TTHD Thrust Bearings Standard features Latest profiling technology 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. Allows for maximum load carrying capacity. Provides higher speed capability (May allow for rib speeds up to 2743 meters/minute or 9000 feet/minute.(1)) True rolling motion Reduces heat generation and wear. Extends bearing life. Premium material Provides high shock load resistance. Maximizes service life in applications with heavy loading. Customized design Ensures best bearing for application. Enhanced features For applications with heavy thrust ® loads, Timken TTHD Thrust Bearings are designed and manufactured to maximize bearing life and load-carrying capacity. This includes applications such as: Super clean steel Coatings/super finish Extends bearing fatigue life. Reduces film and skidding damage for longer service life. Able to handle high shock loads. Subject to approved load level and lubricant flow. Table 1. Features and benefits of TTHD thrust bearings. For more information, visit www.timken.com or contact your Timk
