Linear bearings are bearing elements for translation type motion. As in the case of rotary bearings, a distinction is drawn as to whether the forces occurring are transmitted by means of rolling or sliding elements.

The requirements placed on linear components are as varied as the applications in which they are used. In transport and feed systems, it is mainly speed and accuracy that are required while, in measuring machines for example, the emphasis is more on precision and rigidity. In order to find the right linear guidance system for the specific task, both a sophisticated product range and detailed consultation are important. INA offers both: a wide range of linear products, combined with expert service. Furthermore, a range of accessories precisely matched to applications allow even greater optimisation of the comprehensive standard versions of guidance systems.

Each linear design has particular characteristics that make it especially suitable for particular bearing arrangements. Generally applicable rules for selecting the type of guidance system can only be formulated up to a point, since more and more factors must be taken into consideration and weighed up against each other. Apart from load, acceleration, speed and stroke, factors including temperature, lubrication, vibration, mounting, maintenance etc. must be taken into consideration.
