Grease Equipment

Grease Equipment

Grease guns and lubrication equipment are the tools through which grease is delivered from its storage container to the bearing, fitting, or lubrication point. The grease gun generates the pressure required to open the check valve in the grease nipple and inject grease into the bearing cavity against the back-pressure of the existing grease charge. A quality grease gun, correctly operated with the right coupler and a consistent lubrication schedule, is the foundation of an effective bearing maintenance program. AIMS Industrial supplies grease guns, lubrication accessories, and bulk grease handling equipment for industrial and commercial maintenance operations.

Grease Gun Types

• Lever (pistol grip) grease guns: The standard manual grease gun. Each lever stroke delivers a measured dose of grease — typically 1.5–2g per stroke depending on the gun design. The measured dose allows consistent lubrication quantities to be applied per fitting. Quality lever guns deliver grease at 300–500 bar, sufficient to open most industrial grease nipples even when the grease is cold or the bearing cavity is fully packed.
• Inline (barrel) grease guns: Two-hand operation with a plunger-style handle. Provides higher leverage for frozen or blocked nipples. Less common for routine lubrication work due to the less ergonomic operation compared to pistol grip guns.
• Battery-powered grease guns: Motorised grease gun that delivers grease continuously at a controlled flow rate from a trigger action. Reduces operator fatigue in high-point-count lubrication programs, and eliminates the variable pressure of hand-operated guns for more consistent lubrication dosing.

Grease Cartridges and Bulk Handling

Standard 400g grease cartridges (the most common size in Australian workshops) fit the majority of lever and battery grease guns. Bulk filling from drums is more economical for high-volume lubrication programs — a suction gun filler or drum pump fills the gun directly from a bulk drum.

Maintaining Your Grease Equipment

Grease gun reliability depends on regular maintenance of the equipment itself. Purge and clean guns periodically to remove old, oxidised grease from the barrel and pump mechanism — contaminated grease introduced to bearings can cause premature failure. Inspect flexible hoses and rigid extensions for cracking, kinking, or swaged-end damage that could cause failure under pumping pressure. Check coupler jaws for wear — worn couplers allow grease to bypass the nipple rather than entering the bearing housing. Battery-powered grease guns should have their battery contacts cleaned and checked seasonally, and batteries stored at partial charge if the gun will be inactive for extended periods.
