Description

Prepared for continuous-duty mining and tunnelling equipment maintenance, the Expanding Shaft (OEM 3125 1982 80) is a high-quality aftermarket component for Epiroc drilling and mining equipment. It creates a secure pivot connection in the boom or linkage by expanding into the mating bore and controlling joint play. Typical compatible references in the supplied list include BOLTEC 235, BOLTEC 235H and BOLTEC LC.

For long-term reliability, the part is exposed to high joint loads, oscillating movement, vibration and wear at the pivot interface. The expanding geometry and mating surfaces are produced to controlled dimensions so the joint can be tightened concentrically and serviced without altering the surrounding structure. A correctly installed expanding shaft helps reduce looseness, maintain pivot alignment and extend the useful life of the connected bores.

Supplied as a Delkom aftermarket alternative, this part is intended for professional maintenance and overhaul work. For ordering and cross-reference purposes, use Delkom reference 120 400 065. Delkom can support your maintenance team with availability checks, technical matching and volume pricing.
