Frequently Asked Questions
Q: What does the 95A hardness rating mean on the SU S629?
A: The 95A Shore A hardness rating indicates the tread material stiffness. A 95A rating means the SU S629 polyurethane tread is moderately firm, providing good grip on smooth warehouse floors while resisting wear. Softer durometers (90A) grip better but wear faster; harder durometers (98A+) last longer but may slip on smooth floors.
Q: What are the exact dimensions of the SU S629?
A: The SU S629 has an outside diameter of 3.25 inches (82.55mm), width of 5.937 inches (150.80mm), inside diameter of 1.938 inches, bore depth of 0.591 inches, hub width of 5.873 inches, and bore outside diameter of 2.0467 inches. These specifications ensure proper fitment on electric pallet jack front axles.
Q: Is the SU S629 suitable for outdoor material handling?
A: The SU S629 can be used outdoors on smooth, sealed concrete. However, the 95A polyurethane tread will wear faster on rough outdoor surfaces, aggregate-exposed concrete, and asphalt. For frequent outdoor use, consider a higher durometer compound (98A or higher) for extended service life.
Q: Can I interchange the SU S629 with the SU S628-XL?
A: No. Although both have identical outer diameters and widths (3.25 x 5.937), the SU S629 has a hub width of 5.873 inches while the SU S628-XL hub width is 5.937 inches. This 0.064 inch difference will cause binding or play depending on your axle design. Use the exact OEM part number specified for your lift truck.
Q: What floor conditions are ideal for the SU S629?
A: The SU S629 performs best on smooth, clean warehouse floors (polished concrete, sealed composite, or vinyl). It provides excellent steering response and tread durability under these conditions. On rough, unsealed concrete or with dirt and debris, steering effort increases and tread wear accelerates.
