1. Why Every Cold-Sky Flight Starts with 7023B Aerospace Grease Low-Temp
When temperatures plunge to ‑55 °C, ordinary greases solidify and bearings freeze. 7023B Aerospace Grease Low-Temp stays silky, turning Arctic starts into smooth take-offs. Discover the seven cold-proof benefits that make this yellow-green grease the silent co-pilot of aviation fleets from Harbin to Helsinki.
2. What Exactly Is 7023B Aerospace Grease Low-Temp?
Formulated by Sinopec’s Great Wall R&D centre, 7023B is a di-ester synthetic oil thickened with a lithium-complex soap, boosted by anti-oxidant, anti-rust and structure-improving micro-additives. The result is a low-temperature aviation lubricant certified to ISO 6743-9 that protects ball bearings, gears and control-surface pivots down to –55 °C and up to 120 °C.
3. Seven Powerful Cold-Proof Benefits
-
Unbeatable pour point at –55 °C – bearings spin freely after 12 h cold soak.
-
180 °C drop point – survives sudden heat spikes during braking.
-
Excellent mechanical stability – 10 000-stroke penetration change < 8 %.
-
Superior oxidation life – 500 h @ 120 °C, pressure-drop < 35 kPa.
-
Outstanding noise reduction – lowers micro-vibration by 3 dB compared with MIL-PRF-23827.
-
Superb water wash-out resistance – 1.2 % loss in ASTM D1264, ideal for de-icing spray zones.
-
Wide material compatibility – safe on PEEK, Viton, Cadmium and silver-plated races.
4. Where 7023B Shines – Real-World Applications
-
Aviation motor bearings & gears – turbofan starter-generators, helicopter servo motors.
-
Control-surface fulcrums – aileron, rudder and flap linkages.
-
High-speed ball bearings – 30 000 rpm gyroscopes, cryo-pumps.
-
Civilian upgrades – automotive windshield-wiper gearboxes in northern Sweden.
-
Special environments – UAV launchers on plateaus at 5 000 m altitude.

6. How to Apply 7023B for Maximum Life
-
Clean bearing with CRC aviation solvent (DoFollow).
-
Pack 30 % of internal void – do not over-grease.
-
Rotate shaft slowly to distribute film.
-
Operate 5 min @ idle, then inspect for even meniscus.
-
Re-grease after 1 000 flight hours or 12 months, whichever comes first.
7. Storage & Shelf Life
Store cartons below 30 °C, RH < 60 %. Unopened kegs last 5 years; opened tins, 1 year if resealed with Sinopec UV-proof lid (internal link). Keep away from halogens and strong oxidisers.
8. Sustainability & Compliance
7023B is free of PFAS, lead and cadmium. It meets ISO 6743-9 XDHA, GB 2361-90 and RoHS 2.0.
