Frequently Asked Questions
Q: What is the AT Z-1140 lock nut designed for?
A: The AT Z-1140 is a precision-machined lock nut that secures and retains hydraulic assembly components within Atlas Zenith Type 9 manual pallet jack pump units. It prevents fastener loosening under repeated pressure cycling and vibration.
Q: Which Atlas equipment is the AT Z-1140 compatible with?
A: The AT Z-1140 is engineered exclusively for Atlas Zenith Type 9 manual pallet jack hydraulic units. It fits the designated fastener attachment points within the pump assembly and is not compatible with other Zenith generations or alternative brand hydraulic systems.
Q: What material is the AT Z-1140 manufactured from?
A: The AT Z-1140 is constructed from hardened steel with precision machining to ensure consistent thread fit and locking performance under high-pressure service conditions. The material resists corrosion and maintains integrity in typical industrial warehouse environments.
Q: What indicates the AT Z-1140 needs replacement?
A: Replace the lock nut if threads are stripped, if the nut spins without resistance, or if fasteners repeatedly loosen during operation. A stripped or damaged lock nut cannot maintain secure assembly and should be replaced with a new AT Z-1140.
Q: How does the AT Z-1140 differ from a standard nut?
A: The AT Z-1140 is engineered specifically as a lock nut, meaning it has internal locking features or nylon insert design to resist vibration loosening. This ensures components remain secure under the dynamic pressure cycling of hydraulic pump operation.
