Frequently Asked Questions
Q: What does STD ZERK CAST L/W mean for the SU S9880?
A: STD indicates standard construction. ZERK refers to a Zerk fitting (grease nipple) for manual lubrication. CAST refers to a cast metal hub. L/W indicates load wheel. This wheel features a grease point for periodic maintenance.
Q: What are the dimensions of the SU S9880?
A: The SU S9880 is an 8 inch outer diameter by 2 inch width load wheel. These dimensions make it suitable for standard reach trucks and three-wheel balance designs in typical warehouse applications.
Q: How often should I apply grease through the Zerk fitting?
A: Apply 2 to 3 pumps of NLGI Grade 2 lithium-based grease every 500 operating hours or monthly, whichever comes first. Over-greasing can increase friction and heat. Wipe excess grease from the wheel hub.
Q: What type of grease is compatible with the SU S9880?
A: Use NLGI Grade 2 lithium-based general purpose grease. Do not use food-grade, molybdenum disulfide, or extreme pressure (EP) greases, as these can damage seals and alter bearing performance.
Q: Is the SU S9880 suitable for wet floors or refrigerated environments?
A: The standard SU S9880 is designed for dry to moderately damp warehouse floors. For continuous wet floor or cold storage below 32 degrees Fahrenheit, contact our technical team regarding specialized tire compounds or sealed bearing configurations.
Q: What load rating does the SU S9880 have?
A: Load capacity depends on the truck configuration and number of wheels. Do not exceed the truck nameplate load limit. For a specific load rating, provide your truck model and serial range, and we can verify the maximum safe load per wheel.
