Product Description
BEARING assembly (SINGLE SHIELD)
Frequently Asked Questions
Q: What is the single shield design on this bearing assembly?
A: Single shield design includes one protective metal or plastic shield on the bearing. This shield provides dust and debris exclusion while allowing some ventilation. Single shield bearings are less sealed than double shield or sealed bearing assemblies but offer lower drag.
Q: Which manual pallet jack models use SKU 3736687?
A: This bearing assembly fits load wheel applications on manual pallet jacks from Crown, Toyota, Raymond, Yale, and other OEM manufacturers. Verify bearing bore diameter and width match your equipment before ordering.
Q: What is the rated load capacity for equipment using this bearing?
A: Single shield bearing assemblies are suitable for manual pallet jacks with rated load capacities up to approximately 5,500 lbs. Exceeding rated load capacity causes premature bearing wear, friction, and failure.
Q: How does the single shield compare to a sealed bearing?
A: Single shield bearings have lower initial cost and reduced drag compared to fully sealed assemblies. However, they offer less protection in wet or contaminated environments. Sealed or double shield designs are better for cold storage or washdown areas.
Q: What is the typical service life of this bearing assembly?
A: Service life depends on load cycles, floor conditions, and maintenance. This bearing typically lasts 2 to 4 years in standard warehouse use. Increased friction, noise, or resistance when pushing the pallet jack indicates bearing wear requiring replacement.
