Frequently Asked Questions
Q: What is the difference between the 2777378 and the CL 2777378-SG?
A: The CL 2777378-SG includes integrated string guard protection in addition to the standard caster wheel assembly. The string guard prevents rope, cord, and debris from wrapping around the wheel and axle during operation, reducing snag hazards in warehouse environments.
Q: What are the wheel specifications for the CL 2777378-SG?
A: The CL 2777378-SG features a polyurethane wheel with a bore. The wheel has a 95A Shore hardness durometer rating, providing superior wear resistance and floor grip for electric lift truck applications.
Q: What does the 95A Shore hardness rating mean for this wheel assembly?
A: The 95A Shore hardness rating indicates a moderately hard polyurethane compound. This hardness level provides excellent wear resistance and floor grip while maintaining reasonable flexibility and load-bearing capacity for typical warehouse pallet truck duty.
Q: Is the string guard removable on the CL 2777378-SG?
A: The string guard is an integrated component of the CL 2777378-SG assembly and is not designed for removal. If string guard protection is not required, the standard 2777378 without the guard is the appropriate choice.
Q: How should this wheel assembly be maintained?
A: Inspect the wheel regularly for uneven wear, cracks, or debris accumulation around the string guard. Clean any debris from the guard to maintain snag protection. Monitor the polyurethane compound for cuts or gouges that may affect performance. Replace if damage compromises wheel integrity or load capacity.
