Frequently Asked Questions
Q: What are the specifications of the CR 073961-XL-A load wheel assembly?
A: The CR 073961-XL-A features a 6 inch outer diameter polyurethane wheel with 4.25 inch tread width and 3.149 inch bore diameter. The wheel includes integrated shoulder bearings and is manufactured in 97A Shore durometer (XL designation compound). This assembly is designed for 4000-5000 lb capacity applications and fits Crown PR Series pallet trucks.
Q: Is the CR 073961-XL-A wheel suitable for freezer and cold storage environments?
A: Yes. The CR 073961-XL-A is specifically rated for freezer environments, wet conditions, and metal debris exposure. The 97A durometer compound maintains hardness in cold temperatures where softer compounds become tacky. The XL-designation polyurethane compound provides high traction on wet and icy surfaces encountered in cold storage warehouse applications.
Q: What are the cross-reference part numbers for the CR 073961-XL-A?
A: The CR 073961-XL-A carries alternate designations: 073961, 73961, and generic part number CR 73961-A. The OEM part number CR 073961-XL-A is the primary identifier. When ordering replacement parts, reference the exact part number to ensure you receive the XL-compound wheel assembly rather than standard variants.
Q: How does the integrated shoulder bearing design affect maintenance?
A: Integrated shoulder bearings are sealed bearing assemblies that do not require field lubrication. This design reduces maintenance frequency compared to separate bearing installations. When shoulder bearings begin to deteriorate, the entire wheel assembly must be replaced rather than just the bearing. Listen for increased grinding or resistance to rotation as indicators that bearing replacement is needed.
Q: What load capacity should I verify before using CR 073961-XL-A wheels?
A: The CR 073961-XL-A is rated for 4000-5000 lb capacity applications. Verify that your Crown PR Series pallet truck is not rated above 5000 lb and that the wheel bore matches the 3.149 inch specification on your equipment spindle. Exceeding rated capacity accelerates bearing wear and polyurethane compound degradation.
Q: How does the 6 inch diameter compare to other Crown load wheel sizes?
A: The 6 inch diameter is larger than standard 4 inch wheels, providing better floor clearance and improved stability when navigating uneven warehouse floors or warehouse door thresholds. The larger diameter reduces friction and polyurethane compound wear on smooth, level concrete but may be slower to respond in tight-turn applications. Verify wheel bore and axle compatibility before replacing smaller wheels with the 6 inch CR 073961-XL-A.
