11-141

Frequently Asked Questions

Q: What is the exact specification for SKU 11-141?
A: SKU 11-141 is a high-strength roll pin with 1/4 inch diameter and 1-1/2 inch length, manufactured from zinc-plated ASTM A313 steel. Hardness is 93.5-104 HRB on the Rockwell B scale, meeting ASTM and SAE standards for electric lift truck applications.

Q: What is the intended application for SKU 11-141?
A: SKU 11-141 provides interference-fit retention for gears and shafts on electric lift trucks from Crown, Toyota, Raymond, and Jungheinrich. It prevents shaft rotation and gear slippage during peak load conditions.

Q: Is the zinc plating on SKU 11-141 suitable for wet or outdoor storage?
A: Zinc plating provides moderate corrosion resistance. SKU 11-141 is suitable for indoor and light-duty outdoor storage. In high-humidity or salt-spray environments, inspect periodically for rust or reorder replacement pins if corrosion develops.

Q: Can SKU 11-141 be reused after removal?
A: No. SKU 11-141 is a roll pin with a spring-loaded design that loses tension after initial installation and removal. Always replace with a new pin to maintain proper interference fit and prevent gear slip.

Q: What shaft and bore diameters does SKU 11-141 fit?
A: SKU 11-141 has a 1/4 inch nominal diameter and fits 1/4 inch drilled holes in shafts and hubs. The spring-loaded design creates an interference fit on standard metric and inch-based lift truck components. Verify bore diameter matches before ordering.

Q: What is the shear strength of SKU 11-141?
A: ASTM A313 roll pins at 93.5-104 HRB hardness provide approximately 100,000-130,000 PSI shear strength. This supports gear retention in electric lift trucks under normal load cycles. Verify equipment load ratings to confirm adequate pin strength for your application.
