Product Description
Crown polyurethane load wheel engineered for electric lift truck applications. This direct replacement features a 4.00 inch outside diameter with 2.047 inch bore and 2.88 inch tread width. Available in 95A-97A Shore durometer compounds to optimize performance for your specific operating conditions. The softer 95A compound delivers superior floor grip and protection; the harder 97A compound extends wheel lifespan in high-cycle warehouse environments. Cross-reference number 4816552 confirms broad compatibility across Crown electric lift equipment. Premium polyurethane construction delivers reliable, consistent performance in demanding material handling operations.

Frequently Asked Questions
Q: What are the exact dimensions of the CR 073961-402-A load wheel?
A: The CR 073961-402-A features a 4.00 inch outside diameter, 2.047 inch bore, and 2.88 inch tread width. These specifications match Crown OEM part number 073961 and cross-reference to OEM number 4816552. Verify bore fit before ordering to ensure compatibility with your equipment spindle.
Q: What durometer options are available for the CR 073961-402-A?
A: This load wheel is manufactured in 95A-97A Shore durometer compounds. The standard compound provides good floor grip and moderate wear resistance for general warehouse applications on electric lift trucks. Select 95A for softer compound if floor protection is critical; 97A offers increased hardness for longer wheel life in heavy-use environments.
Q: Which Crown electric lift truck models use the CR 073961-402-A wheel?
A: The CR 073961-402-A is designed for Crown electric lift truck applications with this wheel diameter and bore specification. Cross-reference to OEM 4816552 confirms compatibility with specific Crown models. Verify your equipment serial range and model designation to confirm fitment before purchase.
Q: How does polyurethane compound durometer affect load wheel performance?
A: Higher durometer (97A) wheels resist wear longer but transmit more vibration and offer less grip on wet or slippery surfaces. Lower durometer (95A) wheels provide better traction and floor grip but wear faster under heavy loads. Choose based on your application: wet floors and tight maneuverability favor 95A; high-cycle warehouse use and concrete floors favor 97A.
Q: What is the typical lifespan of a CR 073961-402-A polyurethane wheel?
A: Polyurethane load wheels typically last 12-24 months depending on usage intensity, floor type, and load frequency. The CR 073961-402-A will show visible tread wear and flat spots as it approaches end of service life. Replace when diameter loss exceeds 0.25 inch or when flat spots exceed 0.125 inch depth to maintain even floor contact and prevent equipment instability.
Q: How should CR 073961-402-A wheels be maintained to extend lifespan?
A: Inspect wheels monthly for debris embedded in the tread, flat spots, and visible cracks. Clean polyurethane compound regularly to remove chemical residue from warehouse floors. Ensure bearing lubrication is adequate (wheels should spin freely by hand without grinding noise). Rotate load distribution across all wheels when possible to promote even wear.
