Oil Free Washers

Lubrication-free washers are washers that don't require lubricating oil. They are also called oil-less washers. To prevent seizure or wear caused by heat from frictional resistance due to the load on the bearings, lubricant such as oil is usually used on washers. Lubrication-free washers can receive thrust loads without using lubricating oil. Normally, lubrication-free bushings that contain lubricating oil or lubricant are used in combination with the bearing main body. Since there is no need to refill lubricating oil, this type is very effective for working environments in which the use of lubricating oil is difficult. The lifespan of machines is also lengthened, reducing running costs such as maintenance. These parts are widely used, from large machines such as automobiles and general industrial machinery, to small electronic equipment.
