Frequently Asked Questions
Q: What equipment does the 503389 poly load wheel fit?
A: The 503389 is a polyurethane load wheel compatible with electric lift trucks from manufacturers including Crown, Toyota, Raymond, and Yale. Verify your equipment model and serial range against our compatibility chart before ordering.
Q: What does the 97-A durometer rating mean for this load wheel?
A: The 97-A specification indicates Shore A hardness. This harder polyurethane compound provides extended wear life and resists deformation under sustained loads, making it ideal for high-volume warehouse operations.
Q: How does polyurethane compare to rubber for load wheels?
A: Polyurethane load wheels like the 503389 offer superior durability, longer service life, and better performance on wet or cold storage floors compared to rubber alternatives. Polyurethane resists oil and chemical exposure better than rubber.
Q: What is the typical lifespan of the 503389?
A: Polyurethane load wheels typically last 3000-5000 operating hours depending on load weight, floor conditions, and maintenance. Harder compounds like 97-A generally outlast softer formulations in continuous-use environments.
Q: How should I maintain this load wheel during storage?
A: Store the wheel in a cool, dry location away from direct sunlight and extreme temperatures. Protect from ozone, solvents, and harsh chemicals. Inspect periodically for cracks or wear patterns before returning to service.
Q: Is the 503389 a direct replacement wheel?
A: The 503389 is an aftermarket load wheel assembly compatible with multiple lift truck platforms. Confirm compatibility with your specific equipment model before ordering to ensure proper fit and performance.
