Concentric and eccentric bushes serve as pivot or bearing points in machinery, allowing for smooth rotation or controlled motion. Concentric bushes maintain a uniform center, while eccentric bushes offer adjustable offset for alignment purposes. Both types reduce friction and wear between moving parts.

 Manufactured from hardened metals or specialized composites, these bushes can withstand heavy loads and repetitive motion. Proper lubrication and fitment are essential to prevent premature wear. Periodic inspection ensures they remain in good condition and maintain correct alignment.

 Choosing between concentric or eccentric bushes depends on the application's alignment and load requirements. In many cases, eccentric bushes help compensate for minor misalignments, improving machine performance. Ultimately, well-chosen bushes enhance reliability and reduce maintenance costs.
