Frequently Asked Questions
Q: What makes the SU STR2001-RA caster assembly different from standard casters?
A: The SU STR2001-RA features a compressive PolyBlock polyurethane damper that absorbs vibration and impact during heavy-duty lifting operations. The sealed wheel bearings and zinc-plated steel body provide corrosion resistance and extended service life.
Q: What is the cross-reference part number for the SU STR2001-RA?
A: The SU STR2001-RA cross-references as STR2001-RA, SUSTR2001-RA, and SU-STR2001-RA. Always order using the exact SKU SU STR2001-RA to ensure you receive the correct damped assembly variant.
Q: Is the SU STR2000-RA housing compatible with the SU STR2001-RA caster assembly?
A: Yes. The SU STR2000-RA is the caster housing designed for the SU STR2001-RA assembly. If you need only the housing, order the SU STR2000-RA separately. If you need a complete replacement caster, order the full SU STR2001-RA assembly.
Q: Which electric truck models are compatible with the SU STR2001-RA?
A: The SU STR2001-RA is compatible with electric pallet trucks in the STR1000 Series specification range. Verify your truck model and serial number to confirm compatibility before installation.
Q: How do I diagnose if the SU STR2001-RA damper is failing?
A: A failing damper manifests as increased vibration when the truck is in motion, a spongy or unstable feel during load handling, or visible damage to the polyurethane block. Replace the entire caster assembly if damper failure is suspected.
Q: What is the load capacity of the SU STR2001-RA caster?
A: Load capacity is determined by your truck model and configuration. Consult your truck manual for total rated capacity. The SU STR2001-RA supports the same per-wheel load rating as the standard SU STR2001 but with enhanced vibration dampening.
