Crown Pw Pr Series Polyurethane Load Wheel Assembly

Frequently Asked Questions

Q: What are the dimensions and bearing configuration of the CR 77084-1-A?
A: The CR 77084-1-A is a polyurethane load wheel assembly. The -A designation indicates it includes an integrated bearing assembly. Available in standard configuration and variants with different bearing specifications. Verify your equipment bearing type before ordering to ensure the correct variant is selected.

Q: What polyurethane durometer options are available for the CR 77084-1-A?
A: The CR 77084-1-A is primarily manufactured with 95A Shore hardness polyurethane for standard warehouse material handling. Related variants include the CR 77084-SU-XL, which uses 97A Shore hardness for slightly higher load capacity and wear resistance. Review the specific variant part number to confirm the durometer rating, as 95A and 97A compounds have different performance characteristics on concrete and composite flooring.

Q: What cross-reference and variant part numbers relate to the CR 77084-1-A?
A: The CR 77084-1-A base part number is CR 77084. Related variants include CR 77084-XL-A, CR 77084-SU-XL, CR077084-101, and 77084-302. Cross-referencing these numbers confirms inventory and helps identify if alternative variants may suit different operational requirements. Always order by the exact part number that matches your equipment nameplate.

Q: Which Crown PW and PR series pallet trucks does the CR 77084-1-A fit?
A: The CR 77084-1-A is designed for Crown PW and PR series manual pallet trucks. This assembly is a direct replacement for the legacy 77084 wheel position on these models. Verify the wheel and bearing socket type on your equipment before ordering to confirm compatibility with the integrated bearing assembly.

Q: What is the difference between the standard CR 77084-1-A and the SU-XL variant?
A: The CR 77084-SU-XL variant uses a harder polyurethane compound (97A Shore vs. 95A Shore in the standard assembly), providing increased wear resistance and load capacity for heavy-duty continuous use. The SU-XL is suitable for operations with frequent high-load cycles or abrasive floor conditions. Standard 95A rating is sufficient for typical warehouse material handling. Order the variant that matches your operational intensity.

Q: How should this load wheel be stored and maintained?
A: Store the CR 77084-1-A in a clean, dry environment away from direct sunlight and extreme temperatures. Polyurethane wheels should be kept away from oils, solvents, and chemical cleaners that may cause degradation. Before use, visually inspect the wheel for cracks, flat spots, or visible wear. Clean the wheel with mild soap and water as needed. Proper storage extends the service life of polyurethane wheels and maintains optimal performance.

Q: How long does the CR 77084-1-A typically last in warehouse applications?
A: The lifespan of the CR 77084-1-A depends on operational intensity, floor conditions, and load cycles. Under typical warehouse conditions with moderate use on concrete flooring, a polyurethane wheel can perform reliably for 12-24 months or more. Heavier use, abrasive floors, or extended high-load cycles will reduce lifespan. Regular inspection helps identify wear early. The 97A variant (SU-XL) offers extended life compared to 95A in demanding applications.
