Frequently Asked Questions
Q: What is an E-type retaining ring and what does the AT Z-3-68 do?
A: The AT Z-3-68 is an OEM external E-type retaining ring for Atlas manual pallet jack assemblies. It secures components on 0.25 inch diameter shafts and prevents axial movement during load cycles.
Q: What material is the AT Z-3-68 made from?
A: The AT Z-3-68 is manufactured from PH 15-7 Mo stainless steel with 0.025 inch thickness and Rockwell C44 to C51 hardness. Stainless steel construction provides corrosion resistance and exceptional fatigue strength.
Q: Which pallet jacks use the AT Z-3-68 retaining ring?
A: The AT Z-3-68 fits Atlas manual pallet jacks requiring external E-type rings on 0.25 inch shafts. Alternate part references are ATZ368 and AT Z 3 68. Confirm shaft size and model compatibility before ordering.
Q: Can the AT Z-3-68 be reused after removal?
A: E-type retaining rings like the AT Z-3-68 are typically single-use components. Once removed, the ring loses its original tension and grip capability. Replace with a new AT Z-3-68 during reassembly to ensure proper shaft retention and safety.
Q: What diameter shaft does the AT Z-3-68 fit?
A: The AT Z-3-68 is designed for 0.25 inch external shaft applications only. Do not attempt to use on different shaft sizes as this will compromise load retention and component safety.
