Frequently Asked Questions
Q: What are the cross-references for the SU S10210-A load wheel assembly?
A: The SU S10210-A is a proprietary assembly. No direct cross-reference equivalents from Yale, Hyster, or Crown are available. Always verify your specific electric lift truck model and serial range before ordering. Substituting with non-equivalent assemblies will result in fitment failure and potential safety hazards.
Q: Is the SU S10210-A compatible with both 24V and 36V lift trucks?
A: The SU S10210-A assembly itself is voltage-agnostic and works with all DC voltage systems. However, you must confirm the assembly matches your truck model and serial range. Verify the bearing type, bore diameter, and hub width against your truck documentation. Incorrect fitment will prevent wheel rotation and damage the steering linkage.
Q: What tools and steps are required to install the SU S10210-A?
A: Installation requires a socket wrench set, bearing puller, and press (if replacing existing assembly). Remove the cotter pin and axle nut, slide the old assembly off, clean the axle, then slide the new assembly on. Press firmly until the hub seats fully against the shoulder. Do not overtighten the axle nut or the bearing will bind. Use a new cotter pin and bend both prongs completely.
Q: What is the typical load capacity and duty cycle for the SU S10210-A?
A: The SU S10210-A is rated for standard warehouse duty cycles on electric lift trucks up to 8000 pounds carrying capacity. Load limits vary by truck model and axle configuration. High-duty or outdoor applications may exceed the assembly rating and cause premature bearing failure. Consult your truck specification sheet for exact load ratings.
Q: How do I diagnose if the SU S10210-A bearings are failing?
A: Symptoms of bearing failure include grinding noise, wheel wobble at speed, steering resistance, and heat buildup in the hub area. Spin the wheel by hand; it should rotate smoothly with minimal friction. If movement is rough or the wheel locks up, the bearings are seized and the entire assembly must be replaced. Do not continue operating; seized bearings can cause loss of steering control.
Q: What is the expected service life of the SU S10210-A?
A: Under normal warehouse conditions, the SU S10210-A typically lasts 18 to 36 months depending on daily usage, floor conditions, and maintenance. Rough or outdoor floors reduce life to 12 to 18 months. Inspect the assembly every 6 months for bearing play, wheel wobble, and corrosion. Sealed bearings do not require lubrication but cannot be serviced; replacement is the only option.
