Frequently Asked Questions
Q: What is the difference between BJ 1120-320000-0A and BJ 1120-320000-00?
A: The BJ 1120-320000-0A is the current OEM gas spring for Big Joe electric pallet jacks. It supersedes and replaces the older BJ 1120-320000-00 and cross-reference part number 112032000000. Both fit the same models, but the -0A is the current production version.
Q: Which Big Joe models use this gas spring?
A: The BJ 1120-320000-0A is designed for Big Joe CB22, D40, E30, EZ30, EZ40, PDS30, PDS40, and S22 series electric pallet jacks. Confirm your model number before ordering to ensure correct fitment.
Q: What material is this gas spring made from?
A: The BJ 1120-320000-0A features a high-grade steel cylinder body designed to resist corrosion and mechanical wear. The sealed gas spring strut uses precharged nitrogen actuation and includes standard clevis end fittings for handle assembly mounting.
Q: What is a clevis end fitting?
A: A clevis end fitting is a fork-shaped connector at the gas spring rod that allows bolted attachment to the lift handle assembly. This design provides a strong, pivoting connection point for the pressurized gas strut to support and control handle movement.
Q: Why is this gas spring precharged with nitrogen?
A: Nitrogen precharged gas springs provide consistent spring force across the full range of motion on the pallet jack handle. Nitrogen is used because it does not react with the seal materials and maintains stable pressure under temperature variations during storage and operation.
Q: What happens if the gas spring develops a leak?
A: A leaking gas spring will lose pressure gradually, causing the pallet jack handle to feel loose or fall under its own weight instead of staying supported. Once a leak develops, the spring cannot be repaired and must be replaced. Do not attempt to refill or reseal a pressurized gas spring.
