Tom from SWISCO responded:

Your roller assembly has been discontinued, the closest roller assembly we have is #81-162

The nylon wheel is 1-1/2", the housing height is 1-1/4", the housing width is 3/4", and the dimples bring it out to 7/8". 

Please compare these dimensions to your part and see if these can work for you.
