PROVEN INTEGRITY. DELIVERING VALUE.
Plain & Self-Lubricating Bearings: Since bearings generally have a high frictional resistance that leads to heat, lubricants such as oil or grease are used to prevent seizing or abnormal wear that could otherwise cause this frictional heat. Lubrication-free bushings do not need lubricating oil because the bearing housing has a lubricating structure that is made possible by lubricating oil in the bearing housing or by embedding solid lubricants, etc. Since they do not require lubricating oil, lubrication-free bushings are often used for applications such as precision machinery that makes it difficult to replenish lubricating oil and equipment with low affinity for oil. They also significantly reduce maintenance costs, eliminating the need for regular lubrication and allowing stable operation for long periods. Lubricated bushings come in a variety of shapes that can be used for different applications as needed. Examples include straight bushings, collar bushings, flange bushings, and housing bushings.
