Note
Linear ball bearing consisting of a guide rail and a race which runs within the ball cage in the guide rail. The preferred installation position is vertical.
The specified load capacities refer to the maximum value at 50,000 cycles.

The internal stops limit the cage. Provide external stops for a loaded system.

The head height of the mounting screws should not exceed a height of 0.9 mm, otherwise there is a risk of collision with other linear ball bearing parts.

Recommended screws: M 2.5.
Maximum screw length = panel thickness + 2.2 mm.
Temperature range
5 °C to 35 °C
Drawing reference
1) the rails with length 70 mm have no hole here
