A few years ago while perusing Timken's web site lubrication documents, I remember an article talking about a grease's extreme pressure capability (Timken ok load) in regards to wheel bearing lubrication. The article suggested that at some point, too high Timken ok load was detrimental to good wheel bearing lubrication. The article did not give a specific cut off point. Most wheel bearing grease has a Timken ok load of approximately 50 to 80 lbs. The Mystic JT 6 high temp. grease tends to be on the high end at about 80 lbs. Timken ok, while most wheel bearing greases are around 50 to 65.
This Eaton grease with a Timken ok load of 110 pounds seems much higher than other wheel bearing greases.
For the life of me, I cannot locate the article at the Timken site. My comments are based on memory and I am not a grease expert. Just tossing this out for discussion.
