For special applications trunnion bushings can be furnished constructed of Micarta to allow water lubrication or oil lubrication. In many dry grinding applications, or where heat is developed, the trunnion bearings can be furnished for water cooling. This system carries away the excess heat transmitted through bearings and protects them.

In most rolling mill applications, four-row tapered roller bearings are mounted with a loose fit on the roll neck. This enables quick roll changes. However, loose fits have the disadvantage that the inner rings turn on their seats under load. To reduce the effects of a loose fit, SKF bearings have a helical groove in the bore and/or lubrication ...

Grinding and Polishing Guide. Grinding should commence with the finest grit size that will establish an initially flat surface and remove the effects of sectioning within a few minutes. An abrasive grit size of 180-240 [P180-P280] is coarse enough to use on specimen surfaces sectioned by an abrasive wheel. Hack-sawed, bandsawed, or other rough ...
Arthritis of the neck orcervical osteoarthritis involves degenerative changes in the joints of the neck. These are often due to wear-and-tear of normal aging. As you grow older, the discs between the bones of the neck gradually wear down, lose lubrication, and become stiff.
