Planetary Gearbox Selection Guide & Buyer’s Checklist

Use this checklist alongside your Renold Australia representative to make sure your application data is complete before a planetary gearbox is quoted or sized. Ticking every box below will speed up selection and reduce the risk of an undersized or mismatched unit.

1. Actual output torque required (not just motor kW)
2. Peak / shock torque, in addition to steady-state running torque
3. Position of overhung and axial loads, if any, on the output shaft

Renold's Australian planetary range spans nominal output torques from 1,000 Nm to 2.5 million Nm.

1. Inline or right-angle (bevel) planetary arrangement
2. Flange, foot, or torque-arm mounting
3. Available envelope (space, weight, orientation)

Mobile applications often suit compact hub drives (approx. 7,000–90,000 Nm output torque).

1. Does the load need to be held statically (lifting, lowering, incline)?
2. Is an integrated static holding brake required?

Renold winch drives are available with static negative disc brakes, 5,000–400,000 Nm.

1. Required input and output speeds
2. Target reduction ratio

1. Ambient temperature range
2. Elevation
3. Dust, washdown, or corrosive / marine exposure

 

9.  Total Cost of Ownership

1. Compare on lifecycle cost, not just purchase price
2. Bearing life and expected service intervals
3. Local technical support and warranty terms

Once this checklist is complete, share it with Renold Australia to have your application sized against the appropriate planetary gearbox, hub drive, or winch drive range.
