Using FEA (Finite Element Analysis) and expertise in seal design, Greene, Tweed has taken the concept behind our renowned AGT® seal, optimized the design of the elastomer and anti-extrusion rings, and developed an Advanced Concept T-ring (ACT).
The ACT® ring is designed with converging sides in order to promote lubrication for reduced friction and wear, with an apex for force concentration under low-pressure conditions to optimize sealing. The design also enhances oil film passage upon the retract stroke for lubrication of the apex of the elastomer. Our in-house tests demonstrate service life increases by as much as 30 percent over some alternative seal designs.
FEATURES & BENEFITS
Improved stability in gland, resulting in reduced stress in the elastomer for enhanced sealing performance
Specially tapered elastomer side wall design reduces friction and promotes efficient seal lubrication ultimately leading to longer seal life
Hydromechanically activated, anti-extrusion rings for enhanced extrusion protection at all sealing pressures
The wide static footprint of the “T” geometry cross-section eliminates spiral failure
Retrofits existing MIL-G-5514/AS4716 and AS4832 glands
Metric series available for metric-sized designs
APPLICATIONS
Accumulators and reservoirs
Actuators (e.g., door actuators)
Flight controls (e.g., spoilers, rudders, aileron, etc.)
Landing gear actuator subsystems (e.g., end caps and static seals, etc.)
Landing gear spare dynamic seals
Landing gear dynamic seals
