T178 1.5905×2.874×0.748″ Timken Tapered Race Thrust Bearing Timken

TTHD bearings consist of two thrust races, a set of rollers and a cage. This design can create up to 40 percent more capacity than cylindrical and spherical bearings with the same envelope dimensions.

The configuration of TTHD bearings creates a benefit called true rolling motion. The extensions of the raceways and rollers converge at a common point (the apex) on the axis of rotation. As a result, true rolling motion reduces heat generation and wear on the races and rollers.

Design Attributes 

• We make bearings from premium quality, case-carburized bearing steel and feature a hard, fatigue-resistant surface and a durable, crack-resistant core to maximize service life. High-quality materials also provide a high shock resistance in heavy load applications.
• Timken designed TTHDs for high thrust-load capacity and applications with increased pressures.
• The true rolling motion of TTHDs allow for higher speeds with minimum roller skewing or skidding.
• Special profiles on TTHDs create an advanced geometry and minimize edge-stress concentrations caused by high thrust loads.
• Enhanced material, special finishes and increased precision also can be applied to further extend bearing life.
• Additional bearing capacity is available with TTHDFL design, which features a different cage and one flat-thrust race.

 Applications 

Type TTHD bearings are engineered for use in:

• Machine tools
• Mill stands
• Oil well swivels
• Plastic extruders
• Pulp refiners
