SU 9820-A

Frequently Asked Questions

Q: What are the detailed specifications of the SU 9820-A load wheel assembly?
A: The SU 9820-A features a 3.25-inch diameter polyurethane tread wheel bonded to a carbon steel core. The tread hardness is 95 Shore A polyurethane, and the wheel uses sealed ball bearings for corrosion resistance. The axle compatibility is 20 mm, and it is rated for 1200 lbs static load per wheel. This assembly is designed for electric lift truck applications.

Q: Is the SU 9820-A compatible with 20 mm axles, and what about other axle sizes?
A: The SU 9820-A is engineered specifically for 20 mm axles. If your pallet jack uses a different axle diameter, such as 1/2 inch, 5/8 inch, or another size, this wheel will not fit. Measure your axle diameter before ordering. Using an incompatible axle size will prevent proper installation and damage the wheel bearing bore.

Q: Can the SU 9820-A be used on both hydraulic and electric pallet jacks?
A: The SU 9820-A is designed for electric lift truck applications. While the wheel assembly itself is passive, confirm compatibility with your specific pallet jack model before installation. Some hydraulic jacks may use different wheel sizes or axle configurations. Verify fitment with the jack manufacturer or parts supplier.

Q: What is the static load rating, and what happens if I exceed it?
A: The SU 9820-A is rated for 1200 lbs static load per wheel. This is the maximum weight per wheel when the pallet jack is stationary. Exceeding this limit will accelerate bearing wear, flatten the polyurethane tread, and reduce wheel life. For heavy-duty applications, verify the total platform load capacity does not exceed the sum of all wheel ratings.

Q: How do I know if the SU 9820-A bearing or wheel is failing?
A: Signs of failure include grinding or squeaking noises from the wheel area, visible flat spots or chunks removed from the polyurethane tread, excessive wobble or play when manually spinning the wheel, or resistance when moving the pallet jack. Sealed bearings in the SU 9820-A should spin freely. Replace the assembly if any of these symptoms appear.

Q: Is the SU 9820-A wheel tread material suitable for all floor types?
A: The 95 Shore A polyurethane tread on the SU 9820-A is medium-hardness and suitable for most indoor concrete and smooth surfaces. It provides good grip and durability on typical warehouse floors. For outdoor or rough surfaces, verify that polyurethane is appropriate for your environment. Softer urethane (lower Shore A) is better for rough terrain, while harder material is needed for high-speed applications.
