Krytox XHT/BDX High Temperature Grease 2oz Tube

Krytox XHT-BD series oils are special extreme high temperature greases with low oil evaporation and are thickened with a non-melting thickener to allow use at temperatures above the melting point of common greases. They have excellent lubrication over a broad temperature range. Krytox XHT-BD series greases are nonflammable and chemically inert. Krytox allows extended lubrication intervals and longer equipment life.

Krytox XHT-BD greases are designed for use where the temperatures are in the 288 ° (500 °) range and higher, where there is a danger of melting the standard PTFE thickener. This grease uses a special non-melting high temperature thickener. The base oil is an extremely viscous oil that provides good viscosity and lower evaporation at high temperatures. Krytox XHT-BD greases are for use in low speed bearings or in pillow housings and will shear at high speeds, causing loss of oil in sealed bearings. The oil in the grease can begin to slowly degrade at temperatures above 330°C (626°F) and this will occur at an increasing rate as temperatures increase. Relubrication could be required at these temperatures to achieve optimum life.
