Product Description
BEARING assembly (SINGLE SHIELD)
Frequently Asked Questions
Q: What does single shield mean on this bearing assembly?
A: Single shield (SKU 3052276) means one side of the bearing assembly has a protective metal shield to exclude dirt and debris. The other side is open. This design is used in applications where the non-shielded side interfaces with the equipment housing or pump body.
Q: Which pallet jack models use this single shield bearing assembly?
A: This assembly fits manual pallet jacks from Crown, Toyota, Raymond, Yale, and equivalent OEM brands designed with single-shield bearing specifications. Check your equipment manual or existing part number to confirm compatibility before ordering.
Q: How does a single shield bearing perform compared to sealed or double-shield designs?
A: Single shield bearings offer moderate protection at lower cost. They perform well in relatively clean indoor warehouse environments but offer less protection than sealed bearings in wet or dusty conditions. Choose sealed or double-shield designs if your pallet jack operates in cold storage, outdoor, or high-contamination areas.
Q: What maintenance is required for this single shield bearing assembly?
A: Lubricate this assembly every 500 to 1,000 hours or per your OEM schedule. Monitor the open side for debris accumulation and clean as needed. Proper lubrication is critical because the single shield provides less protection than sealed designs.
Q: What is the material and load rating of this bearing assembly?
A: This bearing assembly uses hardened steel raceways and rolling elements rated for the standard load capacities of manual pallet jacks (typically 4,000 to 6,000 pounds depending on model). The single shield design maintains the load rating while reducing sealed bearing complexity.
Q: Can I upgrade from a single shield to a sealed bearing assembly?
A: Sealed bearing assemblies require compatible housing and may have different dimensional specifications. Do not substitute without confirming that bore diameter, outer diameter, and width match your equipment. Verify compatibility before ordering a sealed replacement.
