Detailed description
Overview:
AVIC Hangte ZL7-2 low-temperature grease is a high-performance grease designed for aviation, precision instruments and wide-temperature mechanical equipment. It has excellent low-temperature performance and chemical stability. The operating temperature range is -60℃~ +120℃.
Performance characteristics:
◎Excellent ultra-low temperature performance: still maintain lubricity at -60℃, suitable for extremely cold environments
◎Good wide temperature adaptability: still stable at high temperatures (120℃), high dropping point, and resistance to thermal oxidation
◎Good mechanical stability: stable structure after shearing, extending service life
◎Good water and rust resistance: not easy to emulsify, suitable for humid environments
Recommendation:
Protection and lubrication of aircraft operating rod systems, lubrication of rolling bearings and sliding bearings of various mechanical equipment.
Execution standard: Q/SY YM 0029-2000
