Frequently Asked Questions
Q: Is the SU STR2000-RA equivalent to Raymond OEM part STR2000RA or STR2001-RA?
A: Yes. The SU STR2000-RA is a direct equivalent to Raymond OEM STR2000RA and supersedes the SU STR2001-RA. All three part numbers are interchangeable and have identical specifications, fitment, and load ratings. Use any of these parts without affecting truck operation.
Q: What does the offset kingpin-less design in the SU STR2000-RA provide?
A: The offset kingpin-less machined cast steel housing improves steering response and reduces play compared to traditional kingpin designs. The housing also provides better lateral support and more even load distribution across the wheel. This design reduces shimmy and extends caster life.
Q: What are the side plate thickness specifications for the SU STR2000-RA?
A: The SU STR2000-RA has side plate thickness ranging from 0.25 to 0.375 inches depending on load zone. The thicker sections reinforce high-stress areas. Do not modify or bend the side plates, as this will compromise structural integrity and void the warranty.
Q: How does the zinc plating on the SU STR2000-RA prevent rust?
A: The rust-proof zinc plating creates a protective barrier against moisture and salt exposure. This is especially important for trucks used in wet environments or near loading docks with salt spray. The zinc coating will naturally develop a white patina over time, which indicates the protective layer is working.
Q: What is the wheel diameter and material for the SU STR2000-RA?
A: The SU STR2000-RA is equipped with a 4-inch diameter polyurethane wheel. The polyurethane compound provides good grip on both dry concrete and slightly wet floors. For operations in cold storage or frequent wet floor use, order the SU STR2000-RA-EZ variant with high-traction polyurethane compound.
Q: How do I diagnose if the SU STR2000-RA has a linear deflection or positive stop issue?
A: Linear deflection allows controlled fork tine flex during load handling and is by design. Check that the caster has a positive stop that prevents the housing from deflecting excessively beyond its design limit. If the housing rocks loosely or allows extreme deflection, the kingpin or mounting bolts may be loose. Tighten all fasteners and retest.
