Chuck

Designed to meet the functional demands of modern drill-rig service, the Chuck (OEM N78127) is an aftermarket replacement for Soosan rock drilling and related equipment. It works within the drifter impact, rotation or shank-support system to keep energy transfer and tool guidance stable during drilling. It is cross-referenced for equipment including TD-51.

In service, this component is exposed to high-frequency impact, axial load, vibration, rotation and abrasive operating conditions. With wear-resistant material and precision-machined contact geometry suited to drifter service, the component is intended to install accurately and work predictably with adjoining parts. This helps preserve impact efficiency, shank alignment and reliable operation of the surrounding rock-drill assembly.

For workshops and fleet operators, this Delkom alternative offers a straightforward replacement route for the referenced Soosan application. Delkom part number 160 100 107 can be used for ordering, cross-reference checks and volume pricing.
