Frequently Asked Questions
Q: What is the difference between SU 532 and SU 532-A?
A: SU 532 is the wheel only. SU 532-A is a complete load wheel assembly that includes the wheel, hub, bearings, and axle hardware pre-assembled. SU 532-A is plug-and-play for replacement; SU 532 requires hub and bearing installation.
Q: Can I install SU 532-A assembly on any lift truck with 3.25 inch wheels?
A: No. SU 532-A assembly is designed for specific axle and mounting configurations. Verify your truck model and year against the assembly documentation. Incorrect mounting causes misalignment, steering issues, and rapid bearing wear.
Q: Does SU 532-A come fully lubricated and ready to use?
A: SU 532-A assemblies are pre-lubricated at manufacture. Verify bearing type in the documentation—some use sealed bearings that never need additional grease, while others may require periodic lubrication. Do not over-grease sealed bearings as this causes heat and failure.
Q: What tools are required to replace SU 532-A assembly on my truck?
A: You will need basic hand tools including a socket set, jack, wheel blocks, and possibly a wheel puller if seized. Consult your truck service manual for specific torque specifications on axle nuts and mounting bolts. Improper torque causes wheel separation or bearing preload issues.
Q: What is the expected lifespan of SU 532-A assembly under normal use?
A: Under normal electric lift truck operation, SU 532-A assemblies typically last 3 to 5 years or 1000 to 2000 operating hours. Lifespan decreases with overloading, rough surfaces, high humidity, or lack of maintenance. Replace immediately if you hear grinding, feel vibration, or observe wheel runout.
