PETAMO GHY 441 uses a synthetic ester oil and a polyurea thickener. Mixing it with incompatible thickeners (like lithium or calcium complex) can cause the grease structure to collapse, leading to oil bleed and catastrophic bearing failure. Always thoroughly pre-clean bearings prior to initial application.\u003c\/p\u003e\r\n  \u003c\/div\u003e\r\n  \u003cdiv class=\"koeed-faq-item\"\u003e\r\n    \u003cdiv class=\"koeed-faq-q\"\u003eWhy choose PETAMO GHY 441 over PETAMO GHY 443?\u003c\/div\u003e\r\n    \u003cp class=\"koeed-faq-a\"\u003eWhile both share the identical ester\/polyurea base and 180 °C temperature rating, \u003cstrong\u003eGHY 441 has a softer consistency (NLGI 1 vs NLGI 2)\u003c\/strong\u003e.
