A pulley (100) for a passenger conveyor system is provided. The pulley comprises: a pulley axis (150) about which the pulley rotates; a cylindrical sleeve (105); and a bearing (120a, 120b) centered on the pulley axis and arranged to rotate about the pulley axis. The cylindrical sleeve comprises: an outer surface (110) comprising a groove (155) arranged to receive the band; and an inner surface (115) defining a cylindrical cavity (122) centered on the pulley axis. The bearing comprises an outer race (125a), an inner race (130a) and one or more rolling elements (135a) therebetween wherein the outer race comprises a protrusion (140) arranged to retain the bearing within the cylindrical cavity due to engagement between the protrusion and the inner surface of the cylindrical sleeve.
