This heavy-duty overhaul sealing kit is specially customized for FURUKAWA HCR9DS hydraulic top hammer rock drill, widely matched to crawler drilling rigs for mine blasting, road construction and quarry engineering. It contains complete impact cylinder cup seals, main diaphragm, O-rings, dust seals, gaskets and PTFE backup rings for full drill disassembly maintenance.
Adopting imported high-strength PU, wear-resistant NBR and FKM fluororubber as core raw materials, the kit boasts outstanding impact resistance, hydraulic oil resistance, abrasion resistance and high-temperature aging resistance. It fully replaces original Furukawa sealing spare parts, effectively solves common faults including diaphragm rupture, cup seal oil leakage, internal pressure loss and weak impact force, and greatly extends continuous service life under high-frequency heavy impact working conditions.

Fully dimensionally consistent with original FURUKAWA HCR9DS rock drill sealing parts, matches OEM part numbers FURU-HCR9DS and HD609-01008. No trimming or modification required, one-to-one direct installation to reduce assembly difficulty.
Core vulnerable parts adopt high-toughness imported PU leather cup and thickened FKM energy storage diaphragm, paired with PTFE anti-extrusion backup rings. The material resists hydraulic oil corrosion, high-frequency impact fatigue and high-temperature aging, maintaining stable sealing performance at -25°C to 120°C.
All components pass strict 26MPa dynamic impact pressure fatigue testing. Effectively stops internal cylinder oil seepage, diaphragm burst and external oil leakage, stabilizes drill impact power and avoids pressure drop during continuous rock drilling.
Covers all sealing consumables required for full machine disassembly maintenance of HCR9DS rock drill, integrating leather cup, diaphragm and all auxiliary sealing rings in one set. Complete matching parts shorten on-site repair time and cut equipment maintenance cost.
Every set of seal kits undergoes air tightness, high-frequency impact and thermal aging tests before delivery, fully meets Furukawa OEM manufacturing standards, ensuring stable long-term operation under harsh mining and construction environments.
Suitable for all engineering equipment equipped with FURUKAWA HCR9DS hydraulic rock drill: • Surface crawler drilling rigs (HCR900-DS, HCR9DS series) • Quarry bench drilling equipment • Mine blasting hole drilling machinery • Highway & tunnel rock drilling rigs • Hydraulic top hammer drilling systems • Heavy-duty mobile rock excavation machinery
