The TOPBALL slide bush is a              high performance bushing with three times the load capacity, capable of providing up to 27              times normal travel life of a conventional slide bushing.              TOPBALL is available in a variety of configurations to fit various service conditions. NB's              self-aligning TOPBALL can be designed into many different applications such as factory              automated equipment, machine tools, industrial machines, electrical equipment, optical              and measuring instruments.              In the early stages of NB's development of TOPBALL, careful thought and consideration              was given to such factors as quality, cost, performance and interchangeability. The results              of these efforts are reflected in the TOPBALL features.\u003cbr\u003e\u003cbr\u003e\u003cfont size=\"+1\"\u003eTOPBALL FEATURES\u003c\/font\u003e\u003col\u003e\n\u003cli\u003e\u003cp align=\"justify\"\u003e  \t\t\t\tIncreased Load Capacity:  \t\t\t\t\u003cbr\u003e                 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.  \t\t\t\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp align=\"justify\"\u003e  \t\t\t\tLonger Travel Life:  \t\t\t\t\u003cbr\u003e                 Dispersed stress on the load plate provides TOPBALL up to 27 times the travel life of conventional slide bushings.  \t\t\t\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp align=\"justify\"\u003e  \t\t\t\tSelf Aligning Capability:  \t\t\t\t\u003cbr\u003e                 Load plates are thinner at the ends to provide a pivot point at the center of the plate.
