Frequently asked questions
Common questions about JERGENS from 3G Electric.
What is the maximum load capacity available for Jergens force-indicating hoist rings?
Jergens force-indicating die-flipping pivot and rotate hoist rings are available with maximum capacities ranging from 1,430 lb (M12-1.75 thread) up to 14,770 lb (M36-4.00 thread). Other sizes include 1,650 lb (1/2"-13), 4,100 lb (3/4"-10), 4,630 lb (M20-2.50), and 6,500 lb (M24-3.00). These ratings are for the hoist ring itself and should be verified against the specific application's safety factors and load conditions. The built-in indicator provides visual confirmation of load presence, but it does not replace proper load calculation and inspection procedures.
What materials are used in Jergens ball lock receiver plugs?
The Jergens ball lock receiver plug (MPN 49233) is made of blue anodized aluminum and includes an O-ring for sealing. It has a 20 mm outside diameter, 8 mm overall height, and an M4-0.7 thread size. The anodized finish provides corrosion resistance, while the O-ring helps prevent contaminants from entering the receiver. This plug is designed for use in modular fixturing systems where quick installation and removal are required. For specific chemical compatibility or temperature limits, consult the manufacturer's specifications.
What is the thread size of the Jergens straight-line toggle clamp with locking horizontal handle?
The Jergens straight-line toggle clamp (MPN 70158) features a 5/16-18 plunger thread. It has a locking horizontal handle and flange base mounting. This clamp is used in industrial fixturing and workholding to secure parts during machining, assembly, and other operations. The locking mechanism holds the clamp in the closed position, preventing accidental release. The flange base allows for mounting on flat surfaces. For dimensional drawings and force ratings, refer to the product datasheet.
How does the force indicator work on Jergens die-flipping hoist rings?
Jergens force-indicating hoist rings incorporate a visual indicator that shows when a load is applied. The indicator is designed to provide a clear, binary signal—typically a colored band or pin that moves—to confirm that the ring is under load. This helps operators verify that the load is properly engaged before lifting or rotating. The indicator is not a scale; it does not measure the exact load magnitude. It is intended as a safety aid to prevent lifting without a load or to detect unintended loads. Always follow the manufacturer's instructions for inspection and use.
What are the available thread sizes for Jergens hoist rings?
Jergens hoist rings are available in both metric and imperial thread sizes. Metric options include M12-1.75, M20-2.50, M24-3.00, and M36-4.00. Imperial sizes include 1/2"-13 and 3/4"-10. Each thread size corresponds to a specific maximum load capacity, ranging from 1,430 lb to 14,770 lb. The thread size must match the tapped hole in the die or fixture. Using an adapter or mismatched thread can reduce load capacity and is not recommended. Consult the product specifications for exact dimensions and ratings.
Can Jergens ball lock receiver plugs be used in high-temperature applications?
The standard Jergens ball lock receiver plug (MPN 49233) is made of aluminum with an anodized finish and an O-ring seal. The maximum operating temperature depends on the O-ring material, which is typically nitrile (Buna-N) with a limit around 250°F (121°C). For higher temperatures, alternative seal materials may be available. The aluminum body itself can withstand higher temperatures, but the anodized coating may degrade above certain thresholds. For specific temperature ratings, consult Jergens technical documentation or contact 3G Electric for assistance in selecting a suitable plug for your application.
