Profile Rail – SBI Recirculating Ball Bearing Guide
Recirculating Ball Bearing Guide with X-Arrangement of Raceways
SBI recirculating ball bearing guides have four closely spaced rows of balls. Due to the force distribution, this arrangement is often referred to as an X-arrangement. These guides are somewhat more elastic than standard O-arrangement guides, allowing them to better accommodate larger misalignments without jamming. For this reason, they are frequently used in handling technology.

Characteristics
SBI linear guides feature four rows of balls arranged in an X-arrangement, which makes the system significantly more flexible with respect to assembly inaccuracies.
However, this increased flexibility comes at the expense of rigidity.
Recirculating ball bearing guides with an O-arrangement are considerably stiffer.
Applications
SBI recirculating ball bearing guides are particularly well-suited for handling applications due to their slightly softer design. With the same preload, larger deviations on the mounting surfaces can be accommodated.
When used in machine tools for machining, a higher preload class must be selected compared to linear guides with an O-arrangement to achieve a comparable level of rigidity. Note that this higher preload can negatively affect service life.
