Frequently Asked Questions
Q: What is the IU BR-103 bearing cup used for?
A: The IU BR-103 is a bearing cup component used in load wheel assemblies and drive wheel assemblies on manual and electric pallet jacks. It serves as the outer race for roller bearings and supports axle rotation under load.
Q: What material is the IU BR-103 bearing cup made from?
A: The IU BR-103 bearing cup is typically constructed from steel or hardened steel alloy. This material provides the durability needed to support rolling contact loads and resist wear over extended service life.
Q: Which pallet jack models use the IU BR-103 bearing cup?
A: The IU BR-103 fits wheel assemblies on pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, and Clark equipment. Verify the exact wheel assembly model and axle diameter to confirm fitment before ordering.
Q: What symptoms indicate the IU BR-103 bearing cup needs replacement?
A: Replace the bearing cup if wheels exhibit: grinding or squealing noises during operation, excessive play or wobbling, uneven wear patterns, or rough rotation. These indicate internal bearing races are damaged and the cup must be replaced as an assembly.
Q: Can the IU BR-103 be cross-referenced across different pallet jack brands?
A: Bearing cup dimensions must match exactly for fitment. Verify bore diameter, cup width, and mounting face specifications. Many equivalent part numbers exist across Crown, Toyota, Raymond, and Yale if dimensions align.
Q: How often should the IU BR-103 bearing cup be inspected?
A: Inspect bearing cups quarterly in standard environments or monthly in wet or cold storage settings. Check for noise, vibration, or resistance during wheel rotation. High-cycle operations may require more frequent inspection.
