Carriage bushing with part number 332/G0942 from the GX-AFTER offer. It is a specialized sliding bush made of high-grade bronze, designed for JCB construction machinery. This element is installed in the rear excavator system (kingpost carriage), where it is responsible for smooth rotation and movement of the arm, reducing friction between the pin and the machine body.
GX-AFTER bushings made of bronze are characterized by excellent sliding properties and resistance to seizure. This material is "softer" than the steel pin, so the bushing wears out (as a consumable part), protecting expensive structural elements of the machine.

Before purchasing, we recommend verifying the dimensions of the old bushing, as JCB machines use different joint variants depending on the serial number.
Bushing 332/G0942 works with a steel pin. When replacing the bushing, it is also recommended to verify the condition of the pin – if it is worn, the new bushing will wear out instantly. Also remember about shims and high-quality grease.
Ignoring play on the excavator carriage leads to ovalization of the seats in the frame casting. Regenerating worn holes (line boring) is a very expensive and time-consuming process. Regular replacement of bronze bushings is the cheapest way to keep the machine in working order.
The bushing is responsible for the precision of the rear arm operation.

Bronze is a "self-lubricating" material and softer than steel. In the absence of grease, the bronze bushing will wear out, not the expensive pin or carriage seat. It acts as a mechanical fuse.
Bushing 332/G0942 is located in the so-called kingpost or carriage, which is the element that slides along the rear frame and allows the entire digging attachment to rotate.
In some modern machines, composite or hardened steel bushings are used, but in classic designs like the JCB 3CX, bronze remains irreplaceable due to its resistance to seizure under high impact loads.
