A slide bush (13) made of synthetic resin with high temperature resistance may be combined in a stentering frame chain with a roller (11) made of a synthetic resin with high temperature resistance of the same class in spite of unfavourable mutual friction coefficients. For that purpose, the two parts (13,11) are secured to each other against rotation and_a positive engagement with radial play (14) is provided between the slide bush (13) and the roller (11). |
