BEARING assembly (SINGLE SHIELD)
Frequently Asked Questions
Q: What is a single shield bearing assembly and how is it used on pallet jacks?
A: A single shield bearing assembly is a sealed rolling bearing with one metal or rubber shield on the outer race to protect the bearing from contamination. On manual pallet jacks, these bearing assemblies are installed in load wheel centers and steering pivot points to enable smooth rotation under load.
Q: Which pallet jack models and load wheel types is bearing assembly SKU 300111 compatible with?
A: This single shield bearing assembly fits standard load wheel assemblies on manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, and similar OEMs. Verify inner bore diameter, outer diameter, and width against your wheel specification before ordering to ensure correct fit.
Q: What is the load rating and durability of this bearing assembly?
A: Single shield bearing assemblies are designed for continuous rolling under static load (pallet jacks can support 5,500 lbs at the load wheel). Bearing life depends on proper lubrication, misalignment prevention, and load distribution. Expect 2,000 to 5,000 operating hours before replacement becomes necessary under normal warehouse use.
Q: When should the bearing assembly 300111 be replaced?
A: Replace the bearing assembly if the load wheel exhibits grinding noise, rough rotation, play or wobble in the wheel, or if grease leaks from the shield. Bearings cannot be repaired and must be replaced as a unit. A failing bearing reduces steering control and increases pallet jack pushing effort.
Q: What maintenance does this bearing assembly require?
A: Single shield bearings are sealed and require no user lubrication. Inspect periodically for grease loss or contamination at the shield. Keep mounting surfaces clean to prevent misalignment. Bearing assemblies cannot be disassembled or relubricated; replace if seal is compromised.
