Frequently Asked Questions
Q: What are the key specifications of the SU 2400-XL-A Load Wheel Assembly?
A: The SU 2400-XL-A features a 3.25-inch diameter polyurethane tread (90 Shore A nominal), machined steel core with powder coat finish, precision-sealed ball bearing (high carbon chromium steel per ISO 683/17), 20 mm axle fitment, and 1.15 maximum service factor. This is a complete pre-assembled unit ready for bolt-on installation on compatible electric lift trucks.
Q: Is the SU 2400-XL-A compatible with Yale, Crown, Toyota, and Nissan lift trucks?
A: The SU 2400-XL-A has a 20 mm axle bore, which is a common OEM standard. However, compatibility is not guaranteed across all brands and model years. Verify your truck uses a 20 mm axle and confirm the mounting flange diameter and bolt pattern match before ordering. Contact the truck manufacturer with your specific model and serial range to confirm fitment.
Q: What does a 1.15 maximum service factor mean for the SU 2400-XL-A?
A: The service factor of 1.15 indicates the wheel can safely handle 15 percent above its rated load capacity under normal operation. Do not exceed this limit even in short bursts. Continuous operation above the service factor or sudden shock loads (such as aggressive cornering at speed) will cause premature bearing wear, seal failure, and tread separation. Stay within rated load limits.
Q: How do I diagnose if the SU 2400-XL-A bearing seal is failing?
A: Signs of bearing seal failure include visible grease leakage around the seal, a squeaking or grinding noise when the wheel rotates, play or wobble in the wheel when grasped and moved side to side, or excessive heat on the bearing after 2-3 hours of operation. Spin the wheel by hand—if it stops abruptly or feels rough, the bearing is compromised. Replace the entire SU 2400-XL-A assembly. Do not attempt field bearing replacement.
Q: What installation torque should I use for the SU 2400-XL-A axle bolt?
A: Tighten the 20 mm axle bolt to 45-55 foot-pounds (60-75 Newton-meters) for most electric lift trucks. Check your truck service manual for the exact specification. Use a calibrated torque wrench to avoid over-tightening, which compresses the bearing seal and causes premature wear. If the bolt is loose, tighten incrementally and recheck after the first 8 hours of operation.
Q: What is the expected lifespan of the SU 2400-XL-A assembly under continuous warehouse duty?
A: Under continuous 8-hour-per-day warehouse operation with proper load limits and maintenance, expect 18-24 months of service life. In lighter duty cycles (4-5 hours per day), life extends to 30-36 months. The bearing lifespan depends on proper axle bolt torque, load limits, and floor conditions. Uneven wear or early failure indicates improper installation, overloading, or floor damage.
