The ball retained type is newly released !
CAT-57110C
Linear Way U
The safety-assured structure
[
ball retained type
]
is newly released.
When the slide unit is separated from the track rail, the steel balls are held in place without falling out.
So, this type is very easy to handle.
The stainless steel made miniature type series
with a rail width of 25 mm and 30 mm is newly released.
Adopting the U-shaped track rail
increases the rigidity greatly.
New concept

Linear Way U has been further evolved.
The U-shaped track rail of Linear Way U
can be used as a structural member;
it is a new design concept !
Rigidity of track rail under moment and torsion is very much
increased by adopting the U-shaped design. The track rails
can, therefore, be mounted on machines and equipment as
structural members, either in a cantilever position or
supported at both ends, so they can be combined and
assembled freely.
Low cross sectional height
and compact shape!
Slide units and track rails have compact shapes, with cross
sectional height made as low as possible. As the result,
design of drive mechanisms and other peripheral divices
can be made more freely, and machine size and weight can
be reduced.
High precision and rigidity!
Additional work on track rail is possible!
Large diameter steel balls in the slide unit are arranged in
two rows, and makes contact with the raceways at four
points. Stable high precision and rigidity are thus obtained
even under fluctuating or complex load.
Additional work can be made on track rails, so that drive
mechanisms and other peripheral devices can be fixed
directly to the track rails.
(*Note that additional work cannot be made near the
raceways of track rail. For details, please consult .)
Wide variations of assembly configurations contribute to increase design flexibility!

Linear Way U
Linear Way U is a linear motion rolling guide
featuring a track rail with a U-shaped cross section.
Raceways are provided on the inside surface of the
track rail, and a slide unit mounted inside the track rail
travels along the raceways.
The U-shaped track rail of Linear Way U has much
higher rigidity as compared with the track rail with a
rectangular cross section, especially under moment
and torsion. Therefore, in addition to the conventional
way of fastening a track rail on a mounting base, it
can be used by itself as a structural member of
machines and equipment, in a cantilever position or
being supported at both ends.
Number of slide units, preload, accuracy, etc. can also
be specified in the same way as in other Linear Way
series, so that the optimal specification can be
selected meeting the requirements in the application.
