- Hard chrome plasma coating on compression ring outer surface with high hardness and low friction coefficient, resist ring wear and cylinder scuffing under long heavy-load mining & pushing work of used loaders, service life extended by 60% compared with ordinary cast iron rings.
- Integral spiral spring inside oil ring evenly presses full circumference against cylinder wall without local gap for oil leakage, completely solve common faults of used loaders such as high oil consumption, black exhaust smoke and power loss, cut long-term fuel & oil purchasing cost.
- Tough ductile iron base withstands -40℃ cold start and 650℃ instant combustion high temperature, no fracture or elastic failure after temperature cycles. Fit high-temperature open mines in Africa/Middle East and cold construction sites, reduce overseas used loader failure reports.
