Frequently Asked Questions
Q: What equipment does the CR 064017-004 Wiper Ring fit?
A: The CR 064017-004 is an OEM wiper ring designed for Crown electric lift truck hydraulic cylinders, specifically Crown M Series Stacker models. It serves as a dynamic rod seal to protect cylinders from contamination.
Q: What are the dimensions and material specifications of this wiper ring?
A: The CR 064017-004 is manufactured from 90A durometer polyurethane elastomer with an AN profile. Nominal inner diameter is 1.50 inches and nominal outer diameter is 1.81 inches. The AN profile geometry is optimized for rod wiping and contamination exclusion.
Q: What is the purpose of a wiper ring in a hydraulic cylinder?
A: A wiper ring removes contaminants, moisture, and debris from the cylinder rod during extension and retraction strokes. This protects internal seals and extends cylinder life by preventing dirt and water ingress into the hydraulic system.
Q: Why is 90A durometer polyurethane chosen for this wiper ring?
A: 90A durometer polyurethane provides a balance of hardness and flexibility needed for dynamic rod wiping. It maintains contact pressure against the rod surface through full extension-retraction cycles while resisting wear and tear from rough or contaminated rods.
Q: Are there cross-reference or superseding part numbers for CR 064017-004?
A: No cross-reference, equivalent, or superseding part numbers are currently available for the CR 064017-004. This is a Crown OEM part with no documented alternatives.
