RA 305620-000-A

Frequently Asked Questions

Q: What does the RA 305620-000-A assembly include?
A: The RA 305620-000-A is a complete load wheel assembly consisting of a cast iron hub, precision-sealed deep groove ball bearings, and a molded 95A polyurethane tread. It comes as a ready-to-install unit for Raymond electric pallet trucks and lift trucks, eliminating the need for component assembly.

Q: What is the difference between 92A and 95A polyurethane compounds?
A: Shore hardness ratings measure polyurethane durometer. The 95A compound is harder and more durable than 92A, providing longer tread life under heavy loads and abrasive floor conditions. The 95A trades some floor grip characteristics for extended service life. Choose 95A for high-utilization equipment and 92A for general duty applications.

Q: Why is cast iron used for the hub in the RA 305620-000-A?
A: Cast iron hubs provide excellent structural integrity and dimensional stability under heavy load conditions typical of electric lift truck applications. Cast iron resists deformation, maintains precise bearing clearances over extended service life, and handles shock loads from equipment operation without warping or cracking.

Q: Is the RA 305620-000-A equivalent to other load wheel assemblies?
A: The RA 305620-000-A is the OEM assembly for Raymond electric pallet trucks. Verify that your equipment model and bearing size match this assembly before ordering. Cross-reference with your equipment documentation or contact us with your equipment serial number for compatibility verification.

Q: What maintenance is required for sealed bearing assemblies?
A: Sealed precision ball bearings are maintenance-free under normal operating conditions. Do not attempt to relubricate or open sealed bearing assemblies. Inspect for unusual noise, wobbling, or resistance during equipment operation. Replace the entire assembly if bearing play develops, as bearing repairs are not practical in field applications.
