Frequently Asked Questions
Q: What is the difference between SU S2365-A and SU S2365-EZ-A?
A: Both wheels are 3.250 inch diameter x 4.500 inch width with identical core specifications. The main difference is that SU S2365-A is a poly load wheel assembly, while SU S2365-EZ-A is marketed as a load wheel assembly with emphasis on the EZ mounting system. If your existing truck uses standard mounting, verify the hub interface before ordering to confirm fitment compatibility.
Q: Can I use SU S2365-A wheels on an electric pallet jack rated for 6000 pounds?
A: Verify the original equipment weight rating and load per wheel. The 3.250 inch diameter wheel with Cushothane XL material is designed for electric lift truck applications. Do not exceed the truck manufacturers rated load capacity. If your application is significantly different from standard electric lift trucks, contact the equipment OEM to confirm wheel compatibility and load limits.
Q: What should I check if a SU S2365-A wheel shows flat spots or uneven wear?
A: Flat spots typically indicate the wheel was locked during transport or the truck sat stationary under load. Check for stuck brake mechanisms, misaligned steering, or debris jamming the wheel. Inspect the hub for bent or damaged steering knuckle mounts. Uneven edge wear suggests alignment issues or worn kingpins. If wear is minor and the wheel rolls smoothly without vibration, it may remain in service; replace if vibration or binding occurs during operation.
Q: Is installation of SU S2365-A a bolt-on replacement or does it require modification?
A: SU S2365-A uses a standard 1.938 inch inside diameter bore with 2.0467 inch bore outside diameter and 0.593 inch bore depth. Installation is bolt-on replacement if the hub bore and steering knuckle match these specifications. Remove the cotter pin and castle nut from the steering knuckle, slide the wheel off, install the new wheel, and reinstall hardware. Torque to manufacturer specifications typically 40 to 60 foot-pounds; verify in your specific truck manual.
Q: How often should SU S2365-A wheels be replaced under normal operating conditions?
A: Service life depends on load, surface, and usage hours. Cushothane XL material typically provides 12 to 24 months of service in standard warehouse environments with daily 4 to 8 hour operation. Replace wheels when tread thickness drops below 0.125 inches, surface cracks appear, or the wheel no longer rolls freely. Inspect wheels monthly for visible damage, debris buildup, and rotation smoothness.
Q: What is the metric equivalent size for SU S2365-A wheels?
A: SU S2365-A wheels measure 82.55mm diameter x 114.30mm width in metric dimensions. When ordering replacement wheels internationally or cross-referencing with non-US suppliers, verify both imperial and metric specifications to ensure correct fitment, as metric sizing may round differently.
