24K Slow Rotary Seal

Chesterton 24K Rotary Split Seals, with their robust design, are ideal for low‑speed dynamic rotary seal applications exposed to large shaft runout. These seals provide excellent sealing and protective solutions for heavy‑ duty rotating equipment, even in severe application conditions, thus prolonging bearing and equipment service life.

The flexible, dynamic lip of the 24K creates a positive seal and compensates considerably for shaft runout, which will improve the sealability and reliability of old, worn equipment. The optimum lip pre‑load in combination with high‑performance polyurethane helps to minimize frictional drag on the seal.

The robust, static lip design provides tight sealing in the seal cavity and allows for seal installation in either tandem or back‑to‑back configurations, which provides the flexibility to vary seal systems according to hardware arrangement, operating conditions, and equipment demands. Further, the robust lip provides protection against seal rotation with the shaft.

The 24K split configuration simplifies installation by minimizing downtime for seal replacement and improving equipment uptime and availability. The robust seal design minimizes stretching, bunching, and twisting during installation, which helps reduce the probability of improper installation.

The 24K is manufactured individually using our unique machining process that minimizes the need for tooling costs associated with new sizes. The seals are made to order, with geometrical and dimensional design considerations based on actual equipment arrangement, dimensions, and shaft runout.
