Grease fitting
Frequently Asked Questions
Q: What is a grease fitting and what does it do?
A: A grease fitting, also called a zerk fitting or grease nipple, is a one-way valve connection point that allows grease to be injected into bearings, pivot points, and joints on forklifts. It prevents backflow and contaminant entry while providing lubrication access without disassembly.
Q: Which forklift types and brands use grease fittings?
A: Grease fittings are found on internal combustion and electric forklifts from Crown, Toyota, Raymond, Hyster, Jungheinrich, Linde, Clark, Mitsubishi, CAT, and BT. They are standard on mast cylinders, load backrest cylinders, and articulating joints across all forklift types.
Q: How often should grease fittings be serviced and lubricated?
A: Grease fittings on high-use forklifts typically require servicing every 50 to 200 operating hours depending on duty cycle and environmental conditions. Heavy-duty applications in dirty or wet environments require more frequent lubrication. Check your equipment manual for the specific maintenance schedule.
Q: What happens if a grease fitting fails or becomes clogged?
A: A failed or clogged grease fitting prevents lubrication from reaching critical joints and bearings. This leads to accelerated wear, increased friction, rough operation, and potential bearing seizure or joint damage if left unaddressed. Replace clogged fittings immediately to restore proper lubrication.
Q: Are there different sizes and types of grease fittings?
A: Yes, grease fittings come in different thread sizes, profiles, and valve designs. Common sizes include 1/8 NPT and 1/4 NPT. Verify the exact thread size and profile of SKU W8006685 against your forklift documentation to ensure correct replacement fitment.
