Ring nut for Terex BT4792

The ring nut, part number 226845, serves as a fastener within the topping cylinder assembly of the Terex BT4792 crane. It is used to secure the internal components of the cylinder, ensuring that the assembly remains held together during the hydraulic operation of the boom. By maintaining the mechanical position of these internal parts, the nut supports the cylinder's ability to control the elevation and angle of the boom system effectively.

This component is specifically engineered for the Terex BT4792 model. It is designed to fit the dimensions and thread requirements of the topping cylinder housing, providing a secure attachment point for the cylinder head or gland. Proper installation ensures that the internal seals and pistons remain correctly positioned within the cylinder tube.

In hydraulic cylinders, ring nuts or gland nuts are used to retain the rod seal and wiper assembly or to secure the cylinder head to the barrel. They provide the necessary clamping force to withstand the internal hydraulic pressures generated during machine operation, preventing the separation of cylinder components and maintaining the seal required for fluid containment.
