Frequently Asked Questions
Q: What manual pallet jack brands use the ND7509 bearing assembly?
A: The ND7509 is compatible with manual pallet jacks from Crown, Toyota, Raymond, Yale, Jungheinrich, Clark, and Mitsubishi. It is used in load wheel pivots and lift mechanism assemblies. Verify your equipment model matches the ND7509 specification range.
Q: What material properties does the ND7509 have?
A: The ND7509 is a deep groove ball bearing with hardened chromium steel races, sealed or open design depending on variant, and grease-lubricated construction. Steel races provide load carrying capacity up to typical manual pallet jack specifications.
Q: How often should the ND7509 be serviced?
A: Inspect the ND7509 every 300 operating hours or monthly for visual wear and noise. Lubricate with bearing grease if accessible. Monitor for lateral movement or grinding sounds. Replace the assembly when noise increases or lateral play becomes noticeable.
Q: Is the ND7509 suitable for indoor versus outdoor use?
A: The ND7509 is rated for indoor warehouse and material handling environments. Outdoor or high-humidity storage will accelerate corrosion of the bearing races. For outdoor equipment, specify a bearing with enhanced corrosion protection or sealed double-shield design.
Q: What is a cross-reference part for the ND7509?
A: Related bearing assemblies in our product line include ND7305, ND7506, and ND7605. Cross-compatibility depends on bore and outer diameter matching. Confirm dimensions with your equipment before substituting part numbers.
