TIMKEN Bearing EE480181D

TDI bearings have a one-piece double inner race and two single outer races and are typically supplied complete with an outer race spacer as a pre-set assembly. The bearing can be used at fixed positions on rotation shaft applications. For rotating housing application it can be used to float on the stationary shaft.

Product description of TIMKEN Bearing EE480181D

TIMKEN Bearing EE480181D, It is Tapered Roller Bearings - Double Tapered Cones - Imperial.Timken® tapered roller bearing assemblies are precisely designed to manage both radial and axial loads, even in the most unforgiving conditions.

Timken offers the most extensive line of tapered roller bearings available anywhere in the world. and related type you may also like TIMKEN Bearing EE526131D.

TIMKEN Bearing EE480181D, Double Tapered Cones - Imperial, Tapered roller bearings are uniquely designed to manage both thrust and radial loads on rotating shafts and in housings. We manufacture nearly 26,000 tapered roller bearing combinations – in single, double and four-row tapered roller bearing configurations. Customized geometries and engineered surfaces can be applied to these tapered roller bearings to further enhance performance in demanding applications.

TIMKEN Bearing EE480181D, Double Tapered Cones - Imperial, Tapered roller bearings consist of four interdependent components: the cone, or inner ring; the cup, or outer ring; the tapered rollers, or rolling elements; and the cage, or roller retainer. The taper angles allow the bearing to handle a combination of radial and thrust loads. The steeper the cup angle, the greater the ability of the tapered roller bearing to handle thrust loads.

Quality and Performance Come Standard The Timken name stands for high quality and outstanding performance.Using our captivities in bearing technology manufacturing, engineering support and distribution, we provide our customers with smart, cost-effective friction management and power transmission solutions that help them outperform the competition.

An analytic tapered roller bearing torque model is presented along with laboratory test data. Initial results of this proposed model are favorable. An accurate general purpose torque prediction tool could be obtained by extending the concepts presented in conjunction with a more comprehensive analysis of actual bearing operating conditions. By using EHL (Elastomer hydrodynamic Lubrication) theory and micro-macro contact analysis, the bearing torque can be determined by predicting each torque component for each roller due to raceway rolling, raceway moments due to EHL pressure distribution, and frictional force of rib-roller end contact. The roughness effect of contact surfaces, effect of EHL film thickness parameter (the ratio of film thickness to composite surface roughness), and thermal EHL effects are also included. A bearing torque test rig, which can measure the torque of cup race, cone race, and rib separately, was built and used to provide test data. Good agreement between the experimentally measured bearing torques and the predictions of the new torque model has been obtained. This torque model will provide a greater fundamental understanding and is more versatile over a wide range of operating conditions.
