A roller bearing and newel guide assembly () for a newel () in an escalator () has a newel guide (), a roller chain (), and a spring () connected between the roller chain () and the newel guide () to provide tension to the roller chain (). The roller chain () comprises a series of interlinked chain units (). Each chain unit () includes a frame (), at least one roller bearing (), and a pin () for connecting the roller bearing () to the frame (). Each chain unit () has a female connector () and a male connector (), which allow each chain unit () to connect to an adjacent chain unit () to form the roller chain ().

A connection between step flange coversand passenger conveyor framesis adjustable to vary the position of a step flange cover relativeto moving tread platesor a moving skirtin at least two directions. The adjustable connectionpermits the step flange coverto be precisely positioned with respect to the tread platesor the skirtwithout the necessity of using crude adjustment techniques, such as, for example, using shims.

A balustrade assembly includes a decking panel and a skirt panel that are attached to one another and to a balustrade support structure without fasteners. A positioning device included in the balustrade assembly varies the position of the skirt panel relative to moving steps in two directions by pushing against stationary components that are a part of or otherwise connected to a frame of a passenger conveyor. A balustrade support employed in the assembly reduces material and manufacturing costs and is adjustable to vary the height of a balustrade panel and handrails in a passenger conveyor.
