ShaftSaver Benefits Begin the Moment You Install







	Need to slash your boat maintenance costs? Here are the Top 20 reasons that make the SHAFT SAVER bearing the ideal name for marine and industrial applications: 1. Continuous film lubrication. 2. Expels sand and grit before damage occurs. 3. Withstands heavy bearing loading. 4. Retards slow speed wear. 5. Very low coefficient of friction. 6. 30 -- 120% more bearing area. 7. Maximum wear distribution. 8. Increased shaft speed. 9. Quieter operation. 10. maximum shock absorption. 11. Dampens shaft oscillations at critical engine speeds. 12. Interchangeable with other standard bearings. 13. Negligible moisture absorption. 14. Simplicity of installation and removal. 15. Lowest possible maintenance cost. 16. Confidently used under adverse conditions. 17. Lowest overall wear rate. 18. Adapted to high-speed shafting. 19. Rubber retards wear to new low limits. 20. No shaft wear.

	1. Continuous film lubrication. The SHAFT SAVER design offers an uninterrupted, lubricating film of water under all loads. Back To Top 2. Expels sand and grit before damage occurs. Centrifugal pressures are set up within the bearing and released with every revolution of the shaft. With its release, all abrasive elements are flushed out directly through water and sandways before scoring takes place. Renewal of shaft or shaft sleeves due to scored surfaces is eliminated. Back To Top 3. Withstands heavy bearing loading. The heavier the bearing load, the more efficiently the SHAFT SAVER bearing operates; it automatically builds internal pressure as loads increase. Back To Top 4. Retards slow speed wear. The rotary rubber journal is provided with slow speed water grooves that continually bathe bearing surfaces after normal build-up of water film breaks down. Back To Top 5. Very low coefficient of friction. The coefficient of friction is far below normal due to the introduction of an uninterrupted water film. Back To Top 6. 30% to 120% more bearing area. By adopting a rotating journal, the SHAFT SAVER bearing increases actual bearing areas from 30 to 120 percent (in square inches) over stationary bearings. Back To Top 7. Maximum wear distribution. Conventional marine bearings wear only on the bottom half of the bearing. Our revolving rotor offers a true 360¡ wearing area. Back To Top 8. Increased shaft speed. Regardless of the amount of load, the SHAFT SAVER actually “floats” the shaft on multiple layers of water. A higher shaft speed can be obtained with the same power applied. Back To Top 9. Quieter operation. The SHAFT SAVER is silent under all load and speed conditions due to its soft rubber journal and multiple-layer lubrication. Back To Top 10. Maximum shock absorption. Striking of below-surface objects has far less damaging effects on shafting and gear reduction units due to the SHAFT SAVER'S ability to absorb a great part of the initial impact. Back To Top 11. Dampens shaft oscillations at critical engine speeds. Critical engine speed stern vibration is minimized because every vibration is doubly cushioned by an unbreakable water film and soft rubber. Back To Top 12. Interchangeable with other standard bearings. The SHAFT SAVER bearings are interchangeable with all other standard bore and length bearings. Back To Top 13. Negligible moisture absorption. High-quality compounds make the rubber journal resistant to moisture expansion. Back To Top 14. Simplicity of installation and removal. The SHAFT SAVER bearing is locked to the shaft by simply turning two eccentric locking collars a quarter turn. Reverse the operation to remove them. The actual locking operation requires seconds; no special boring or fitting operations are required. Back To Top 15. Lowest possible maintenance cost. The SHAFT SAVER bearing completely eliminates renewing or replacing prop shafts due to bearing wear. The SHAFT SAVER bearing outwears other bearings by a wide margin. Because of these features, it will reduce time consumed in dry doc for shaft repair or bearing renewal. The SHAFT SAVER bearing sets a new standard for low-levels of maintenance costs. Back To Top 16. Confidently used under adverse conditions. The SHAFT SAVER bearing is effective in shallow water, under heavy load conditions and where frequent shaft inspections must be reduced or eliminated. Back To Top 17. Lowest overall wear rate. Laboratory tests conclusively prove that the SHAFT SAVER bearing will, as a complete unit, and when tested under heavy sand conditions, outlast other bearings — at a rate of three to twelve times. The tests referred to shaft rate combined with rubber wear. Back To Top 18. Adapted to high-speed shafting. Speed boats operate at incredibly high shaft speeds — causing shafting to ride “off center” in direction of rotation. The SHAFT SAVER bearing is designed to permit a change in high-speed shaft positions from 0¡ to 135¡, thus retaining full efficiency throughout the entire top speed range. Back To Top 19. Rubber retards wear to new low limits. Our special wear-resisting compounds will outlast numerous other materials by incredible ratios. Back To Top 20. No shaft wear. Because the SHAFT SAVER bearing is attached to, and revolves with the shaft, there can be no shaft wear. Back To Top
