JCB Perforated Boom Bushing 46x48x89.3mm
Perforated bushing, specifically designed for the main boom pivot points in JCB machines. By utilizing internal perforation (special lubrication dimples), this component allows for grease storage, which drastically reduces friction and prevents seizing of the pin connection. Made of hardened alloy steel.

Technical Advice: Perforated bushings are a "smarter" solution than their smooth counterparts – the perforation acts as a backup lubrication system, which is crucial if the operator misses daily maintenance. When replacing a bushing, **always check the condition of the pin**. If the pin has visible ridges or scratches, the new bushing will wear out prematurely. Remember to thoroughly clean the boom seat before pressing in the new bushing and ensure that the grease channels from the grease nipples are clear.
