(1) High self-aligning capability (rolling direction)
Same as the DF combination in angular contact bearings,
self-aligning capability is high because the cross point of
the contact lines of balls and grooves comes inside,
reducing moment rigidity.
This increases the capacity to absorb the error of
installation.
(2) High load carrying capacity to vertical
direction
The contact angle is set at 50 degrees, increasing load
carrying capacity as well as rigidity in vertical direction.
(3) High resistance against impact load
The bottom ball groove is formed in gothic-arch and the
center of the top and bottom grooves are offset as shown
in Fig.I-5•2. The vertical load is generally carried by the
top rows, at where balls are contacting at two points.
Because of this design, the bottom rows will carry load
when a large impact load is applied vertically as shown in
Fig.I-5•3. This assures high resistance to the impact load.
(4) Highly accurate as shown in Fig.
I-5.4, fixing the master rollers is easy thanks to the
gothic-arch groove. This makes easy and accurate
measuring of ball grooves.
(5) Easy to handle, and designed with safety in
mind.
Balls are retained in the retainer, therefore they do not
fall out when the ball slider is withdrawn from the rail.
(6) Abundant models and sizes
Each series has various models of ball slides, rendering
the linear guide available for numerous uses.
(7) Interchangeable series is available (prompt
delivery)
The series enables random matching of rails and ball
slides (interchangeability) for prompt delivery.
