From ROLLON Corporation
How do you know when a linear bearing has reached its
end of travel? When the carriage hits the wall. At least, that
is how the old engineering joke goes. But in reality, crashes
are no laughing matter.
Also known euphemistically as "hard stops," crashes occur
when an out-of-control pillow block slams into the bearing's
end stop or some other intermediate target. They most
often occur when a linear axis is started up for the fi rst
time. Even a single crash on that very fi rst stroke can ruin a
bearing, triggering expensive repair or replacement costs.
