Recirculating Ball Bearing Guides
Recirculating
Ball Bearing Units
General design
mk recirculating ball bearing units consist of a track
and the guide carriage.
The roller carriage for the recirculating ball bearing
unit is made from hardened and ground steel.
Closed channels with plastic recirculation mechanisms
recirculate the four rows of ball bearings.
The roller carriage can be slid directly from the
guard rail onto the track.
The recirculating ball bearing units can carry loads
from any direction and have very rigid, heavy-duty
linear guides.
The standard mk guide carriages are lightly pre-
tensioned, making them suitable for most common
applications. If multiple carriages are arranged on
a rail or in parallel, then we recommend using carriages
with no pre-tension and little play to provide
better misalignment compensation and ease of
movement.
For products with high rigidity or fluctuating loads,
we recommend carriages with strong pre-tension
and precise, rigid contact surfaces. mk can supply
these versions on request.
The specified maximum load specifications already
take into account a static safety factor of s0 = 5 in
relation to plastic deformation on the roller contact,
and s0 = 2 for screw connections with 8.8 screws. Sample order for a guide
