Frequently Asked Questions
Q: What equipment does the CT 971757-XL load wheel fit?
A: The CT 971757-XL is a direct fit for Caterpillar electric pallet jacks and electric lift trucks. This 200 mm diameter wheel with 20 mm axle bore is designed for continuous-duty electric equipment. Verify your equipment bore diameter matches 20 mm before ordering, as bore mismatch will prevent proper fitment.
Q: What is the durometer rating and what does it mean for this wheel?
A: The CT 971757-XL features a 97A Shore durometer polyurethane compound, which is a high-hardness formulation. The 97A rating indicates excellent wear resistance and load-carrying capacity for continuous-duty applications. Higher durometer ratings mean faster wear in general material handling, but this grade is specifically engineered for electric lift truck environments where consistent performance is required.
Q: What core material is used in the CT 971757-XL, and why does it matter?
A: The CT 971757-XL uses a machined steel core, which provides structural rigidity and load distribution. The machined finish ensures precise axle bore tolerancing and concentricity, critical for balanced wheel rotation and axle longevity. Steel cores resist deformation under continuous electric truck duty cycles better than softer alternatives.
Q: How long should the CT 971757-XL typically last in service?
A: Lifespan depends on load weight, floor conditions, and duty cycle. In typical continuous-duty electric lift truck service, the 97A polyurethane compound will outlast softer polymers but will eventually glaze and harden. Expect 2-4 years of active service before tread performance degrades, though the steel core remains serviceable. Track wear by monitoring grip on wet or contaminated floors.
Q: What is the tread width, and does it affect compatibility?
A: The CT 971757-XL has a 50 mm tread width. Tread width must match your equipment fork arms or wheel carriage slots. A wheel that is too narrow will wobble; one that is too wide will not fit in the frame. Always confirm your current wheel width before ordering as replacements.
Q: Does this wheel require maintenance or periodic inspection?
A: The CT 971757-XL should be visually inspected monthly for signs of glazing, flat spots, or debris contamination. The machined steel core is maintenance-free, but the polyurethane tread will lose grip as it hardens. Clean wheels regularly with mild detergent and water; avoid harsh solvents that can degrade the polyurethane. Monitor for uneven wear patterns, which may indicate misalignment or bearing issues.
