3.2.2 Mounting the Table Top
AFD92
The AFD90-3 is designed for mounting on a stationary fixture. It has four (4)
0.41”
(
10.5 mm) mounting holes spaced as shown in Figure 3. The
AFD90-3
Table Top
Mounting Bracket should not be modified without first consulting PushCorp, Inc. The
surface that the Mounting Bracket is mounted to must be flat to avoid distorting the
base.

3.3 Maximum Carriage Load Calculations
The Linear Rail bearings that support the
AFD92
Carriage have been selected to
provide optimal performance with respect to capacity, size, and low friction. To ensure
optimal performance it is very important not to overload these bearings. The following
diagrams and associated equations are provided to check your application for excessive
loading.
It is important to note that these equations require the use of Metric units. The
necessary unit conversions are provided for your convenience. Insert your maximum
applied force and process equipment weight (W) and overhang distances (D) to
calculate an actual bearing load (L) that must be less than the maximum bearing load
shown on the right side of the equation. The life of the bearings is 100,000 meters of
linear motion, at the maximum allowable bearing load value. Exceeding this value (L)
will reduce the life, and operating at less than this value (L) will increase the life. It is
common to have combined weight and force loads on the Carriage. These situations
may require adding two or more of the scenarios shown below. If your application is not
similar to any of the designs listed here, or if you are unsure of your application, please
