Frequently Asked Questions
Q: What is a grease fitting and why is it important?
A: SKU 3143133 is a grease fitting, also called a zerk fitting. It is a small valve that allows grease to be injected into bearings and moving joints while keeping dirt and contaminants out. Proper lubrication through grease fittings extends bearing life and prevents equipment failure.
Q: What equipment uses SKU 3143133?
A: This grease fitting is used in electric and manual lift truck applications, including pallet jacks, load wheels, steer wheel assemblies, and other bearing-equipped components from Crown, Toyota, Raymond, Yale, and similar manufacturers.
Q: How do I know if a grease fitting is damaged?
A: Check for leaking grease, cracks in the fitting body, bent or damaged threads, or missing internal check valves that prevent backflow. A damaged fitting will not hold grease pressure and allows contaminant entry into bearing locations.
Q: How often should grease fittings be inspected?
A: Grease fittings should be visually inspected weekly during equipment operation and replaced if bent, corroded, or leaking. Replace fittings if injection efforts indicate a blocked or stuck valve preventing grease flow.
