RA 305620-000-A

Frequently Asked Questions

Q: What components are included in the 305620-000-A assembly?
A: The 305620-000-A is a complete load wheel assembly consisting of a machined cast iron hub, precision-sealed deep groove ball bearings, and a molded Shore 95A polyurethane tread. It arrives as a ready-to-install unit requiring no sub-assembly.

Q: What is the difference between 92A and 95A polyurethane hardness ratings?
A: Shore hardness measures polyurethane durometer. The 95A compound is harder and more durable than 92A, delivering longer tread life under heavy loads and abrasive floor conditions. The 95A specification prioritizes service life over maximum floor grip characteristics, making it ideal for high-utilization equipment.

Q: Why is cast iron used for the hub?
A: Cast iron hubs provide superior structural integrity and dimensional stability under heavy load conditions typical of electric lift truck applications. Cast iron resists deformation, maintains precise bearing clearances throughout extended service life, and handles shock loading from equipment operation without warping or fatigue cracking.

Q: How do I verify compatibility with my Raymond equipment?
A: The 305620-000-A is designed for Raymond electric pallet trucks and lift trucks. Verify that your equipment model and bearing bore size match this assembly specification. Cross-reference with your equipment documentation or contact technical support with your equipment serial number for compatibility confirmation.

Q: What maintenance do sealed bearing assemblies require?
A: Sealed precision ball bearings are maintenance-free under normal operating conditions. Do not attempt to relubricate or disassemble sealed bearing units. During equipment operation, inspect for unusual noise, wobbling, or grinding resistance. If bearing play develops, the entire assembly should be replaced, as bearing repairs are not practical in field service.

Q: What storage conditions are recommended for this assembly?
A: Store the assembly in a clean, dry environment protected from moisture and corrosive materials. Keep the assembly in its original packaging until ready for installation. Avoid exposure to extreme temperatures or direct sunlight. For long-term storage, inspect periodically for corrosion or bearing seal degradation.
