30330 single row Tapered roller bearings

Short Description:

Single row tapered roller bearings are designed to accommodate combined radial and axial loads and provide low friction during operation. The inner ring, with rollers and cage, can be mounted separately from the outer ring. These separable and interchangeable components facilitate mounting, dismounting and maintenance. By mounting one single row tapered roller bearing against another and applying a preload, a rigid bearing application can be achieved.

The dimensional and geometrical tolerances for the tapered roller bearings is practically identical. This provides optimal load distribution, reduces noise and vibration, and enables preload to be set more accurately.
