Guiding Rollers
The “Rotating” slides are mounted with two or three guiding
V-rollers (depending if slide has 3 or 5 rollers in total), which
are aligned against the same lower raceway for max. radial
load capacity. While one or two (depending if slide has
three or fi ve rollers in total) floating P rollers are mounted
against the upper raceway. This configuration allows the A
slide a minor rotation, around the contact points of the lower
raceway. This compensates for axial misalignment, while
maintaining its original preload and same straight,
precision motion.

Floating Rollers
The “Floating” slides contain only floating rollers, three or
fi ve in total. The contact areas with the raceways only provide
for radial load and Mz capacities, thus allowing for axial
movement and a simultaneous slight rotation of the slide to
offer axial and longitidinal compensation, while maintaining
original preload and same precise and smooth straightline
movement.
