GC Grease 350
GC Grease 350 is a high-performance urea-based grease specifically designed for couplings from Kyodo Yushi (Japan), formulated with mineral oil, high molecular polymer and urea thickener. Developed for harsh conditions requiring high load, high rotational speed and strong centrifugal force, it features exceptional leak resistance, splash resistance, extreme pressure (EP) and wear resistance, long-lasting lubrication performance, good material compatibility and stable batch quality. Ideal for industrial couplings, universal joints and heavy-duty transmission components, it provides reliable long-term lubrication and protection for steel, papermaking, wind power, mining, marine and heavy machinery industries.
