Frequently Asked Questions
Q: What are the exact dimensions of the MS556001 bearing assembly?
A: The MS556001 features a 20 mm bore, 47 mm outer diameter, and 14 mm width. These dimensions are precision-engineered for standard manual pallet jack wheel axles and provide universal fit compatibility across multiple jack models from major manufacturers.
Q: What material and sealing system does the MS556001 use?
A: The MS556001 is manufactured from high-carbon chromium alloy steel for superior strength and corrosion resistance. It features double-lip rubber sealing to exclude moisture and contamination, and arrives pre-lubricated for continuous duty operation without requiring initial lubrication.
Q: Which manual pallet jack brands does the MS556001 fit?
A: The MS556001 is designed as a universal replacement bearing for manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, Linde, Clark, Mitsubishi, CAT, and BT. Verify your wheel axle dimensions (20 mm bore by 47 mm OD by 14 mm width) match before ordering.
Q: How long does the MS556001 bearing last under normal warehouse use?
A: The MS556001 provides extended service life due to its high-carbon alloy steel construction and double-lip sealed design. Pre-lubrication supports continuous duty operation. Bearing lifespan depends on load capacity, frequency of use, and environmental conditions. Premature wear may indicate wheel misalignment or bearing installation issues.
Q: What are the maintenance requirements for the MS556001 bearing?
A: The MS556001 is pre-lubricated and sealed, requiring minimal maintenance during normal operation. Periodically inspect for signs of noise, play, or resistance in wheel rotation. Do not attempt to disassemble or relubricate; replace the bearing assembly if wear becomes evident.
