TTHD THRUST BEARINGS

For applications with heavy thrust loads, TTHD Thrust Bearings are designed and manufactured to maximize bearing life and load-carrying capacity. This includes applications such as:  Oil rig swivels and top drives , Crane swivel blocks ,Metal mill work and back-up rolls ,Piercing mill thrust blocks ,Pulp refiners and digesters ,Plastic injection machines and screw-type extruders ,Precision machine tool tables , Radar turntables ,Coal pulverizers ,Gearboxes for vertical rolling mills .The geometry of the TTHD tapered rollers provides increased capacity over cylindrical thrust and spherical thrust bearings with the same envelope dimensions. The extensions of the raceways and rollers converge at a common point (the apex) on the axis of rotation, resulting in true rolling motion. True rolling motion reduces heat generation and wear on the races and rollers. It also allows higher speeds with minimum roller skewing or skidding. Enhanced features, such as coatings and finishes, also reduce film and skidding damage and handle high shock loads.
