The steel-reinforced Perforated™ Bearing ST consists of several layers of elastomer and intermediate layers of weather-resistant steel, grade WTSt 52-3, bonded together to form a composite laminated spring. By suitable selection of the bearing thickness, the bearing can accommodate large vertical forces as well as large rotational deformations.
for components carrying predominantly static loads
