  • Higher load capacity and longer travel life - NB's uniquely designed load plate provides circular arch contact to the ball element resulting in a greater dispersion of the load, enabling Topball® to provide up to 3X the load capacity therefore 27X 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
  • Floating seal - NB's unique floating seal design allows for self alignment while maintaining equal and constant contact to the shaft
  • High speed - Topball® meets high speed requirements
  • Topball® unit - This is a Topball® with a housing, the housing has the most appropriate bore tolerance that optimizes Topball®'s performance
  • Tolerance interchangeable with Asian metric slide bush type - Shaft diameter tolerance for TMF and TMA types is the same as Asian metric slide bush
