Kaeser 48-241.3 Drive Coupling Assembly

The 48-241.3 drive coupling is a BoWex Elastic 48 HE flexible coupling element designed for Kaeser rotary screw air compressors. It features a steel flange conforming to SAE 7.5 dimensions with an outer diameter of 241.3 mm and a pilot diameter of 24.05 mm. The coupling utilizes a high-flexibility polyamide elastic element to compensate for shaft misalignment and dampen torsional vibrations between the prime mover and the compressor airend. This component serves as a direct replacement for Kaeser part numbers 48-241.3 and 482413. It is engineered to restore the motor-to-compressor power transmission function on Kaeser M43, M50, and M57 compressor models. The steel flange construction ensures durability under continuous industrial duty cycles. Installation requires alignment verification per OEM specifications to ensure optimal service life of the elastic element and connected shaft bearings.
