A method for producing a sliding coupling, which comprises injecting a casting material comprising the following components (A) and (B) into a clearance between a bearing and a shaft fitted in and rotatably or reciprocatively supported by the bearing, followed by polymerization and curing to form a resin lining on the surface of the shaft or the bearing: (A) a .omega.-lactam liquid containing a polymerization catalyst of an alkali metal or alkaline earth metal compound; and (B) a .omega.-lactam liquid containing at least one polymerization initiator selected from the group consisting of a polyoxyalkylene, an oxyalkylene copolymer, a polyalkadiene, an alkadiene copolymer, a polyalkene and an alkene copolymer, each of which has at least two terminal groups selected from the group consisting of lactam terminal groups of the following formulae: Image , Image , and Image , wherein Q is a lactam residue having a C3-C11 alkylene group, said lactam residue being bonded to C, P or S via its nitrogen atom; A is an aliphatic or aromatic hydrocarbon group, or a hydrocarbon group having an ether linkage; m is 0 or 1; when m is 0, n is 0 or 1, and p is 1; when m is 1, n is within a range of from 1 to 3, and p=n; R1 is an alkyl group, an aralkyl group, an alkoxy group, an aryloxy group, a halogen atom or an aralkyloxy group; and R2 is a hydrogen atom or an alkyl group; or at least one polymerization initiator selected from the group consisting of lactam initiators of the following formulae; Image , Image , and Image wherein Z is a polypropylene oxide polyol, t is at least 1, and Q, A, m, n and p are as defined above.
