REQUIREMENTS

SELECTION

1.) DETERMINE INPUT TORQUE AND

RPM REQUIRED

To select the Slide-Rite®, Slide-Rite®CR Gearbox, or Float-A-Shaft gearbox required for your application, you must determine the input torque and RPM required for your application. The maximum RPM rating for the Float-A-Shaft is 500 RPM, for the Slide-Rite® and the Slide-Rite®CR Gearbox it's 1200 RPM.

2.) NEED A GEAR RATIO OTHER THAN 1:1?

When utilizing the Float-A-Shaft ratioed units, the highest RPM shaft speed on either the input or the output shaft should not exceed 500 RPM. For the Slide-Rite ratioed units, the shaft speed (input or output) should not exceed 1200 RPM.

3.) REFER TO THE CATALOG PAGE FOR THE RATIO YOU HAVE SELECTED

Find your input torque in inch-pounds for the selected gearbox unit on the graph and intersect it with the RPM of the input shaft. In general, gearbox capacity increases as listed below:

1.) Float-A-Shaft: Compact: Low Torque Journal Bearings 2.) Float-A-Shaft: Compact: High Torque Roller Bearings 3.) Slide-Rite CR: Compact

4.) Float-A-Shaft: Standard: Low Torque Journal Bearings 5.) Slide-Rite: Compact 6.) Slide-Rite CR: Standard

7.) Float-A-Shaft: Standard: High Torque Roller Bearings 8.) Slide-Rite: Standard

For ratios other than 1:1 refer to the performance graph for that Float-A-Shaft gearbox. When torque vs RPM intersects below the 300°F curve, you have selected a gearbox suitable for your application.

If your torque vs RPM intersection point is above the 300°F curve, then you do not have a proper application for that gearbox. Your options are to reduce either your input torque or RPM to get under the 300°F curve or try a gearbox with greater capacity.

4.) SELECT PROPER BORE SIZE

After gearbox series selection, choose the bore size that suits your shaft requirements. (NOTE: Float-A-Shaft high torque roller bearing models and Slide-Rite 1:1 ratio models are available in metric sizes also.)

5.) DETERMINE YOUR OUTPUT TORQUE
