RA 811-131

Frequently Asked Questions

Q: What are the material and hardness specifications for the RA 811-131 roll pin?
A: The RA 811-131 is manufactured from alloy spring steel to ANSI B18.8.2 standards with Rockwell C43 minimum hardness. This material composition delivers superior strength and elastic properties compared to standard carbon steel, making it suitable for high-load press-fit applications.

Q: What is the primary application for the RA 811-131 in electric lift trucks?
A: The RA 811-131 is engineered for high-load applications in electric lift truck assemblies. Its alloy spring steel construction and ANSI B18.8.2 specification ensure reliable press-fit retention in critical structural and mechanical assemblies requiring sustained clamping force.

Q: How does ANSI B18.8.2 specification differ from standard roll pin standards?
A: ANSI B18.8.2 defines coiled spring pins with specific dimensional tolerances, material requirements, and performance criteria. This standard ensures the RA 811-131 maintains consistent spring tension, load retention, and fatigue resistance in high-stress mechanical applications across Raymond equipment.

Q: Is the RA 811-131 validated for use on Raymond electric lift trucks?
A: Yes. The RA 811-131 is an OEM part validated for Raymond electric lift trucks. Alloy spring steel composition and ANSI B18.8.2 specification confirm its suitability for demanding high-load assembly applications throughout Raymond lift truck platforms.

Q: What advantages does alloy spring steel provide over standard carbon steel for roll pins?
A: Alloy spring steel offers superior tensile strength, elastic recovery, and fatigue resistance compared to standard carbon steel. The RA 811-131 maintains its clamping force through repeated load cycles without permanent deformation, making it ideal for high-load lift truck assemblies where consistent retention is critical.
