Can't find what you need?

Engineering applications are not a one-size-fits-all proposition. We can customize nearly everything we sell, from modifying housings and mechanical interfaces to fine-tuning performance parameters. Interested in custom assemblies?




It’s easy to get preoccupied with motors, drives, controllers, and gearing. Without proper hardware, however, even the best design will not perform properly. We offer a comprehensive selection of hardware components designed to support machine function and streamline procurement.

Specialty Fasteners

Specialty fastenersIt’s easy to focus on the motion-control and automation aspects of a system, but if it won’t hold together, it can’t get the job done. We carry a wide array of specialty fasteners, including clean-room and vacuum specific designs, odd sizes, special materials, ultra compact, etc. Our experienced sales engineers will work with you to find the optimum hardware for your application, whether it involves temperature extremes, shock and vibration, size constraints, and more. Bring us your most challenging fastener needs and we will find a solution.


Lock Nuts

Lock NutLock nuts are designed to hold components in place even in the face of extensive vibration. These fasteners vary from a simple lock nut with a tanged washer to a lock nut incorporating mechanical features that prevent the nut from turning unless it is manually released.

Components like motors, controllers, and gearboxes can be very expensive. All too frequently, design teams seek to save money on fasteners like lock nuts, which they consider to be commodity items. That can be a penny-wise and pound-foolish decision. Depending on the manufacturer, a two dollar lock nut with high face run out could cause the failure of a $100 bearing. At Motion Systems, we have learned from experience that it is essential to use quality lock nuts.

The choice of lock nut makes all the difference in the performance and lifetime of a bearing system. Our lock nuts feature very highly controlled face run out, which is an essential characteristic to preserve bearing performance. We can supply self-locking locknuts ranging in size from 10 mm up to very large lock nuts for heavy-duty industrial applications. Choose from standard and high-precision designs. Thread classes include standard threads, fine threads, or metric threading.
