It’s important to note that this process does not automatically translate to greater expense or increased production timeframes. In fact, the opposite is true, enabling
design innovations such as smaller overall size, simplified
design, and improved assembly. Using the right material,
achieving proper sizing, eliminating components, and including additional features sets the designer free to develop
the best medical device instead of settling for a less than
2. Smaller, More Compact
Many design engineers don’t realize the enormous and
negative impact a standard bearing can have on the size and
complexity of a device.
Custom bearings can be properly sized to fit the demands of an application. Dependent on load and speed of
the application, bearings can be designed with just the right
number of rolling elements, or using races that have unique
diameters or widths. That means a housing or mount can be
designed for the bearing that is smaller and less expensive. It
also means that an adapter does not need to be added to fit
a shaft or spindle to a standard bearing bore.
Custom bearings can be made from the appropriate materials that are lighter, non-magnetic, or resistant to contamination. Engineering grade plastics, non-magnetic metals, and
ceramics can be used so that the design is more focused on
the application and less on protection of the bearing.
Custom bearings can be made to fit the lifecycle of the
design. Not all applications need to perform millions of cycles,
spin at thousands of rpm, or last for decades of use. Particularly in disposable or limited-use applications, a bearing that
is designed to match the performance requirements of the
device can be much more cost effective.
3. Feature Rich
Standard bearings are just that — standard. The sole function
of the bearing is to reduce friction during movement. To
