Axial ball recirculation, low-friction guidance:

Ball bearings from norelem
Linear ball bearings are used when a mechanical engineering component needs to be guided along a cylindrical shaft using linear motion and with low friction. In contrast to conventional ball bearings, the shaft guides have axial ball recirculation.

norelem offers its customers ball bearing bushes with steel and plastic housings and raceway segments made from hardened steel. These guide the ball sets within the system and ensure unlimited travel at low guidance. The linear bearings are therefore important components for the mechanical engineering and fixture construction industries and are used in applications including automatic production machines, machine tools and rolling stock as well as in the food and medical technology sectors.

norelem offers ISO series 3 ball bearing bushes (in accordance with DIN 10285) with internal diameters of 12 mm, 16 mm, 20 mm, 25 mm and 30 mm as well as with load ratings of 420 N to 8300 N (dynamic) and 714 N to 9100 N (static). These are available as both open and closed designs. Open versions are primarily used in conjunction with shaft supports under particularly high loads.

Linear bearings perfectly matched to the area of application

Linear ball bearings are as versatile as their applications and, depending on the temperature range or load, certain ball bearing bushes are more suitable for the task at hand than others. For example, at particularly high temperatures (e.g. in ovens), linear ball bearings with steel cages are needed, whereas under particularly high loads and especially when combined with shaft supports, linear ball bearings with high load ratings are what are required. Self-aligning ball bearings, on the other hand, are what are called for in applications requiring tolerance compensation. We would be happy to provide you with comprehensive advice regarding the ideal ball bearings for your projects as well as on the following products with which they can be combined:
