A Zerk fitting, also known as a grease fitting, is a small valve designed to deliver lubricant to various mechanical components. Determining the correct amount of grease to inject is crucial for proper equipment function and longevity. Over-greasing can lead to seal damage, while under-greasing results in premature wear and potential component failure. The specific quantity depends on factors like the component’s size, type, and operating conditions. Consulting the equipment’s service manual is essential for determining the appropriate lubrication intervals and grease volume.
Proper lubrication through these fittings protects machinery from friction, heat, and corrosion. This preventative maintenance extends equipment lifespan and reduces downtime caused by malfunctions. Historically, lubricating moving parts has been essential since the invention of simple machines. The development of the Zerk fitting, patented in 1929 by Oscar U. Zerk, streamlined the process, making lubrication more efficient and effective.
