Open gear lubrication: a serious challenge

Open gear lubrication - BardahlBecause open gears are not oil-tight, oil can not be used as a lubricant, but greases are used in various types. Open gears often have to function under (extremely) difficult conditions. Gear transmission as these are generally exposed to the most difficult conditions such as moisture, sand, dust, rain, cold, heat, etc.

Open gear lubrication therefore requires a grease that meets the following requirements:
• a very strong adhesive lubricating film
• provide protection against corrosion
• Reduce wear
• Good lubrication under varying conditions

Of course, these are general points. Below is a list of various lubricants that we can offer you.

Lubricants for open gears: 

Bardahl BIO Synthetic Grease (biodegradable grease)

Bardahl Bio Synthetic Grease has got an outstanding sealing capacity and a very good resistance to water action, combined with a high adherence on the mechanism to lubricate.
Bardahl Bio Synthetic Grease must be used whenever the lubricant is an important contaminating factor and wherever uncontrolled lubricant losses may pass to the soil or to water.
Thanks to its biodegradable properties it has got better performances and higher efficiency in further water treatments, being physic-chemical biological ones.
The eventual contamination of soils, cultures, forests, water, will have a lower effect, due the high biodegrading velocity, moreover when compared tot the conventional greases.

Benefits
The main benefits of the Bardahl Bio Synthetic Grease are:
• Anticorrosive capacity
• Outstanding water resistance
• High adherence
• Biodegradability

Bardahl Ceramic Paste (High temperature grease)

Bardahl Ceramic Paste is a release and mounting paste. It is a balanced combination of very fine ceramic parts, a non-melting grease and special anti- corrosion and anti-oxidation inhibitors. Bardahl Ceramic Paste is metal free. Melting temperature ceramic 3000°C.

Advantages
• Rapidly and easy mounting of wire connections.
• Prevents corrosion
• Gives a quick and easy release of bold/nut connections, even after exposure to high temperatures with peaks up to 1650°C, corrosive atmospheres or extreme pressures.
• Reduces wear on places with high friction.
• Will prevent corrosion by acids, salt or caustics.
• Will not be washed away by water.

Applications
The ceramic parts of Bardahl Ceramic Paste will fill the irregularity on the surface. The available film will not cure, lump or melt and will not break down by trembling, shrinkage or expansion. During the use, for example when tightening a bolt, the surface will be honed by the ceramic parts. Because of this a strongly adhered film on the treated metals will arise. At the same time the treated parts will be cut off from the atmosphere.

Bardahl Industrial Lithium Grease 00 and 2/3 (universal grease)

Bardahl Industrial Lithium Grease is a high quality, multi-purpose, lithium based grease recommended for general industrial and automotive applications. It is designed for application requiring a superior friction and wear reducing grease lubricant in temperature ranges from -20°C to +150°C. This grease is ideal for most construction, industrial, farm and automotive uses and is available in NLGI grades #00 and #2. Bardahl Industrial Lithium Grease “00” can be used in centralized systems.

The problem
A modern machinery runs under high stress which overloads grease lubricants. Inadequate lubrication, under these conditions, can increase heat, friction, and wear leading to higher maintenance costs and power consumption. These high loads can also break down the hydrodynamic grease film which separates metal surfaces, leaving these surfaces without lubrication. In many industrial and construction environments moist or corrosive conditions exist. These conditions can lead to bearing failures when grease lubricants are not designed to protect against rust.

The action
Bardahl Industrial Lithium Grease is a blend of lithium soap, high grade mineral oil and special extreme pressure additives (12-hydroxy stearate). This combination provides a superior full film grease lubricant. Additionally, the additives form a molecular film that clings to metal surfaces lubricating when the hydrodynamic grease film is broken. The extreme pressure agents work to protect metal surfaces against rust and corrosion.

Applications
Bardahl Lithium Multipurpose EP Grease is successfully used for the lubrication of very heavy tax working agriculture machines, cranes, excavators, freight carriages and private cars as well as most of industrial the applications.

Open Gear & Wire Compound (protect and conserve)

Bardahl Open Gear & Wire Compound is specially formulated for use on exposed gears, wire ropes and chain/sprocket drives. This product is designed to provide extra protection against wear, rust and corrosion, even under severe operating conditions.
The problem
Open gear mechanisms are typically subject to adverse conditions including high service loads, exposure to the elements, and contamination from dirt and other abrasive materials. Wire ropes and chains are often exposed to corrosive conditions, and are subjected to abrasion and temperature extremes. Rapid corrosion and wear under these severe conditions, can cause excessive down time and high replacement costs.

 

The action

Bardahl Open Gear & Wire Compound is a penetrating lubricant for cables and wire ropes which provides a resilient coating that won’t be thrown off or washed out. On open gears, it provides a durable adhesive coating which protects against contamination, corrosion, and wear due to high pressure and heat. Bardahl OGW Compounds are ideal for protecting equipment such as turn buckles, shackles, cable clamps, exposed bolts, levers and switches against adverse environmental conditions.

Applications
• Protection of cables, open cog wheels of taps, dragline excavators, excavators etc.
• Protection of agriculture – and ground resistance machines, as well as articulation points of cars such as pedals, car doors, brake systems etc.
• Protection and conserving of steel cables, as well as cable transits.
• Protection of open cog wheels, collars, cables, role-lower which itself under water and if in the immediacy of are substance, coal dust and mud
• Protection of rolling mill-lower against corrosion and of all surfaces, which work in an acid atmosphere such as open cog wheels in paper factories, cement factories etc.
• Protection of components of mud mills and lock doors which are continuously immersed in water (also water salts).
• Occur of rust of crap and wreck, if lubricated for assembly, like e.g. at car expresses frameworks, feather straps, bumpers – and other affirmatives which will not be demonstrated under not favourable circumstances for a long time. These applications are of course also applied in the industry and shipping.

Bardahl TF Dry (dry lubricant with PTFE)

Bardahl TF Dry is a concentrated synthetic lubricant scientifically compounded for dry lubrication and extreme pressure, based on Teflon basis. It reduces friction and prevents sticking. It is an unique all-purpose lubricant for numerous applications. After application it dries instantly leaving a dry, non-oily, clean, PTFE-powder surface, the slipperiest substance known to science. This product will function under a wide variety of conditions, ranging from cryogenic temperatures to 260°C or higher.

The problem
Assembly of equipment with close tolerances requires lubricant, which will not be scraped off during break in. Normal oils and greases, even ones containing graphite of molybdenum-disulfide, do not adequately meet this specialized requirement.
Chains and conveyors need a lubricant with high penetrating and corrosion resistant properties, as well as one which contains a minimum level of oil or slow evaporating solvent in order to prevent “fling off” and attraction of grime to lubricated parts.
Certain industrial applications require not only good lubrication but also the ability of the lubricant to remove existing grime to maintain or improve performance.

The working
Bardahl TF Dry will form an effective lubricating surface on any material – wood, metal, leather, plastic, elastomers, fibers, glass, etc. A thin coating can easily be applied by the aerosol package. The lubricating protecting film is very thin, very adhesive, non-oily and will penetrate in the smallest places. It has an extremely low friction coefficient and will therefore reduce “stick-slip” problems to a minimum.
Characteristics
• Is a non-oily clean dry lubricant.
• Dries very fast and leaves no oil film or wax.
• It will not collect dirt or dust.
• Resists corrosion by acids or alkali’s.
• Will not be affected by water, oil or solvents.
• Prevents materials sticking in molds, bins, tanks, etc.
• Will not melt or freeze.

Applications
• Sliding mechanisms, nuts, bolts, cables, tools, conveyors – anywhere a dry powder lubricant is required up to 260°C.
• For lubricating pump-shafts and valve stems just prior to installing packing, and in the installation of flange gaskets for easier disassembly.
• As breaking-in lubricant for packings (prevents sticking). A light coating on the wearing surfaces of the packing and shaft will provide extra protection during critical start-up period of newly installed packing.
• For conveyers, slides, mechanisms requiring a non-staining lubricant.
• For drawer sliding surfaces and windows.
