The Sliding piece (OEM Part No. 3128314344) is a spare part compatible with Boltec 235 , boltec-MC and boomer-md underground drilling equipment. Manufactured from durable alloy steel, it is classified as a wear part for the drill rig sliding mechanism at the linear slide fitting position. It bears continuous reciprocating friction during feed beam travel, isolating metal-to-metal contact and lowering abrasion of matched structural parts. The wear-resistant alloy steel material effectively reduces sliding resistance, avoids jamming faults and extends the maintenance cycle of mining rig sliding systems.
