Frequently Asked Questions
Q: Can I upgrade from SU 532-A to SU 534-A assembly on my lift truck?
A: Only if your truck frame and axles are rated for wider wheels. SU 534-A is wider (6.25 inches vs 3 inches) and heavier, increasing turning radius and steering effort. Contact your truck manufacturer to confirm your model supports this upgrade before ordering.
Q: What metric dimensions should I reference when ordering SU 534-A assembly?
A: SU 534-A is 82.55mm diameter by 158.75mm width. Use these metric dimensions when cross-referencing with international suppliers or documentation. Always confirm both diameter and width to ensure you receive the correct assembly.
Q: Is installation of SU 534-A assembly the same as SU 532-A?
A: The assembly process is similar, but SU 534-A requires a longer axle rod to accommodate the 6.25 inch width. Check your truck manual for the correct axle length and mounting torque specification. Improper axle length causes wheel side-to-side movement and accelerated bearing wear.
Q: How much more load can SU 534-A handle compared to SU 532-A?
A: Both assemblies have the same 3.25 inch diameter and are rated for identical maximum loads per your truck specifications. The wider SU 534-A distributes that same load over a larger footprint, improving traction and reducing floor stress, but does not increase load capacity.
Q: Do SU 534-A bearings require more frequent maintenance than SU 532-A bearings?
A: Not necessarily. Sealed bearing maintenance is identical regardless of wheel width. However, the wider SU 534-A experiences different load distribution that may extend bearing life. If your bearings are grease-packed, follow the 6 to 12 month relubrication schedule for both assemblies.
