iSML055-08503-MADC may be considered as a candidate replacement — subject to engineering review. The incumbent application and this product's published specifications must be reviewed before selection.
Send the application, quantity and target date. We will check fit and availability.
We check the load, motion profile, gearing, feedback and brake before selecting the iSML055-08503-MADC.
An earlier working label said iSML-6.5, but the exact product on file is the 5.5-inch iSML055-08503-MADC
This page therefore uses the verified 5.5-inch model instead of inferring a 6.5-inch order code
Vehicle payload is not stated as a stand-alone value and remains subject to engineering review
A line-by-line BOM review checks the whole list against the application before it becomes an order.
