Abstract: An agent for forming a solid lubricating coating film on a thread portion of oil country tubular goods, in which a binder resin contains a prepolymer and a curing agent, the prepolymer is formed of one or more epoxy resins, 70 parts by weight or more of the prepolymer is contained with respect to 100 parts by weight of the binder resin, the epoxy resin constituting the prepolymer has an epoxy equivalent of 100 or more and 500 or less, the solid lubricant contains boron nitride (BN) in an amount of 80% by weight or more, BN has an average particle size of 10 ?m or less, and a total weight of the solid lubricant is 0.1 times or more and two times or less a total weight of the binder resin.

Abstract: A solid lubricating coating film capable of imparting favorable lubricity and corrosion resistance to a connection for oil country tubular goods. Two or more solid lubricants are dispersed in a binder resin. Graphite is contained in an amount of 50% or more and 90% or less of a total weight of the solid lubricants, and the graphite has a scaly shape and an average particle diameter of 10.0 ?m or less. A solid lubricant made of one or more materials selected from BN, mica, talc, MCA, MoS2, PTFE, PFA, and FEP is further contained as other solid lubricants of the two or more types of solid lubricants. The binder resin contains a PEEK resin having an average particle diameter of 20 ?m or less as a main component, and the PEEK resin is contained in an amount of 70% or more of a total weight of the binder resin.

Abstract: An agent for forming a solid lubricating coating film on a tightening surface of a thread portion, in which a solid lubricant is dispersed in a binder resin as a matrix component, a main component of the solid lubricant is melamine cyanurate, and an average particle diameter of the melamine cyanurate is 0.1 ?m or more and 10.0 ?m or less, the binder resin contains an alkyd resin and nitrocellulose, and the alkyd resin and nitrocellulose are contained in an amount of 85 wt % or more of the total binder resin component weight, and a total weight of the solid lubricant is 10 parts by weight or more and 100 parts by weight or less based on 100 parts by weight of a total weight of the binder resin.

Abstract: A solid lubricating coating film is used to realize galling resistance equal to or higher than a method using a dope compound regarding lubrication characteristics during make-up/break-out of oil country tubular goods. A threaded joint for oil country tubular goods includes a box having a thread and a pin having a male thread. A lubricating coating film including a solid lubricating coating film forms on a tightening surface of a thread portion of at least one component of the box and pin, the solid lubricating coating film is formed by dispersing a solid lubricant in a binder resin, 90 wt % or more of the binder resin is a polyamideimide resin, an average molecular weight of the polyamideimide resin is 20,000 or more and 40,000 or less, 80 wt % or more of the solid lubricant is polytetrafluoroethylene (PTFE), and an average molecular weight of the PTFE is 30,000 or less.

Abstract: A bearing apparatus includes a rotating member, a fixed member opposing the rotating member and an ink-like resin material. Opposing surfaces of the rotating member and the fixed member form a bearing part and the ink-like resin material is applied to at least one of the opposing surfaces by transfer printing.
