Prelubricated Stock Sheet and Method and System for Making the Same
20170056952 · 2017-03-02 ·

A pre-lubricated stock sheet and a method and system for making the same are described. The pre-lubricated stock is generally in a coil wound form. The stock sheet can have opposing first and second sheet surfaces joined together by opposing side edges and opposing ends. Typically, the first and second sheet surfaces are substantially smooth and planar, wherein the sheet has 3 mg/foot.sup.2/side to about 200 mg/foot.sup.2/side of a solid lubricant having a melting temperature from about 80 to 212 degrees Fahrenheit. Moreover, the opposing side edges usually are substantially free of the solid lubricant. In some configurations, the stock sheet is an aluminum stock sheet, more particularly an aluminum can stock sheet. Furthermore, the lubricant can be in some configurations a food grade lubricant, that is qualifies a low volatile organic compound under one or more of municipal, state and federal governing authorities.

ULTRAVIOLET CURABLE RESIN COMPOSITION, SLIDING MEMBER, AND METHOD FOR PRODUCING SLIDING MEMBER

There is provided a resin composition for a machinable liner of a sliding member. An ultraviolet curable resin composition for a self-lubricating liner contains a (meth)acrylate compound having an isocyanuric acid ring represented by the following formula and PTFE as a solid lubricant. In the formula (1), X is a group which contains an acryloyl group and is composed only of C, H, and O. Y and Z are groups each composed only of C, H, and O. PTFE is contained in an amount of 10 to 50% by weight with respect to a total amount of the ultraviolet curable resin composition. The ultraviolet curable resin composition is suitable for a self-lubricating liner 24 of a spherical bearing 20 having an outer race 22 and an inner race 26.
