P60 Gearboxes Replaced by P61
  • P60 Gearboxes have been discontinued and replaced by the new P61 series.
  • P61 gearboxes are drop-in replcemetns for the P60s - all external dimensions and mounting are identical.
  • P61 Front Blocks, Shafts, and Output Carrier plates have been redesigned to provide more than a 25% torque capacity increase

    Standard P60 Gearbox configured to mount 1 motor with either a 3.2mm or 5mm shaft and either a 13mm, 15mm or 17.5mm boss. Motors with this configuration include RS-540, RS-545, RS-550, RS-555, RS-775, and RS-775 motors. Many hobby motors and cordless drill motors are this size.

    Gearbox will be delivered assembled and tested; however, it will need to be disassembled to grease and mount the motor prior to use. No special tools are required, typically only an allen wrench. A small arbor press or bench vise is useful for pushing the pinion onto the motor shaft.

    Prior to use the gearbox must be greased, grease IS NOT INCLUDED and must be purchased separately. We recommend Mobil XHP 222 Special grease; however, most lithium based ball bearing grease can be used. We do not sell grease separately, it can be readily purchased from most local auto parts stores or online suppliers such as MSC, Grainger, and McMaster among others. Custom gearboxes can be supplied greased.

    Standard Gearbox includes one mounting kit. Mounting kit contains everything required to mount 1 motor of the appropriate size including pinion, screws, and lock washers to attach the motor to the gearbox. (Mounting kit not included by default with custom gearboxes, it is an option.)

    Mounting a large load to the end of an unsupported shaft may damage the gearbox. The shafts on these gearboxes are supported by two ball bearings making them fairly rugged; however, we do not recommend them to be used with large overhung loads. We recommend using a design that supports the end of the shaft. If it is not possible to support the end of the shaft, we recommend mounting the load as close to the face of the gearmotor as possible and cutting the shaft to length. Our 1.5in square, 1/2in shaft bearing block provides a simple and effective way to support the shaft.

    We recommend maximum torque not exceed 35 ft-lb for all P60 Series Gearboxes. It is possible to mount motors that will exceed this in higher gear reductions. Higher reduction gearboxes should be utilized primarily for speed reduction. Designs utilizing a P60 gearbox / motor combination that will exceed 35 ft-lb should include a method of limiting torque to prevent damage to the gearbox.
