Product Description
The 21T-70-73170 Link Bushing is a cylindrical metal sleeve pressed into the track link of Komatsu PC1600-1 excavators. It provides a wear-resistant bearing surface between the track link and the pin, reducing friction and wear during track articulation. By protecting both the link and pin from direct metal-to-metal contact, the bushing extends the service life of the track chain and maintains proper track tension and alignment.
