We newly developed the prototype calcium complex grease (Cx-S) which delivered a better temperature performance than traditional calcium complex greases and could keep its structure even over 200°C. This was achieved by combining the common calcium complex thickener technology with a new concept. In this report. the bearing life of several grease types was evaluated by ASTM D 1741. https://foldlyers.shop/product-category/iphone-xr-11/
