About Sandvik 204 639 08 LIMIT BUSHING
This precision-machined bushing is a critical wear component in the Sandvik DS410-C drilling system. Bushings reduce friction between rotating and stationary parts, significantly extending the service life of the entire ZOOM CYLINDER assembly. Regular inspection and timely replacement of worn bushings prevents costly damage to mating components and reduces unplanned downtime in mining operations.
This is an OEM-compatible aftermarket replacement part for the Sandvik DS410-C (DS410-C). Also compatible with Tamrock branded equipment of the same model series. BK Drilling supplies this part with fast worldwide shipping and competitive pricing.
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.
