Chesterton 51K seals are high-performance radial seals for heavy duty, dynamic rotary seal applications. These seals provide long-lasting sealing and superior protection against ingress of solid particles, dust and fluids. They protect bearing houses and gearboxes across the heavy indiustries—even in the most hostile working environments.High-performance elastomers used in these seals create resistance to compression setting, wear, and aging. A broad range of engineered elastomers allow use in high and low temperature conditions and provide excellent fluid compatibility. The 51K is manufactured by compression molding technology that provides accurate dimensional, geometrical tolerances and improved fitting. The seal body is equipped with a strong, flexible fabric back for tight fitting within the seal cavity. A helical garter spring maintains the seal lip contact and sealing force on the shaft.
