Elesa lubricants and greases for professional maintenance
Elesa lubricants and greases are intended for the maintenance of machinery, vehicles, tools, mechanisms and equipment subject to friction, humidity, pressure or continuous movement.
Proper lubrication helps reduce direct contact between surfaces, limit wear, protect against corrosion and extend component service life.
The range includes multipurpose greases, products for high loads, aerosol lubricants, oils, food-grade greases and solutions with different consistency grades.
Types of greases according to application
Not all mechanisms work under the same conditions. Load, speed, temperature, humidity and the greasing system determine which product is most suitable.
Multipurpose greases
Suitable for general maintenance operations on bearings, joints, shafts, chassis and mechanisms working within conditions compatible with their formulation.
Extreme pressure EP greases
They include additives intended to improve protection when surfaces work under high loads, impacts or significant mechanical stress.
Greases with molybdenum disulphide
Products with MoS₂ incorporate a solid lubricant that helps maintain a protective film in mechanisms subject to pressure, vibration or slow movements.
Greases for special applications
Specific formulations are available for high or low temperatures, humidity, corrosive environments, food machinery and automatic lubrication systems.
Lithium grease for general maintenance
Lithium grease is one of the most widely used solutions for general lubrication of machinery, bearings, chassis, joints and workshop equipment.
Its behaviour against water, oxidation and temperature variations depends on the specific formulation, additives and selected NLGI grade.
Common applications
- Ball and roller bearings.
- Joints and greasing points.
- Vehicle and machinery chassis.
- Agricultural and construction equipment.
- Workshop tools and mechanisms.
- General industrial maintenance.
Spray lubricants and technical oils
Aerosols and light oils make application easier in narrow points, precision mechanisms and components where a dense grease is not suitable.
- Chains and steel cables.
- Hinges, guides and joints.
- Locks and small mechanisms.
- Hard-to-reach points.
- Temporary protection against humidity and corrosion.
- Preventive maintenance of tools and equipment.
Before using an aerosol, check compatibility with plastics, elastomers, paints and surfaces close to the application point.
Lubricants for the food industry
In food, pharmaceutical or packaging installations, lubricants suitable for the environment and possible contact with food must be used.
NSF H1
Identifies lubricants suitable for applications where incidental contact with food may occur within the conditions intended for the product.
NSF H2
Corresponds to lubricants intended for areas where there is no possibility of contact with food.
Always check the specific certification, registration number and permitted application in the technical sheet of each reference.
NLGI consistency grades
The NLGI classification indicates the consistency of a grease, from semi-fluid products to firmer formulations.
- NLGI 000, 00 and 0: fluid greases used in certain gearboxes and centralised greasing systems.
- NLGI 1: soft consistency for specific applications and systems requiring good pumpability.
- NLGI 2: common grade in many general applications and bearings.
- NLGI 3: more consistent grease for applications requiring greater permanence at the lubrication point.
The appropriate grade will depend on equipment design, temperature, speed, load and application method.
Features to check
- Base oil: mineral, synthetic or another formulation.
- Thickener: lithium, lithium complex or another technology.
- NLGI grade: determines grease consistency.
- Working temperature: check the minimum and maximum limits.
- Dropping point: provides guidance on the thermal behaviour of the grease, but is not equivalent to continuous service temperature.
- EP additives: recommended for certain high loads.
- Water resistance: important outdoors and in humid environments.
- Anti-corrosion protection: helps preserve metal surfaces.
- Certifications: check NSF, DIN, ISO or other specifications when required.
How to choose a lubricant or grease
- Component: bearing, chain, gear, joint, cable or mechanism.
- Load: normal, high, with impacts or vibrations.
- Speed: fast and slow mechanisms may require different formulations.
- Temperature: check the actual operating range.
- Environment: humidity, water, dust, chemical agents or outdoor use.
- Application method: manual, grease gun, spray or centralised system.
- Frequency: occasional, periodic or continuous lubrication.
- Compatibility: check the existing lubricant before mixing products.
Do not mix greases without checking compatibility
Greases with different base oils, thickeners or additives may be incompatible and lose consistency, lubricating capacity or stability.
Before changing product, consult the technical documentation and clean the system when the manufacturer or application requires it.
Frequently asked questions about lubricants and greases
What is lubricating grease?
It is a semi-solid lubricant usually composed of a base oil, a thickener and different additives. Its consistency allows it to remain on the component for longer than a liquid oil.
Are lubricant and grease the same thing?
Lubricant is the general term. It includes oils, greases, aerosols and solid lubricants. Grease is a specific type of lubricant with semi-solid consistency.
What is the difference between lithium grease and molybdenum grease?
Lithium grease is commonly used in general maintenance. Formulations with molybdenum disulphide are aimed at certain mechanisms subject to loads, vibrations or slow movements.
Which NLGI grade is used in bearings?
NLGI 2 is common in many applications, but it is not valid for all bearings. Speed, temperature, load and greasing system may require another grade.
Are all greases suitable for centralised lubrication?
No. Pumpability, NLGI grade, ambient temperature, length of lines and the system manufacturer’s instructions must be checked.
