Battery-Operated Grease Gun

OilSafe Colour-Coded Battery-Operated Grease Guns offer the same great benefits as OilSafe manual grease guns with battery-operated efficient performance. One full battery charge (1 hour) provides power to dispense up to 6 grease cartridges in free flow conditions. Battery-Operated Grease Guns are the ideal choice to lubricate large bearings or manual centralised systems (used to lubricate multiple bearings from a single lubrication point.)

Oil Safe Battery-Operated Grease Guns are available with clear or steel body tubes in 10 standard OilSafe colours. (Clear Body Tubes with colour identification enable accurate identification of a lubricant by providing visibility of the installed cartridge or the grease level if bulk filled. Steel Body Tubes offer durable protection in a colour-coded tube for easy identification.)

  • No air source or airline needed
  • Applies grease without manual pumping
  • Pumps higher volume of grease
  • Estimated to be 50% faster than manual grease guns
  • Convenient for large bearings when up to hundereds of pumps are required per bearing every few days.

Ball bearings

Small and large ball bearings

The amount of grease required by a bearing is based on the bearing size.

Using three ball bearings to demonstrate this and to show when an electric gun should be used.

OilSafe colour-coded battery-operated grease guns are the obvious grease gun of choice to lubricate large bearings or manual centralised systems use to lubricate multiple bearings from a single lubrication point.

Modern electric grease guns generally use rechargeable batteries eliminating the need for power cords or, in the case of pneumatic guns, airlines adding convenience and versatility to the relubrication function. Rechargeable electric grease guns can produce up to 10,000 psi of pressure and deliver high volumes of grease quickly making them the grease gun of choice for those bearings that require more than several pumps from a manual gun. In addition to bearings requiring a high volume of grease, the rechargeable electric grease gun meets the challenges of pumping grease long distances to remote bearings or those located in dangerous areas. They can also provide the volume and pressure to lubricate several bearings on a centralized manifold distribution system.

  • OilSafe colour-coded battery-operated Grease Guns are the solution for manual lubrication of large bearings especially those that require frequent lubricant.
  • OilSafe colour-coded battery-operated Grease Guns give the user speed, efficiency, ease of operation, convenience and accuracy in the lubrication of large bearings.

  • How can the OilSafe grease gun be filled?
    All OilSafe grease guns can be filled with grease cartridges, bulk filled from a pail/drum or with the use of a grease pump.The written instructions packaged with each electrica grease gun illustrate the se filling options.
  • Does the quick coupling work on metric grease zerks?
    Yes. It automatically adjusts to grease zerk sizes, making connections quick and simple. When connected to a grease zerk, there is 6 points of engagement, so connections are secure and allow for hands free operation.
  • What to do when grease zerks get stuck or plugged?
    Occasionally a grease zerk could get plugged or prohibits the flow of grease from a grease gun. OilSafe has many grease accessories for unplugging grease zerks, installing them, colour identification options and various sized grease zerks available in our catalogue (pg 22).
