NB's uniquely designed ground load plate provides circular arch contact to the ball element resulting in a greater dispersion of the load, enabling TOPBALL to provide three times the load capacity of conventional slide bushings.
Load plates are thinner at the ends to provide a pivot point at the center of the plate. The center acts as a fulcrum to compensate for any slight misalignment between the shaft and the housing bore that might be caused by inaccurate machining, mounting errors or shaft deflection.
NB's unique floating seal design allows for self alignment while maintaining equal and constant contact to the shaft. Seals do not add to the overall length of the bushing allowing for more compact designs.
TOPBALL's higher load capability and longer travel life enables the use of smaller components such as bushings, housings and shafts, reducing material cost and the overall cost of the system. Longer travel life also extends replacement periods and reduce maintenance cost.
