Frequently Asked Questions
Q: What is the difference between the SU S9631-XL and the standard SU S9631?
A: The SU S9631-XL uses XL3 advanced bonding technology with a 97A durometer polyurethane compound, designed for maximum abrasion resistance and high duty cycle tolerance. The standard SU S9631 uses standard polyurethane. The XL variant is engineered for more demanding applications with higher floor speeds, frequent load cycles, or rougher floor surfaces.
Q: What does 97A durometer mean for the SU S9631-XL polyurethane?
A: 97A durometer measures polyurethane hardness on the Shore A scale. A 97A rating indicates a harder, more durable compound that resists abrasion and cuts better than softer compounds. This hardness extends tread life under heavy use but provides slightly less vibration dampening than softer urethane grades.
Q: What is XL3 bonding technology used in the SU S9631-XL?
A: XL3 is an advanced polyurethane bonding process that strengthens the adhesion between the polyurethane tread and the steel core. This prevents tread separation, delamination, and premature failure under high-speed operation and repeated load cycling. The result is longer wheel life in industrial environments.
Q: When should you upgrade to the SU S9631-XL instead of the standard S9631?
A: Upgrade to SU S9631-XL if your equipment sees more than 50 load cycles per shift, operates at higher speeds, runs on rough concrete, or is used 16+ hours per day. The enhanced durability justifies higher cost. For light-duty warehouse use under 20 cycles per shift, the standard S9631 is adequate.
Q: Is the SU S9631-XL a direct replacement for the standard SU S9631?
A: Yes, the SU S9631-XL is a direct bolt-on replacement for the standard SU S9631 if dimensions and bore size match your jack axle. However, verify that your equipment specifications approve the upgrade. Some lighter-duty jacks may not benefit from XL compound. Confirm compatibility with your jack model before purchasing.
Q: What maintenance is required for the SU S9631-XL?
A: The SU S9631-XL sealed bearing requires no lubrication. Inspect the tread for cuts, flat spots, or chunks every two weeks. Clean dirt and debris from the wheel to prevent bearing contamination. Replace when tread wear reaches 50 percent of original depth or if you observe bearing noise, wobbling, or resistance to rotation.
