Bearing Assembly for Manual Pallet Jacks

Frequently Asked Questions

Q: What are the key features of the 6306Z2 bearing?
A: The 6306Z2 features a single-row deep groove ball design with dual metal shields, precision-ground raceways, and durable steel construction. It is engineered for high radial load capacity and long service life in manual pallet jack wheel and pump assemblies.

Q: What is the difference between the 6306Z and 6306Z2 designations?
A: The 6306Z2 uses dual metal shields (two shields, both sides) compared to the 6306Z which has a single metal shield. The dual shield design (Z2) provides increased protection against contaminants and moisture while still allowing for controlled lubrication access.

Q: What equipment does the 6306Z2 bearing fit?
A: The 6306Z2 is compatible with standard manual pallet jack wheel and pump assemblies. It fits models from major OEM brands including Crown, Toyota, Raymond, Yale, and Hyster. Verify the bearing bore and outer diameter match your specific equipment model.

Q: What materials is the 6306Z2 constructed from?
A: The 6306Z2 is constructed from precision bearing steel for the rings and rolling elements, providing durability and high load capacity. The dual metal shields protect the internal bearing surfaces from moisture and dust contamination.

Q: How does the dual shield design affect bearing performance?
A: Dual metal shields significantly reduce contamination ingress and moisture exposure, which extends bearing service life and reduces maintenance requirements. The shields maintain bearing cleanliness better than open or single-shield designs, particularly in wet or dirty warehouse environments.
