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 42 mm, 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. They include:
- Zero maintenance lubrication. In moving systems, proper lubrication is key. This is especially true in smaller components that have harder to reach areas. IKO solves this problem in its line of miniature guides by using C-Lube, a built-in lubricating element that provides you with long lasting, maintenance free operation through capillary action.
- Multiples sizes and load capacities. Sizes and load ratings in miniature linear bearings are often limited. In IKO’s standard miniature line, however, track widths range from 1 to 42 mm. At the same time, they feature dynamic load ratings of more than 16,700 N and moment load ratings higher than 320 N●m in the roll axis.
- High performance materials and coatings. When material choices for miniature bearings are limited, engineers tend to either over-specify or under-specify the components that make up the larger system. IKO’s miniature guides are available in various materials and coatings, allowing them to be used in demanding environments facing humidity, moisture or thermal extremes.
- Interchangeable, flexible components. Instead of having to purchase a completely new setup after just one part fails, look for linear guides that feature interchangeable parts. IKO offers slide units and track rails as separate pieces, which means you can simply swap out the failed unit for a new one.
