TTHD (Tapered Thrust Heavy-Duty) bearings are engineered for superior load capacity and efficiency. Each bearing features two thrust races, precision rollers, and a durable cage. This advanced design delivers up to 40% more load capacity compared to cylindrical and spherical bearings of the same envelope dimensions. The unique configuration of TTHD bearings provides a critical advantage: true rolling motion. By aligning raceway and roller extensions to converge at a single point on the axis of rotation, TTHD bearings minimize friction. This results in reduced heat generation, less wear on races and rollers, and longer service life for demanding applications.
