Frequently Asked Questions
Q: What is a grease fitting and what does SKU 446357 do?
A: SKU 446357 is a grease fitting (also called a zerk fitting) used on forklift pivot pins, mast bearings, and articulation joints. It allows pressurized grease to be injected into lubricated components without disassembly. Standard fitting size is 1/4-28 NPT thread.
Q: Which forklift brands use this grease fitting?
A: This fitting is compatible with electric and internal combustion forklifts from Crown, Toyota, Raymond, Yale, Hyster, Clark, and CAT. Verify the thread size and location on your specific model before ordering, as fitting sizes vary across manufacturers.
Q: How often should this fitting be serviced or replaced?
A: Grease fittings should be inspected monthly and replaced every 2 to 3 years or if the fitting becomes damaged, seized, or leaks grease. Worn or seized fittings prevent proper lubrication and accelerate wear on mast pins and bearings. Replace immediately if the fitting cannot be accessed with a grease gun.
Q: What material is this grease fitting made from?
A: SKU 446357 is typically manufactured from zinc-plated steel or stainless steel. Zinc-plated versions are standard for most indoor/outdoor applications. Stainless variants offer better corrosion resistance in wet or cold storage environments. Verify material compatibility with your equipment specifications.
