This locknut secures bearings and other components on a shaft against an adjoining shoulder, providing axial fixation once tightened to the required position. Main dimensions follow DIN 981, with a width of 25.0 mm and a net mass of 2.619 kg, allowing correct fit and load transfer along the shaft thread. The locknut KM32 is used together with a matching lock washer to prevent loosening under vibration or rotation, keeping the fixed component correctly positioned during operation. Its standardized dimensions to DIN 981 ensure compatibility with corresponding shaft threads sized for this designation, making installation straightforward for a fitter following the standard mounting sequence.
