In order to achieve the result, in the case of a stentering chain with deflection about axes that stand vertical to the surface of the web of material, that the chain can be guided through the deflection zone with tilting of the linking pins, without damage to the pin bearings, the deflection pins are configured to be crowned elements. The deflection bolt bearings are shaped to correspond to the crowning of the pins.
