221N

Frequently Asked Questions

Q: What equipment does the 221N manual pallet jack wheel and bearing set fit?
A: The 221N is designed as a replacement wheel and bearing assembly for Rol-Lift brand manual pallet jacks. The set includes nylon load wheels and 6204-2RS radial ball bearings (20 mm bore, 47 mm outer diameter, 14 mm width) with double rubber seals. The wheel diameter is 2-15/16 inches with a 3-9/16 inch hub length. Verify your pallet jack model and serial range match Rol-Lift specifications before ordering.

Q: What is the wheel material and durometer rating for the 221N?
A: The 221N wheels are manufactured from nylon with a hardness rating of 70D (Shore D). This hardness provides good floor grip and durability for general warehouse and manufacturing environments. The nylon material resists chemicals and moisture better than polyurethane but offers less traction on wet or slippery floors compared to high-traction compounds.

Q: Can the 221N wheels be used in cold storage or on wet floors?
A: The 221N nylon wheels are rated for general purpose use. For consistent performance in cold storage (below 32 degrees Fahrenheit) or on wet or contaminated floors, consider alternative wheel compounds with higher traction properties. Nylon wheels may become slippery in cold environments or when wet, affecting operator control and safety.

Q: What is the load capacity of the 221N wheel and bearing assembly?
A: The load capacity depends on your complete pallet jack configuration and weight distribution across all wheels. The 6204-2RS bearings used in the 221N are standard deep-groove ball bearings rated for radial loads typical of manual pallet trucks in the 2,000 to 5,000 pound range. Always verify your equipment rated capacity and ensure all wheels and bearings are in good condition to maintain safe operation.

Q: How long do the 221N bearings last and what is the maintenance requirement?
A: The 6204-2RS double-sealed bearings in the 221N require no lubrication maintenance since they are factory sealed. Bearing lifespan varies based on usage intensity, floor conditions, and load distribution but typically ranges from 2 to 5 years in normal warehouse service. Replace the entire 221N wheel and bearing assembly if bearings become rough, noisy, or develop side play in the hub.

Q: Are the 221N wheels compatible with other pallet jack brands or only Rol-Lift?
A: The 221N is specifically designed for Rol-Lift manual pallet jacks. While the wheel dimensions (2-15/16 inches diameter, 3-9/16 inch hub length) may be similar to other brands, the axle mounting and bearing specifications are proprietary to Rol-Lift. Do not attempt to force-fit 221N wheels onto other brands, as this can result in wheel binding or axle damage. Cross-reference your specific pallet jack OEM part number to ensure correct fitment.
