High speed bearing grease
High speed bearing grease
Furniture machinery low noise / high velocity bearing grease
High-speed bearing lubrication requires low-viscosity oils or specialized greases to minimize internal friction, heat generation, and oil churning, typically used when the bearing pitch diameter in mm x RPM exceeds 500.000
Woodworking drilling spindle lubrication grease
Range of greases allowing operation at very high speeds, in particular in systems where oil greasing is not practicable.
Traditional greases cannot operate effectively at high speeds. With speed, assemblies warm up and standard grease can be ejected, finally resulting in breakage of the equipment.
High-speed greases are formulated with special thickeners and oils allowing them to approach the functionality of oil while keeping the sealing properties required in this type of mechanism. One of the parameters to take into account is the speed factor
The speed factor is a term that helps define the relationship of the speed at which a bearing rotates with 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 bearing inner diameter multiplied by the speed at which it rotates. The second method is known as the NDm value. This uses the bearing’s median size, also known as the pitch diameter, and the rotation speed to calculate the speed factor.
The speed factor can help you determine a variety of lubricant properties, which you can then utilize to select the proper lubricant. Among these properties would be the viscosity of the oil and the National Lubricating Grease Institute (NLGI) grade of the grease for the application.
