Description

In HC20 Hydraulic Rock Drill (or Hydraulic Drifter) systems, the Upper flange 86668753 is a “critical upper structural connector”—it links the drill’s upper housing to components like the hydraulic valve block, while sealing hydraulic interfaces to prevent oil leakage. As a long-service-life part, its integrity directly affects the drill’s safety: a cracked or deformed flange can cause oil leaks (wasting 3-5 liters monthly) or component misalignment, leading to unplanned downtime.

With over a decade in mining maintenance, I’ve seen generic upper flanges fail early: most use thin low-strength steel (tensile strength < 500 MPa) that cracks under vibration in 1500-1800 hours. Their imprecise bolt holes (tolerance ≥ ±0.01mm) also require on-site modifications, increasing maintenance time.
This Upper flange 86668753, as a genuine OEM part, meets Montabert’s strict standards:
  1. Durability: Made of heat-treated alloy steel (tensile strength ≥ 650 MPa), it resists cracks and deformation for long-term use.
  2. Precision: Bolt holes and sealing surfaces are machined to ±0.003mm tolerance, ensuring seamless assembly and no leaks.
  3. Corrosion resistance: Zinc plating protects against damp underground or dusty surface environments.
Since it’s designed for long-term use, you only replace it when damaged—cutting maintenance costs. Its short delivery (no 2-3 week waits like generics) ensures quick replacement if needed. With competitive pricing, this flange is essential for mines prioritizing reliability and cost-efficiency, keeping HC20 stable for years.
