Miniature Linear Bearings Offer Maximum Performance

In the semiconductor, medical, surgical, robotics and precision machinery industries, components must sometimes be sized to the smallest dimensions possible to meet demanding performance criteria. When bearing sizes range from 1 to 25mm, load capacity and maintenance can become more of an issue than in larger units.

In a new white paper, IKO addresses some of the most important considerations you should keep in mind when specifying miniature bearings.

Linear Guides For The Next Generation Of Medical Machines

Not too long ago, the motion systems used in medical and lab automation equipment had technical requirements that were easy to satisfy. These lightly loaded applications generally required simple point-to-point moves with low to moderate positioning accuracy requirements.

With the exception of surgical robots and some diagnostic systems, many medical machines still have modest positioning accuracy requirements, at least compared to applications such as semiconductor and electronics assembly. Yet the motion axes in medical machines do have to run smoothly and quietly, sometimes at high speeds.

Maintenance Free Linear Guides (C-Lube)

Walk through any plant that uses linear motion systems, and you can often see maintenance workers, grease gun in hand, applying lubrication to linear guides. And why shouldn’t they. Under-lubricated guides can wear excessively, which leads to performance problems and premature failure.

These labor-intensive lubrication practices, however, do not come cheap. We estimate that manual lubrication can cost upwards of $500 per grease fitting, per year when you consider the cost of the lubricant itself and the wages of the guy with the grease gun. And that figure doesn’t begin to capture the total cost of manual lubrication when you consider that many grease fittings are difficult to access and service without triggering some downtime.

Reliable Linear Motion For Packaging Machines

In the productivity-driven packaging industry, there are many possible sources of downtime. You can eliminate many of them by selecting failure-resistant linear motion components.

These robust guides and positioning tables have design features that prevent premature failure due to poor lubrication practices or contamination. At the same time, these linear motion components still have to meet the necessary accuracy, precision and load requirements—all of which are on the upswing in packaging applications.
