JCB Steel Kingpost Bushing 35mm - AZERI PARTS
Steel kingpost bush by AZERI PARTS, designed for the boom swing system (kingpost) in JCB mini excavators. This component is installed in the kingpost sockets to ensure precise pin guidance and minimize friction during attachment swing movements. The bushing is made of heat-treated steel, providing optimal surface hardness and resistance to cracking under heavy loads.
Specifications and Technical Features:
- Inner Diameter: 35 mm.
- Material: Hardened steel with lubrication channels for superior grease distribution.
- Construction: Precision-manufactured to ensure easy installation in the machine's socket.
- Application: Boom swing system (kingpost).
Compatibility with JCB Mini Excavators:
| C Series (Conventional) |
15C, 16C, 19C, 26C, 31C |
| Z Series (Zero Tail Swing) |
18Z, 25Z, 30Z |
Technical Advice: Kingpost play is a natural result of operation; however, ignoring it leads to "wallowing out" the sockets in the machine's structure, which requires costly refurbishment. When installing bushing, thoroughly clean the socket and check that the grease lines are clear. Regular greasing creates a protective layer that significantly reduces the steel-on-steel wear process.
