Sealed Precision Bearing Assembly for Manual Pallet Jack Load Wheel

Frequently Asked Questions

Q: What is the ND99605Z bearing assembly designed for?
A: The ND99605Z is a sealed precision bearing assembly specifically engineered for manual pallet jack load wheel and steering wheel applications. The case-hardened steel construction with double lip seals is optimized for warehouse material handling environments.

Q: What makes the ND99605Z sealing design different?
A: The ND99605Z features double lip seals on both sides of the bearing assembly. This dual-seal design prevents dust, moisture, and fluid ingress, extending bearing life in wet floors, cold storage, and outdoor loading dock conditions.

Q: Is the ND99605Z bearing assembly compatible with electric pallet jacks?
A: The ND99605Z is designed primarily for manual pallet jack applications. While some electric pallet jacks share load wheel and steering wheel assemblies with manual models, verify your specific equipment model before ordering.

Q: Does the ND99605Z require maintenance after installation?
A: No. The ND99605Z is factory pre-lubricated and sealed, requiring no maintenance upon installation. The double lip seals eliminate the need for re-greasing or re-oiling during normal warehouse use.

Q: What bearing material does the ND99605Z use?
A: The ND99605Z uses case-hardened steel rings and balls for superior load capacity and wear resistance. Case hardening increases surface hardness while maintaining a tough, flexible core.

Q: What symptoms indicate the ND99605Z bearing assembly is failing?
A: Replace the ND99605Z if you observe grinding or squealing noise during wheel rotation, visible seal damage or leaking grease, excessive radial play in the wheel hub, or difficulty pushing or steering the pallet jack under normal load.
