Frequently asked questions
What does a bushing do in a drilling machine?
A bushing acts as a wear-resistant liner that reduces friction between moving and stationary parts. It protects more expensive components from direct contact wear, extends service intervals, and maintains precise alignment of rotating elements in drilling equipment.
How often should bushings be replaced?
Bushing replacement intervals depend on operating conditions, but typical mining applications require inspection every 500-1000 operating hours. Signs of wear include increased play or vibration, unusual noise, and visible scoring or deformation of the bushing surface.
