Frequently Asked Questions
Q: What are the specifications for the CR 50000-039 roll pin?
A: The CR 50000-039 is manufactured from SAE 1060/1070 case-hardened carbon steel with an oil black oxide finish. Nominal length is 1.5 inches with a diameter of 0.25 inch ±0.002 inch tolerance, ensuring precise fit in hydraulic assemblies.
Q: Which Crown pallet jack models is the CR 50000-039 compatible with?
A: The CR 50000-039 is compatible with Crown PTH 50 manual pallet jacks with serial numbers 7-512501 and higher. Confirm your equipment serial number matches this range before ordering.
Q: What is the difference between SAE 1060/1070 and standard carbon steel?
A: SAE 1060/1070 carbon steel is a higher-carbon alloy that is case-hardened for superior strength and durability in high-cycle industrial applications. The case-hardened treatment provides hardness at the surface while maintaining toughness at the core, ideal for retention pins in hydraulic systems.
Q: What does the oil black oxide finish do?
A: The oil black oxide finish provides corrosion resistance and protects the pin from rust and oxidation during storage and use in the hydraulic unit. It also reduces friction between the pin and surrounding components.
Q: What is the function of this pin in the PTH 50 pallet jack?
A: The CR 50000-039 provides axial retention in the hydraulic unit and linkage assemblies, holding components in precise alignment during raise and lower cycles. It maintains mechanical joint integrity through repeated operational cycles.
Q: How do I verify the CR 50000-039 is correct for my equipment?
A: Check your Crown PTH 50 pallet jack serial number plate. Your equipment must have serial number 7-512501 or higher. If your serial number is lower, your equipment may require a different pin. Contact us with your serial number for confirmation.
