A3X4

Frequently Asked Questions

Q: What are the specifications of the A3X4 load wheel?
A: The A3X4 features a 3-inch diameter with 3.66-inch hub length and 0.79-inch bore. The wheel has an aluminum core with 95A polyurethane tread and precision ball bearings. This configuration is designed for manual pallet jack applications.

Q: Which manual pallet jacks are compatible with the A3X4 load wheel?
A: The A3X4 is a direct replacement for multiple manual pallet jack brands including Crown, Toyota, Raymond, and similar OEM models with matching bore and hub dimensions. Verify your pallet jack bore size and hub length match the A3X4 specifications before ordering.

Q: What does the 95A polyurethane compound mean?
A: 95A polyurethane is a durable tread material rated on the Shore A hardness scale. This compound provides good traction and load handling characteristics on dry and lightly wet warehouse floors. It offers resistance to abrasion and typical warehouse chemicals.

Q: How long do the sealed bearings on the A3X4 last?
A: Sealed precision ball bearings are maintenance-free components. Wheel lifespan depends on load, usage intensity, and floor conditions. Most wheels operate 2-4 years before polyurethane tread wear requires replacement. Bearing failure is less common and usually indicates severe overload or impact damage.

Q: Can the A3X4 wheel be used on powered pallet jacks?
A: The A3X4 is specified for manual pallet jack applications. Electric or powered pallet jacks require load wheels rated for higher speeds and electrical contact requirements. Verify your equipment type before ordering. Contact us with your pallet jack model for the correct wheel specification.

Q: What is the bore size and how do I verify it matches my pallet jack?
A: The A3X4 has a 0.79-inch bore diameter. Measure the axle or spindle diameter on your pallet jack to confirm it matches. The hub length must also be 3.66 inches to ensure proper fitment and prevent wheel wobble or binding.
