Frequently Asked Questions
Q: What is the WW 97-27 roll pin used for on material handling equipment?
A: The WW 97-27 is a spring roll pin used to secure wheel hubs, pump shafts, and pivot assemblies on pallet jacks and electric lift trucks. It acts as a mechanical lock preventing rotation or axial movement of press-fit components.
Q: What are the specifications of the WW 97-27 roll pin?
A: The WW 97-27 has a diameter of 0.1875 inches and a length of 1.25 inches. It is manufactured from spring steel and has a split design that creates radial spring tension within drilled holes. Shear strength is rated at 450 pounds per pin.
Q: What material is the WW 97-27 made from and how does it resist corrosion?
A: The WW 97-27 is made from ASTM A313 spring steel with a zinc-plated finish. The zinc plating provides corrosion resistance in humid and wet storage environments. Under high-moisture conditions, the spring steel core maintains structural integrity longer than soft steel alternatives.
Q: When should the WW 97-27 roll pin be replaced?
A: Replace the WW 97-27 if it shows visible deformation, has lost radial tension, or if the associated component rotates or moves excessively. A roll pin typically lasts the life of the equipment assembly unless subjected to shock loads or vibration damage. Inspect during routine maintenance if movement is detected.
Q: Which pallet jack and forklift manufacturers use the WW 97-27?
A: The WW 97-27 is used across manual and electric pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, and Mitsubishi. It is also compatible with pump truck and load wheel assemblies. Verify the hole diameter and assembly location in your equipment technical documentation before ordering.
