Mounting orientation / load capacity / overhang / moment

Load capacity when mounted with upside down

We are considering using various stages (X axis, horizontal Z axis, tilt, rotation, goniometer)
attached to the ceiling.
How much does the load capacity deteriorate compared to the load capacity (horizontal placement)
described in the catalog?

The specifications for each product are based on installation on a flat surface.
As the load applied to the guide of stages changes, it is difficult to clearly define the load capacity
of the installation with upside down.

The followings are only for reference.

◆ It is possible to use if the load point is directly below the stage top (center).

* If load is applied to the overhanging position, the load capacity cannot even be estimated,
  and therefore we do not recommend the use.

Less than one third of the horizontal load capacity.
・ Various X axis stages
・ Horizontal Z-axis stage・・・B36 series(discontinued products)
・ Rotary stage(fitting type)・・・BRE series
・ Rotary stage(fitting type)・・・B43 series
・ Rotary stage(cross roller guide)・・・B44 / BS43 / B47 series

◆ Products that can not be used with upside down

・ Z axis stage・・・BSS(BSB)36 / B31 series
・ Horizontal Z-axis stage ・ ・ ・ B33 series(lever type) / B37-60
・ Rotary stage (ball bearing) ・・・ B48 series (discontinued products)
・ Tilt stage (discontinued product)
・ Z axis-mount・・・B34 seires
・ Lab jack・・・B35 series

Load capacity in vertical installation (Z axis)

We are considering using various stages (X axis, horizontal plane Z axis, tilt, rotation, goniometer)
attached to the bracket so as to use vertically (side vertical use).
How much does the load capacity deteriorate compared to the load capacity (horizontal placement)
described in the catalog?

■ In the case of the X-axis stage

If there is a model of Z axis stage with bracket attached to the stage, please refer to the load capacity
of that. model (Example: BSS16-40CZ → BSS36-40CU)
* The load capacity is the weight supported by the micrometer head (feed screw).

■ Other products

The specifications for each product are based on installation on a flat surface.
Because the load applied to the stage guide changes, the load capacity of the installation with the side
perpendicular cannot be clearly defined.

The following is only for reference.

◆ It can be used if the load point is near the center of the top of the stage.

* If load is applied to the overhanging position, the standard load capacity can not be estimated,
   therefore we do not recommend the use.

Less than one third of horizontal placement
・ Horizontal Z-axis stage (wedge) ・ ・ ・ B36 series (discontinued product)
・ Rotary stage (cross roller bearing) ・ ・ ・ B44 / B47 / BS43 series
・ Various gonio stages

◆ Use in side vertical not recommended

・ B15-150 series
・Horizontal Z-axis stage・・・B38 series（discontinued product)
・ Rotary stage (fitting type) ・ ・ ・ BRE series
・ Rotary stage (ball bearing) ・・・ B48 series (discontinued products)
・ Tilt stage (discontinued product)
・ Z axis-mount・・・B34 seires
・ Lab jack・・・B35 series

Load capacity when mounted on a wall in the direction to move left and right

We are considering using various stages (X axis, horizontal Z axis, tilt, rotation, gonio) attached to the
bracket so that the moving direction of the stage is horizontal (side horizontal use).
How much does the load capacity deteriorate compared to the load capacity (horizontal placement)
described in the catalog?

The specifications for each product are based on installation on a flat surface.
Because the load applied to the stage guide changes, the load capacity of horizontal installation cannot
be clearly defined.

The following is only for reference.

◆ It can be used if the load point is near the center of the top of the stage.

* If load is applied to the overhanging position, the standard load capacity can not be estimated,
   therefore we do not recommend.

Less than one third of horizontal placement
・X axis stage
・ Horizontal Z-axis stage (lever type) ・ ・ ・ B33 series
・ Horizontal Z-axis stage (wedge) ・ ・ ・ B36 series (discontinued product)
・ Rotary stage (cross roller bearing) ・ ・ ・ B44 / B47 / BS43 series
・ Various gonio stages

◆ Use in side horizontal not recommended

・Horizontal Z-axis stage・・・B38 series（discontinued product)
・ Rotary stage (fitting type) ・ ・ ・ BRE series
・ Rotary stage (ball bearing) ・・・B48 series (discontinued products)

Moment rigidity of Dovetail stage

The moment rigidity of Dovetail stage is not on the catalog spec. Why are they not specified?

The dovetail stage has a gap on the sliding surface.
There is individual difference in the size of the gap, and the difference in inclination when a moment
is given also increases.
Therefore, the moment rigidity is not specified.

If there is severe slope due to the moment, please select linear ball guide or cross roller guide products
which the moment rigidity value is specified.

I would like to use the rack rail type dovetail stage BDLXR with Z axis

Will there be any problem in using the rack rail type Dovetail stage BDLXR / BDLXB on vertical (Z-Axis)
such as in the camera focus.

In the case of a rack rail, there is a possibility that the table may come off because there is no stopper.
So, we do not recommend using it on the Z axis.

Please consider to take measures such as providing a stopper externally, or to use the B05 / B06 series
which has a built-in stopper.
