Frequently asked questions
Can M+S orbital motors be used as drop-in replacements for other brands?▾
M+S orbital motors offer standard flange mounts per series along with parallel-key, splined, tapered, and wheel-mount shaft options. If you provide the displacement, flange, and shaft specifications of your currently installed motor, we can help select a compatible model.
Can I also purchase replacement parts such as seal kits?▾
Yes. We keep key replacement parts such as seal kits in stock, so maintenance can be handled without replacing the entire motor.
What are the lead times for stocked items?▾
M+S is one of our largest stocked brands, with roughly 300 items kept on hand at all times. In-stock items ship immediately; for non-stocked configurations, we will quote the order lead time separately.
