LOCKWASHER
Frequently Asked Questions
Q: What is the purpose of the SY31193 lockwasher?
A: The SY31193 lockwasher prevents fasteners from loosening due to vibration and repeated loading cycles common in material handling equipment. It maintains bolt tension on critical wheel assemblies, bearing hubs, and frame connections.
Q: What materials is the SY31193 lockwasher manufactured from?
A: The SY31193 is manufactured from hardened steel with surface plating to resist corrosion and wear. The toothed or twisted design provides mechanical resistance against fastener rotation.
Q: Where are SY31193 lockwashers used on pallet jacks?
A: The SY31193 is used under hex bolts securing wheel hubs, load wheels, bearing assemblies, and mast-to-frame connections. Any high-vibration connection point on Crown, Toyota, Raymond, Yale, or similar manual pallet jacks benefits from this lockwasher.
Q: What is the service life of the SY31193 lockwasher?
A: The SY31193 lockwasher typically lasts through multiple reuse cycles if the fastener is removed and reinstalled correctly. However, repeated removal degrades the tooth or twisted design. Replace the lockwasher whenever you remove a fastener that previously used one.
Q: Can the SY31193 lockwasher be used with different bolt sizes?
A: The SY31193 is designed for a specific bolt diameter. Using an incorrect size lockwasher defeats its anti-rotation function. Verify the fastener size in your equipment assembly before ordering to ensure proper fit.
