Frequently Asked Questions
Q: What is the KA 74878390 and what are its primary applications?
A: The KA 74878390 is a polyurethane load roller designed for electric lift trucks. It is used as a replacement part for equipment from manufacturers like Komatsu, Crown, Toyota, and Raymond where poly rollers are specified.
Q: What dimensions should I verify before ordering the KA 74878390?
A: Verify the outer diameter, tread width, hub width, and axle bore size against your existing roller or equipment specifications. Mismatched dimensions will prevent proper fitment and can damage your lift truck.
Q: How does the KA 74878390 compare to other poly load rollers?
A: The KA 74878390 is an OEM-specification polyurethane roller. Performance characteristics depend on durometer hardness and compound type. Compare the durometer rating and bond technology to equivalent parts to assess relative durability and grip properties.
Q: Is the KA 74878390 suitable for use on wet floors?
A: Standard polyurethane load rollers offer moderate wet-floor traction. If your operation involves consistent wet floor operation, confirm the compound specification. Some polyurethane formulations provide superior wet-floor grip compared to others.
Q: What is the expected service life of the KA 74878390?
A: Polyurethane load roller lifespan typically ranges from 12 to 24 months in standard warehouse duty. Heavy-duty operation, abrasive floors, or wet environments accelerate wear and may shorten replacement intervals.
