Timken Ap Bearings Industrial Applications

When Timken introduced its revolutionary APTM (All-Purpose) railroad bearings in 1954, it was a railroad industry milestone. Decades later, Timken is a leader in the friction management and power transmission industries and continues to lead in advancing bearing technology through continuous innovation and development. In addition to railroad applications, AP bearings are successfully used in many types of industrial applications. This can be attributed to many factors including the bearing’s high load carrying capacity and its adaptability to a wide variety of applications.

Self-contained unit provides substantial cost savings in design and installation. Many mounting parts are available with the bearing assembly. • Pregreased unit reduces installation costs. • Preassembled bearing reduces the number of separate parts to be applied and helps reduce the chance of incorrect assembly. • High quality, tested and improved radial lip seals provide exceptional protection, minimum relubrication and low maintenance. • Positive alignment of rollers is maintained in the bearing due to its basic tapered roller construction. This distributes the load over the entire roller length and helps to prevent rollers from skewing. • On-apex design provides true rolling motion with less friction and more resistance to wear. • Case-hardened and hardened cones, cups and rollers put hardness where it is needed at the working surfaces. The core of these parts, being more ductile, resists the propagation of fatigue cracks and spalls. • AP bearings are adaptable to a wide range of applications in new designs and changeovers from other bearing types. AP bearings range in bore size from 101.6 to 203.2 mm (4 to 8 inches). Optional auxiliary parts can be added to suit a wide range of mounting configurations.
