Load Wheel Poly 97A 3 x 4.5 in
Frequently Asked Questions
Q: What does 97A hardness mean on the SU S3365-XL-A poly wheel?
A: 97A is the Shore A durometer rating, which measures poly wheel hardness. 97A is a medium-hard compound, stiffer than 85A but softer than 100A. The 97A on the SU S3365-XL-A provides better wear resistance on concrete and reduced rolling resistance compared to softer compounds, making it ideal for high-volume warehouse operations.
Q: Is the SU S3365-XL-A compatible with lift trucks rated for 5000 lb?
A: Yes. The 3 x 4.5 inch wheel size on the SU S3365-XL-A supports heavy-duty forklifts and wide-base pallet jacks rated up to 6000 lb. The XL designation indicates extra load capacity. However, verify your truck manual lists a 3 x 4.5 inch wheel; installing an oversized wheel on underated trucks causes steering and braking problems.
Q: How does the SU S3365-XL-A differ from standard load wheels?
A: The SU S3365-XL-A is wider (4.5 inches vs. 2.625 inches on standard wheels) and features a 97A hardness poly compound. The larger footprint distributes load more evenly, reducing puncture risk and improving stability on uneven surfaces. The harder compound resists abrasion better than softer alternatives, extending wheel life by 20 to 30 percent in high-use environments.
Q: Can the SU S3365-XL-A be used on both load and steer wheel positions?
A: Only on load wheels. The SU S3365-XL-A is designed for rear wheel (load) applications. Using this large assembly in steer positions causes excessive steering force and uncontrollable turning. Always use manufacturer-specified steer wheels (typically SU S329 or equivalent) in front positions.
Q: What is the expected lifespan of the SU S3365-XL-A in cold storage?
A: In cold storage (below 32 degrees Fahrenheit), the 97A poly compound becomes brittle and prone to cracking. Lifespan drops to 8 to 12 months of continuous operation. For freezer applications, request a specialized low-temperature poly wheel (typically 85A durometer). Standard SU S3365-XL-A wheels are rated for room temperature to 100 degrees Fahrenheit operation.
Q: How do I verify the SU S3365-XL-A will fit my truck without modification?
A: Measure your wheel well clearance in three places: directly above the wheel (vertical clearance), on the outer edge (horizontal clearance), and front-to-back. The SU S3365-XL-A is 4.5 inches wide, so it requires at least 5 inches of side-to-side space. If clearance is less than 4.75 inches, frame modification or a narrower wheel is needed. Contact your truck manufacturer for approval before installation.
