High Speed Grease

UNIFLEX 15

Corfin Lubrication brand Unifex 15 high speed grease is produced using synthetic hydrocarbons, esters and barium complex compounds to ensure high performance. It is an ideal lubricating grease for the lubrication of needle roller bearings.
Package: 1 kg, 20 kg
Delivery Date: 1-3 Weeks

High Speed Grease Advantages

Unifex 15 provides maximum protection against corrosion and wear. It is also a product that is resistant to water, chemical environments and oxidation. Due to its high pumpability, high speed bearing grease supports the uninterrupted operation of machines in centralized lubrication systems.

Unifex 15 has been developed as a complete high speed grease. Thanks to its complex structure, barium does not lose its absorption capacity even at high pressures. It is mostly preferred in needle bearings and high-speed plain bearings.

It is used in CNC lathe head bearings because it operates smoothly even at high speeds. Since high speed grease does not lose its protective properties against cutting fluids, it is frequently preferred in applications where there is a risk of liquid splashing on the bearings.

Offers a wide operating temperature range of 40 / 130 °C

It shows very good working stability even in chemical environments.

It is perfectly compatible with plastic and elastomer materials.

High Speed Grease Features

High Speed Grease Usage Areas

It is used in all bearings and bearing housings that need special engineering services and have to work under aggressive conditions.
It is used in all high-speed systems where needle roller bearings operate.
High speed grease is used in sleeve bearings in the textile industry and in all bearings operating at high speed and high temperature.
High speed grease is preferred in all high-speed CNC mirror bearings where the risk of contact with cutting fluids is high.

High Speed Grease Frequently Asked Questions

Conventional greases cannot work effectively at high speeds. As speed increases, assemblies become hot and standard grease can be expelled, eventually causing the equipment to break. High-speed greases are formulated with special thickeners and oils that allow the oil to maintain its functionality while maintaining the sealing properties required in such mechanisms. One of the parameters to be taken into consideration is the speed factor. The NDm of the bearing to be lubricated is expressed as follows. N = speed limit of the bearing in rpm and Dm = median diameter of the bearing in mm. Often these greases have properties that allow them to reduce noise from bearings at these high speeds (low noise greases). Thus, they guarantee appropriate use to the end consumer. High-speed greases show a special rheological behavior: they become liquid under shear and provide lubrication close to that of an oil. When not moved, they return to their consistency and guarantee tightness. These strong thixotropic events are provided by the thickener. Lithium greases with low soap or even higher polyurea content are best suited to these speed restrictions. Control of the production process to deliver highly thixotropic greases with low noise. Base oils of low viscosity (10 to 100 cSt) and usually of synthetic origin (PAO, synthetic esters). Use of friction modifiers and antioxidant combinations for minimum wear and optimized service life.
The most important physical property of a lubricant is viscosity. Viscosity is what determines how thick or thin the lubricating film will be depending on load, speed and surfaces in contact. This should suit the needs of the bearing bed. Most general-purpose greases have a base oil viscosity of approximately 220 centistokes. While this type of grease can work well at moderate speeds and loads, when bearing speed increases the viscosity must be reduced accordingly. There are many ways to calculate viscosity. Using the speed factor mentioned previously, you can use standardized charts to determine the appropriate viscosity for the bearing at operating temperature.
Speed factor is a term that helps describe the relationship between the rotational speed of a bearing and the size of the bearing. There are two main ways to calculate this factor. The first is known as the DN value, which uses the inner diameter of the bearing multiplied by the rotational speed. The second method is known as NDm value. This uses the bearing’s median size, also known as pitch diameter, and rotational speed to calculate the speed factor. The speed factor can help you determine various lubricant properties that you can use to select the appropriate lubricant. These properties include the viscosity of the oil and the National Lubricating Grease Institute (NLGI) grade of the grease for the application.
Base Oil Viscosity – Make sure the viscosity provides enough lubricating film but not so thick that it causes excessive heat and friction. Channeling Features – Must be able to direct grease in such a way that excessive heat is not generated from grease agitation. Dropping Point – The dropping point of the grease should exceed the operating temperature by a wide margin to prevent excessive leakage and possible bearing failure. Thickener Type – Choose a thickener that can provide proper dropping point, channeling and leakage properties. Also, if you use more than one grease, check the compatibility of thickener types in case of accidental mixing. NLGI Grade – The consistency of the grease will have an impact on the flow properties and channeling properties of the finished lubricating grease. Additive Load – Many applications require additives to improve the performance of the grease. A wide variety of chemical and solid additives can be mixed for greases to aid film strength and reduce friction and wear.

THE IMPORTANCE OF CHOOSING THE CORRECT HIGH-SPEED GREASE
Most industrial facilities have bearings that spin faster than normal processing equipment. When it comes to lubricating these pieces of equipment, not all lubricants behave the same.

For grease-lubricated components, the effects of grease on bearings can lead to increased heat, friction, and ultimately premature failure.

By correctly selecting a high-speed grease that can handle these high speeds, it is possible to help minimize possible failures caused by incompatibility with the application of the lubricant.

One of the most important considerations when choosing a high-speed grease is the temperature at which the bearing will operate. To ensure that the selected grease works at high temperatures, the dropping point of the grease must be checked.

A high dropping point is important for bearings operating at high temperatures. However, just because a grease has a high dropping point does not mean that the base oil can withstand high temperatures. The dropping point does not equal the maximum usable temperature. There must be a buffer between the temperature at which the bearing operates and the high-speed grease dropping point.

HOW SHOULD GREASE CHANGE BE DONE?
When changing grease types, it is important to remove as much of the old grease as possible to minimize any incompatibility problems with the new high speed grease. If necessary, the equipment should be disassembled and as much grease removed as possible.

While most applications will be properly lubricated with a general purpose grease, for situations where the NDM value is extremely high, it is critical to ensure the lubricant can protect the equipment. Therefore, even if a high-speed grease with all the features is selected, the only way to truly know whether the grease will perform as desired is to conduct a field trial.

To do this, bearing temperature should be monitored and checked for grease or oil leaks from seals or discharge vents. Finally, it is necessary to ensure that the NDM values of the bearings are calculated in order to select the appropriate lubricant. With careful oil selection, high-speed equipment will have a longer service life.
