Lubricating Greases

Greases reduce friction and wear in mechanical parts working in contact, such as bearings, joints and gears, and protect against rust. Grease guns deliver the grease to the right point, even in hard-to-reach areas. This collection includes both the greases and the tools for applying them.

Each type of grease has a different use. Lithium grease is a multipurpose grease for bearings and common mechanical parts. PTFE grease is suited to reducing friction in special conditions, and silicone is suited to seals and rubber parts. Copper grease is used where there are high temperatures or a risk of thread seizure. Choose based on the parts to lubricate and the manufacturer's instructions.

Clean the lubrication point of dirt and old grease before starting, otherwise dirt enters the bearing. Apply grease with the lever gun using regular strokes, until you see a slight bleed of fresh grease from the edge of the bearing or joint. Stop when grease comes out of the correct point.

The air grease gun uses compressed air pressure to push the grease, so it needs a compressor. The battery one has an integrated electric pump, more practical where air is not available. The lever gun is manual and needs no power. Choose based on the availability of compressed air, the volume of work and the frequency of lubrication.

Oilers with a flexible spout reach tight, difficult points, such as hinges and mechanisms with light movement. Metal oilers are more robust, while plastic ones are lighter and practical for occasional work. Use a thin oil and lubricate with a few drops, as excess attracts dust and dirt.

Oil syringes, including 500 ml ones with a flexible hose, are used to dose lubricant precisely where a container cannot reach. Reinforced flexible hoses and nylon hoses connect the pump or syringe to the point to be lubricated. Choose a hose with a diameter and pressure rating compatible with the fitting and the type of oil to be dispensed.

Close grease containers tightly to prevent dust and moisture from entering, and store them in a dry place at moderate temperatures. Keep grease guns clean after use, removing residue from the pump and tube, and store them in a box or sealed container. Check the expiry date shown on the packaging.

A multipurpose grease covers many common applications, but does not replace a specific grease where the manufacturer requires one. For high-temperature bearings, rubber parts or electrical components, check compatibility on the technical data sheet. Do not mix greases with different base oils without checking, as they may lose consistency.
