Description

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.
