Products Sheave Seals ® are specifically designed for use with Timken’s ® TNASW and TNASWE tapered roller bearing assemblies. The Sheave Seals ® make the bearing assembly a “unitized” sealing unit. Excluder Seals ® are designed for tapered, cylindrical, and spherical roller bearings and for deep grooved, self-aligning, maximum capacity, and double-row ball bearings. They are designed to prevent dirt and debris from entering the bearing cavity. Spent grease can be flushed from the bearing cavity, promoting extended bearing life. Full Face CO and CN Excluder Seals ® are designed for radial ball bearings such as deep grooved, double row, maximum capacity, and angular contact as well as spherical and cylindrical roller bearings that already contain an integral seal or shield. Labyrinth Grease Retainer Seals are designed to retain grease in the tapered roller bearing cavity. Bore Plugs are designed to seal the housing bore and provide easy future access to the shaft. They retain grease and exclude contaminants. Excluder Seals ® and Sheave Seals ® are designed for grease lubricants. They are registered trademarks of Clark Seals Ltd. ® and are designed for tapered roller bearings. . TIMKEN ® is a registered trademark of The Timken Company ® .
