Lock Rubber

Built for continuous heavy-duty service, the Lock Rubber (OEM 550 643 86) is a premium aftermarket component for rock drilling and drifter rigs operating in extreme conditions. It locates and secures mating parts, stopping unwanted movement and keeping the assembly correctly aligned under load.

Made from hardened, wear-resistant steel to precise tolerances, it resists shear, vibration and impact while providing secure, repeatable retention. As an alternative spare part, it offers full functional interchangeability at a competitive cost, without compromising performance or reliability.

Backed by Delkom’s expertise in alternative rock drilling and drifter equipment, this part reflects the quality we export to over 100 countries. Reach out for availability, bulk pricing and technical support.
