The slides do not have a device to protect against particles.
As with any ball bearings devices, telescopic slides and linear guides are very sensitive to projections of particles in the raceways. The balls bearing will be stopped by the obstable and sliding will be stopped.
We don’t provide standard protection device against projections.Each case must be studied specifically. This should be considered at the design stage.
On some rails, we can provide an optional wiper.
