Frequently Asked Questions
Q: What is the purpose of the GW 9143, and how does it differ from load wheels like the GW 9141-XL?
A: The GW 9143 is a Durarun idler or support caster wheel, not a primary load wheel. Idler wheels guide and stabilize the load path in electric lift trucks. Load wheels carry the primary weight. The GW 9143 at 4.000 x 2.500 inches is designed to roll smoothly with minimal noise and friction. Load wheels bear direct load stress. Never use an idler wheel in a load position, as it will fail quickly under sustained pressure.
Q: Does the GW 9143 come as a tire-only or as a complete assembly with bearings?
A: The GW 9143 specifications indicate solid polyurethane construction but do not clearly state whether bearings are pre-installed. Contact your supplier with your OEM part number (GW 9143 or cross-reference GW 9143-A-SG, GP 9143-A-SG, GW 9143-A1, or GP 9143-A1) to confirm whether you are receiving a tire-only or an assembly. This determines whether you need to source and install separate bearings.
Q: What OEM equipment uses the GW 9143, and are there cross-reference part numbers?
A: The GW 9143 is used on industrial electric lift trucks and material handling casters. Cross-reference OEM part numbers include GW 9143-A-SG, GP 9143-A-SG, GW 9143-A1, and GP 9143-A1. Always verify your exact equipment serial number and OEM documentation before ordering. If your manual references any of these numbers, they are likely compatible with the GW 9143.
Q: How does the 95A durometer of the GW 9143 affect ride quality and noise?
A: The 95A durometer polyurethane provides a balance of hardness and resilience, designed to roll smoothly and reduce operational noise compared to harder compounds. The solid polyurethane construction dampens vibration better than metal casters. This makes the GW 9143 ideal for environments where operator comfort and low noise are important. The wheel is not soft enough for high grip but firm enough to reduce chattering and wear.
Q: What are signs that the GW 9143 needs replacement?
A: Replace the GW 9143 if you notice grinding noises, increased vibration, flat spots, visible cracks, or if the wheel no longer rolls smoothly. Idler wheels experience less direct load than load wheels but still wear over 12-18 months depending on duty cycle. If the jack pulls to one side or feels unstable, check all idler wheels for wear. Replace as a set on both sides when possible to maintain balanced handling.
