Selection Procedure
1. Determine the output speed and torque required for your application. The maximum recommended output
speed is 3000 rpm for 1:1 units, and 1500 rpm for 2:1 units. 2:1 units are NOT recommended for use as
speed increasers.
2. Select an application service factor from the chart to the right. Multiply your torque by the selected
service factor. If you are unsure of the factor to be used, please consult us.
3. Using the chart below, find your output speed on the left. If your speed is not shown, use the next highest
speed. Depending on the ratio you need (1:1 or 2:1), follow the chart across until you find a torque value
that is larger than your corrected torque value.
4. The Unit Size you need will be at the top of that column. There are 5 sizes available. At the bottom of the
column is a list of the various models available under the selected size. Select the model number, based
on the gear ratio and the number of shafts you need (2 or 3). When ordering, use the model number you
selected, along with the ratio desired.
5. Check the applied radial & thrust loads on the unit compared with the loads in the chart at the bottom.
If the applied loads are larger than the chart values, a larger unit must be selected.
6. Refer back to pages 4 & 5 for dimensional information on the model you selected.

Selection Example
An application to connect a drive-shaft to a fan-shaft at a right-angle with a 1:1 ratio. Input & output connections with timing
belt pulleys at 1,000 rpm. Input power is 1 kW. Operating conditions are moderate shock, 12 hr/day.
1. Output speed is 1000 rpm. Operating torque = 9,550 x 1 kW / 1000 rpm = 9.55 Nm.
2. Service factor from chart (12 hours/day, moderate shock) - SF=1.3. Corrected torque = 9.55 x 1.3 = 12.42 Nm.
3. From ratings chart (output speed = 1000 rpm), unit torque = 27.1 Nm (> 12.42 Nm) - Size 3 1:1.
4. The model selected is: R3330M for two-way or R3350M for three-way.
5. The applied radial loads are calculated to be 33.6 kg on each shaft (< 45.4 kg), which is allowable.
6. On pages 7 & 8, the dimensions are checked to confirm available space for model selected.
OUTPUT SPEED (RPM)
* Unit ratings are: Output Torque in Nm and Output Power in kW.
