NB now offers a new standard in linear motion with TOPBALL. 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.
TOPBALL FEATURES
Increased Load Capacity: 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.
Longer Travel Life: Dispersed stress on the load plate provides TOPBALL up to 27 times the travel life of conventional slide bushings.
Self Aligning Capability: 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.
Floating Integral Wiper Seal: NB's unique floating seal design allows for selfalignment 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.
Clearance Adjustable: TOPBALL load plates are designed to "float" in the outer sleeve which allows for clearance between the ball elements and shaft to best suit application requirements.
Cost Effectiveness: 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.
