  • With more than a century of knowledge and innovation, Timken is an industry-leader in designing, manufacturing and applying high performance engineered bearings into our customers’ most challenging applications. With one common global quality system across all manufacturing plants, we deliver consistent product performance and reliability anywhere in the world. As a Timken customer, you are connected to a team of application, sales and on-site service engineers who help solve unique equipment challenges resulting in extended uptime, productivity and efficiency. We are the recognized global leader in tapered roller bearings with the most extensive offering in the market of inch and metric sizes and assemblies fitting shafts of 8mm to 3m. With capacity to manage both radial and axial loads, Timken® tapered roller bearings are made with various angles and roller lengths to provide a wide range of radial and thrust ratings for optimizing envelope size, minimizing weight, and improving system efficiency. Timken® tapered roller bearings feature precision tolerances, proprietary internal geometries and premium materials for superior durability in millions of demanding applications. Single-row tapered roller bearings are the most widely used type of tapered roller bearing
  • consisting of two main separable parts: the inner race assembly (cone) and the outer race (cup). Single-row tapered roller bearings are typically mounted in opposing pairs on a shaft, with the inherent advantage of being adjustable so they can be set to deliver optimal performance for the application.


  • Available in single, double and multi-row configurations, as well as proprietary sizes
  • Designed in collaboration with OE engineers to design, engineer and test bearings for premium performance in many applications
  • Power dense designs allow for heavier loads and can help extend bearing life
  • Optimized internal geometry lower torque and operating temperatures to extend lubrication system life
  • Can be designed to withstand high-corrosive, high-temperature and vacuum or low-lubrication environments with proprietary enhancements
  • Bearing bore, OD, width or radius have been customized to be different from the basic part number, and are not interchangeable.
