BEARING assembly (SINGLE SHIELD)
Frequently Asked Questions
Q: What does single shield construction mean on SKU 2640018?
A: Single shield construction on SKU 2640018 provides protection from one side of the bearing raceway. A stamped steel or brass shield is pressed onto one side to help prevent large particles and contaminants from entering the bearing, while the opposite side remains open. This design allows grease to redistribute more freely compared to double-sealed bearings, reducing drag.
Q: Which manual pallet jack models use SKU 2640018 bearing assembly?
A: SKU 2640018 is designed as a wheel bearing for manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, and other standard manufacturers. Verify your equipment OEM part number matches before ordering. The single shield design is common in load wheel applications where slight protection is needed without restricting wheel rotation.
Q: Is SKU 2640018 suitable for wet or outdoor warehouse environments?
A: SKU 2640018 with single shield provides moderate protection from moisture and debris. While the shield reduces direct water splash and large particle ingress, it is not waterproof. For extended exposure to wet conditions, freezer environments, or outdoor use, double-sealed or contact-sealed bearing assemblies provide better protection. Consider your operating environment before selecting this part.
Q: What is the typical load rating for SKU 2640018?
A: SKU 2640018 is engineered for standard manual pallet jack duty, supporting wheel loads typically ranging from 3000 to 6000 pounds depending on your equipment configuration. Verify your pallet jack rated capacity and distribute loads evenly across all wheels to avoid exceeding individual bearing load limits.
Q: How often should SKU 2640018 be replaced in normal warehouse operation?
A: With normal manual pallet jack operation and quarterly inspection, SKU 2640018 typically provides 18-24 months of service life. Replacement is recommended when wheel rotation becomes noisy, rough, or requires excessive pushing force. Environmental factors, material spills, and dust buildup reduce lifespan; clean wheels and axles regularly to extend bearing life.
