Frequently Asked Questions
Q: What is the 89-15138-1 lockwasher and what does it do?
A: The 89-15138-1 is a split lockwasher manufactured to ANSI B18.21.1 or DIN 127 standards. It prevents bolt loosening on swivel wheel and handle interfaces of manual pallet jacks by maintaining spring tension under vibration.
Q: What manual pallet jack models use the 89-15138-1 lockwasher?
A: The 89-15138-1 fits manual pallet jacks from Crown, Toyota, Raymond, Yale, Jungheinrich, Linde, and other major OEM brands. Verify your equipment model and bolt diameter match before ordering.
Q: What is the 89-15138-1 made from and how durable is it?
A: The 89-15138-1 is carbon steel with heat treatment for hardness and fatigue resistance. The spring design resists relaxation and remains effective through repeated loading cycles on swivel casters and handle assemblies.
Q: What bolt size does the 89-15138-1 lockwasher fit?
A: The 89-15138-1 is sized for a specific bolt diameter. Confirm the exact bolt size on your equipment before ordering. Mismatched lockwashers do not provide proper clamping force.
