The Bushing (OEM Part No. 3128309273) is a spare part compatible with Boltec S, Boltec 235, Boltec-MC, Boltec-S, and Boomer-MD underground drilling rigs. Manufactured from bronze alloy or steel-backed composite materials, it is designed as a wear component for pivot and linkage support systems at the bushing assembly position. The bushing reduces friction between moving components, provides stable support, and protects connected parts from premature wear during continuous drilling and bolting operations. Its durable construction ensures reliable performance, extended service life, and smooth equipment operation in demanding underground mining and tunneling environments.
