Frequently Asked Questions
Q: What are the key specifications and material differences between the SU S9135-EZ and standard SU S9135?
A: The SU S9135-EZ is 3.25 inches outer diameter by 5 inches width, matching the SU S9135 size. The primary difference is the hub material: SU S9135-EZ uses a steel hub for enhanced load capacity and corrosion resistance, while the standard SU S9135 has a cast iron hub. The SU S9135-EZ also features a corrosion-resistant finish and high-durability polymer wheel construction with an integrated ball bearing.
Q: Is the SU S9135-EZ suitable for wet or corrosive warehouse environments?
A: Yes. The SU S9135-EZ steel hub and corrosion-resistant finish provide superior durability in humid, wet, or salt-spray environments compared to the cast iron SU S9135. The high-durability polymer tread resists chemical damage. However, verify with the manufacturer that the SU S9135-EZ is approved for your specific environmental conditions, especially if chloride or caustic chemicals are present.
Q: Does the SU S9135-EZ require a different spindle diameter than the SU S9135?
A: The SU S9135-EZ manufacturer part number is listed as SU S9135-EZ-A. The product description indicates the bore specifications and hub materials differ from standard S9135. Verify your jack spindle diameter matches the SU S9135-EZ bore specification before purchase. Do not assume the SU S9135-EZ has the same 20mm bore as the SU S9135 without confirmation.
Q: What is the expected lifespan of the SU S9135-EZ wheel in heavy-duty warehouse use?
A: The steel hub and high-durability polymer construction typically provide 18 to 24 months of service life in heavy daily use, compared to 12 to 18 months for standard cast iron wheels. Actual lifespan depends on floor type, load weight, and environmental conditions. Inspect every 6 months for tread wear, checking for flat spots or cracks. Replace when tread depth is significantly reduced.
Q: Can the SU S9135-EZ be substituted for a standard SU S9135 in an existing pallet jack?
A: The SU S9135-EZ may be compatible if spindle diameter and hub width specifications match your jack. However, always verify bore ID and width before purchasing. The steel hub design offers advantages over cast iron, but incorrect bore sizing will cause wobbling or binding. Consult your jack manufacturer or a parts supplier if you are unsure about substitutability.
Q: How do I test whether the SU S9135-EZ bearing is functioning properly after installation?
A: After installation, manually push the jack and observe wheel rotation. The wheel should spin freely and smoothly without grinding, squeaking, or catching noises. Grasp the wheel rim and attempt to move it side to side; there should be no discernible play. If the wheel binds, produces noise, or has excessive side play, remove it and inspect the spindle for damage. A faulty bearing requires wheel replacement.
