WHAT A THIN SECTION Bearings are IS, how do you cut down costs?
Thin section ball bearings were developed for applications where space constraints are most important. As the name suggests, the difference between the inner diameter and outer diameter of the ring is minimized or thinned. Of course, you pay for the cost by sacrificing the load capacity. However, these bearings can still handle relatively light radial thrust or composite loads.
6700 Series - Metric Dimensional Series for extremely limited space applications and extremely light loads
6800 Series - Metric Dimensional Series for limited space applications and light loads
