Frequently Asked Questions
Q: Can I swap SU S376-XL wheels between different jack models?
A: SU S376-XL wheels can be swapped between jack models as long as the existing axle diameter matches the 2.8341 inch bore OD and the jacks load ratings are compatible. The -XL designation typically indicates reinforced hub or higher load tolerance. Do not install SU S376-XL on a standard-duty jack if the nameplate rating is lower than the wheels capacity, as this can mask overload conditions and damage the jack frame.
Q: What is the bore depth specification for SU S376-XL and why does it matter?
A: The SU S376-XL bore depth is 0.739 inch. This specification ensures the hub seats fully on the axle shoulder without binding or tilting. Incorrect bore depth will cause the wheel to sit proud of the axle nut, allowing side-to-side play that damages bearings and causes squealing. Always measure bore depth when retrofitting jacks from other manufacturers.
Q: Why would I choose SU S376-XL over the standard SU S376-A?
A: Choose SU S376-XL if your jack performs heavy-duty lifting (frequent full-load cycles), operates on rough floors, or runs longer shifts. The -XL typically features a thicker hub wall, larger bearing cavity, or higher-grade Cushothane compound that resists wear and deformation better than standard versions. Standard SU S376-A is adequate for light to medium duty applications with typical pallet weight ranges.
Q: How do I diagnose if an SU S376-XL wheel bearing is failing?
A: Bearing failure symptoms include: (1) squealing or grinding noise when rolling the jack, (2) wheel remains spinning longer than normal when spun by hand (indicates low friction or loose fit), (3) grinding noise that worsens under load, (4) wheel running hot to touch after use. If the wheel spins but makes noise, lubricate first. If noise persists after lubrication, the bearing is damaged and the entire wheel assembly must be replaced.
Q: What is the metric equivalent size for SU S376-XL?
A: SU S376-XL is equivalent to 127.00mm diameter x 76.20mm width in metric units. If you are sourcing parts from international suppliers or comparing to European specifications, use these metric dimensions. Always convert back to inches when ordering from US-based manufacturers to avoid diameter mismatches.
Q: How often should SU S376-XL wheels be rotated on a jack with four wheels?
A: Rotate wheels every 6-12 months or when wear becomes visible on one wheel before others. Heavy-use jacks benefit from quarterly rotation. Rotate diagonally (front-left to rear-right and vice versa) to balance wear patterns. If rotation does not even out wear, your jack may be out of alignment or the floor may be uneven, requiring frame inspection or floor preparation.
