Typical Applications
The Goodyear 3B12-304 is a triple convoluted industrial air spring designed for applications requiring high load capacity, vibration isolation, and pneumatic actuation. Its three-convolution bellows design provides a longer working stroke and greater force output than single or double convoluted air springs, making it suitable for demanding industrial environments.
Metal Stamping and Forming Presses
The Goodyear 3B12-304 is widely used in stamping presses, forming machines, and punch presses as a pneumatic actuator. It generates large pressing forces while maintaining smooth, low-friction movement, making it an excellent alternative to conventional cylinders in many industrial applications.
Lifting and Positioning Equipment
Thanks to its high lifting force and compact structure, the 3B12-304 is commonly installed in scissor lifts, lift tables, rotating platforms, and positioning systems. The air spring allows controlled lifting by adjusting air pressure while requiring minimal maintenance.
Conveyor and Material Handling Systems
Many manufacturing plants use the Goodyear 3B12-304 in conveyor loading stations, transfer systems, and material handling equipment. The air spring provides stable support, smooth lifting action, and helps absorb vibration generated during continuous production.
Vibration Isolation Equipment
One of the primary functions of the 3B12-304 industrial air spring is vibration isolation. It is frequently installed beneath machinery to reduce shock, vibration, and structure-borne noise, helping improve machine accuracy while extending equipment life.
