Jialede's Solution: Perfluoropolyether Grease for Air Compressor Needle Bearings

Recently, Jialede developed a wide-temperature-range high-performance product based on perfluoropolyether (PFPE) grease to address the harsh operating conditions of needle bearings in customers' air compressor main units. This grease maintains stable lubrication in environments with large swing angles, 1500 rpm oscillations, and long-term high loads of 2000 N.

Needle bearings in air compressor main units are typically subjected to frequent oscillations and high-rhythm stress, and during long-term use, they experience operating temperatures exceeding 100°C, even reaching 220°C under instantaneous extreme conditions. Ordinary greases are prone to problems such as high-temperature evaporation, shear thinning, or low-temperature hardening under these conditions. Jialede's PFPE grease possesses excellent high-temperature oxidation resistance, low-temperature fluidity, and extremely strong mechanical stability, covering a wide operating range from -40°C to 280°C.

The customer's validation program includes:

* Low-temperature performance testing: After the sample is left to stand at -40°C for 8–24 hours, the rheological state of the grease is observed and the compressor starting current is measured.

* High-temperature durability testing: Continuous validation for at least 3 months under operating conditions exceeding 100°C.

Approximately 50g of grease is required for each compressor's needle roller bearing.

To meet the above requirements, we have provided 200g samples of perfluoropolyether grease for customer testing. Jialede adheres to a real-world operating condition-oriented approach, optimizing product performance item by item from oil film formation and shear stability to low-temperature starting torque, ensuring it meets the long-term reliability requirements of OEMs.

In the future, Jialede will continue to work closely with OEMs to provide reliable perfluoropolyether lubrication solutions for compressors operating in high-speed, high-load, and high-temperature environments, helping customers improve equipment efficiency and extend service life.
