding shaft grooves and hub grooves in GA models. The surface roughness and fit accuracy meet original factory assembly standards, allowing for a tight fit during installation without additional adjustments, ensuring that power transmission efficiency complies with GA model design requirements. Through pre-delivery dimensional accuracy inspections, hardness tests, and shear performance verifications, this parallel key provides reliable connection assurance for the transmission system of GA series air compressors. It helps maintain efficient power transmission, reduces故障停機(jī) caused by transmission connection issues, extends the service life of transmission components, and ensures long-term stable operation of the entire machine.
