How JetLube AP-5 high-temp grease protects bearings from 0°F to 550°F is the focus of this episode — a deep dive into the MoS2-fortified, bentone clay-thickened compound that keeps kiln bearings, crusher pivots, and oven conveyors running where conventional soap-base greases turn to liquid and fail.

The defining feature of AP-5 is its organo clay (bentone clay) thickener, which carries a dropping point of None under ASTM D-566 — meaning it never melts. That non-melting characteristic underpins the full operating range of 0°F (-18°C) to 550°F (288°C), with a flash point exceeding 560°F (293°C) per ASTM D-92 and a calculated autoignition point above 680°F (360°C). For furnace-adjacent equipment, oven conveyors, and h ...
