Tapered Roller Bearings

Tapered roller bearings (TRB’s) from PEER make use of the rolling elements which are shaped like a truncated cone. The reason for this design is that all the tapered surfaces converge at a common point on the bearing centerline, and this yields true rolling motion. Tapered roller bearings are used for lower  speed and high load applications, and also have the ability to accommodate radial & axial loads. The internal angles of the bearing can be custom designed to suit the load of a specific application.

Tapered roller bearings can be arranged face-to-face, back-to-back, or in tandem depending on the application load requirements. Most TRB’s are mounted face-to-face or back-to-back so that axial forces can be supported equally in both directions. Tandem arrangements limit axial load carrying capability to only one direction.

Tapered roller bearings consist of a separable two-piece design (cup and cone); which, enables the end-user to mount each component independently and results in assembly flexibility. PEER mainly concentrates on manufacturing single row (TS), sealed single row (LA), and matched pair tapered roller bearings. A sealed TRB is used to protect the bearing from contamination due to application environment. A matched pair is manufactured with a pre-defined axial clearance which allows user to mount easily while achieving the proper setting for successful bearing operation.  

Due to their ability to handle heavy combined loads, PEER Tapered Roller Bearings are used in many applications within the Agricultural, Off Highway, Fluid, Material Handling, & Industrial Transmission industries and include applications such as tractor axles, ag implements, construction track rollers, hydraulic pumps, bulk conveyor rollers, and speed reducer gearboxes.

No matter what the industry is, PEER application engineers use performance prediction tools to analyze the application and find a bearing that exactly fits the requirement. This allows PEER to specify the right design to meet your performance requirements the first time.
