SUBJECT: 5" Diameter Top Drive Shuttle Tractor Wheels
Dear MILNOR Dealer/Customer:
We have just changed the material specification on the 5 " diameter top drive shuttle tractor wheels, p/n 6OC507SB and 6OC507LB.
The original top drive shuttle tractor wheel was provided by both Continental and Dayco and were made of natural rubber compounds. Due to the successful application of molded urethane on dryer support rollers, we chose to change the shuttle wheels to molded urethane.
We now use bottom drives on most shuttles and COBUC (which uses a 9" diameter wheel simiIar to a dryer) but still see significant usage on the top drive shuttle tractor wheels as spare parts.
From this day forward, we will only ship urethane wheels under p/n 6OC507SB and 6OC507LB. Other roller/wheel applications are also subject to change to urethane in the near future. We will keep you posted.
If you have any concerns or questions about performance on these wheels, please contact me directly.
Please communicate this information to any customer inquiring about purchase of these tractor wheels.
Thank you for your continued confidence.
Best regards,
PELLERIN MILNOR CORPORATION
