ROLL PIN
Frequently Asked Questions
Q: What is a roll pin and what does the SY52894 do?
A: The SY52894 is a roll pin (also called a spring pin) used in manual pallet jack assemblies to retain and position moving components such as pump shafts, linkage arms, and valve bodies. Roll pins expand slightly when installed in drilled holes to create a secure, reusable fastening point.
Q: Which manual pallet jack models use the SY52894 roll pin?
A: The SY52894 is compatible with various manual pallet jack models from Crown, BT, Bishamon, and other manufacturers. Verify the drill hole size and pin diameter match your equipment specifications before ordering to ensure proper fit and retention.
Q: When should the SY52894 roll pin be replaced?
A: Replace the SY52894 if it becomes loose, bent, corroded, or partially ejected from its bore hole. A loose pin allows excessive movement in pump linkages or valve mechanisms, causing loss of lift pressure or steering control. Inspect roll pins during regular pump maintenance.
Q: What material is the SY52894 roll pin made from?
A: The SY52894 is typically manufactured from spring steel or alloy steel with appropriate hardness for material handling equipment duty. The material provides sufficient strength to withstand repeated pump cycling and movement without permanent deformation under normal operational loads.
