ISAF Mounted Spherical Roller Bearings

dodge isafISAF – Easy On / Easy Off Push-Pull Adaptor Mount System

The Dodge ISAF bearing uses a thin wall push-pull adapter system that achieves clearance setting without the use of feeler gauges. The ISAF bearing is installed by turning the locknut clockwise and removed by a counterclockwise rotation. Installation and removal can be accomplished in 15 minutes or less.

Cost-Saving Installation

• Factory lubed, sealed and adjusted, ready to slip onto the shaft
• Adaptor sleeve concentricity virtually eliminates fretting corrosion
• Field convertible from non-expansion to expansion and expansion to non-expansion
• Elongated pillow block bolt holes to facilitate mounting

ISAF – Better Sealing Options

For low and medium speeds, the TRIDENT™ seal is a triple-lip and a face-rubbing seal that offers an improvement over other systems. While running, the TRIDENT™ seal provides 100% contact at 100% constant pressure, 100% of the time. This patented seal provides a flinger, shielding the seal and bearing from contamination and damage for greater protection. An exclusion lip that makes contact with the flinger provides an additional barrier against contaminants. Seal/land positive contact up to ±1 degree of misalignment.

For high speed or high temperature applications there is a patented Labyrinth seal option that provides excellent sealing for relatively clean or hot environments. It also offers a 15% increase in maximum speed over standard SAF adapter mounted sphericals of the same shaft size. Flinger shields the seal and bearing from contamination/damage. Seal operates up to ±1 degree of misalignment.
